    As the name simplifies this chapter is all about the living creature on this earth. Each organism is different from the other to a lesser or greater extent. Here we will discuss the criteria of the living organism, their identification, classifications and nomenclature i.e. their taxonomy, why organisms are grouped into some category or other.

  • Chapter 2 Biological Classification

    A few letter word diversity is itself a huge variation of a living creature. Have you ever thought of the life form that surrounds us? This is the beauty of nature. In this chapter we will focussed an the R.H. Whittaker biological classification of living organisms. He classified it into 5 kingdoms monera, protista, fungi, plantae and animalia. Here some are microscopic and some are huge but all are living creatures. Whereas no place in biological classification for viruses. What does this mean do viruses non living. You have heard of different viral diseases that mean they have a tendency to multiply with living cells. This is because viruses when outside the host they are non living but when comes in contact with the host body it becomes living. This is a peculiar feature of the virus.

  • Chapter 3 Plant Kingdom

    From the very beginning we studied about plants as they are autotrophs. They prepare their own food since plants are of diverse form as aquatic, herb, shrubs, trees according to the habitat they adapted to specific features. The first level of classification among plants depends whether they have well differentiated parts and secondly on the presence of vascular tissue and finally on the basis of ability if seed persistence. Kingdom plantae is classified into 5 division i.e. Thallophyta, Bryophytes, pteridophyte, gymnosperm, angiosperm and this chapter focus on their life cycle pattern.

  • Chapter 4 Animal Kingdom

    Animals are the heterotrophs they can locomote from one place to another. This is very general that we have studied yet but many more features to explore. In this chapter we will discuss the different phylum and different physiological function. Most important is the body design and differentiation of varieties of animal. According to body design they are classified as porifera, coelenterata, platyhelminthes and many more.

  • Chapter 5 Morphology of Flowering Plants

    Term morphology is the study of external or physical appearance of plants. The parts we see like flowers, leafs, stem, root are the morphological parts of plants. Wide varieties of plants are in our surrounding adapted to different physical features according to the habitat. Some are herbs like grass and huge trees like Eucalyptus with different patterns of leaf, root. In this chapter we will focus on the type of the root, leaf, stem and inflorescence. Seed producing plants are classified as monocot and dicot. Both of them have different types of root system and pattern of arrangement of leaf on stem. Yet one more important aspect is the modification of leaf stem. As we can see in cactus the fleshy leaf like structure is a modified stem known as phylloclade and different other features are explained in this chapter.

  • Chapter 6 Anatomy of Flowering Plants

    This chapter is focussed on the of anatomy of the angiosperm which means the study of internal structure. The plants are made of plant cells and they are grouped to form tissue. Plant tissue that the tendency of cell division is meristematic tissue due to which the growth of plant parts remains continuous. Later the meristematic tissue becomes permanent. Permanent tissue is of two types: simple permanent and complex permanent. Internally the plant has a different arrangement of cell. That determines its shape and size. Monocots do not have well developed vascular tissue in comparison with dicot plants. Monocot leaf, stem and roots are distinct from dicot in various forms this is explained in anatomy of flowering plants.

The cells have capacity for division mitosis and meiosis. This chapter makes us understand how chromosomes divide and distribute in daughter cells.

  • Chapter 9 Biomolecules

    As discussed above the organism is made of cells. They perform vital function. The cells are made of organic macromolecule through these number of metabolic activities that occur and lead the building block of our body. These biomolecules are carbohydrate, protein, lipids, vitamins, nucleic acid etc. In this chapter we will get information regarding the linkage of carbohydrate i.e. glycosidic bond , protein linkage ie. peptide bond and more. Only 20 amino acids are yet known as the combination as these 20 amino acids make millions of proteins, protein are the building block unit of the cell. Emphasis on nucleic acid on how these formed their structure and functions.

  • Chapter 10 Cell cycle and Cell Division

    The fundamental unit of life the cell plays a vital functions one of which is its division. For this the cell enters into an interphase which is 95% of the cell cycle and 5% is the division phase or M phase. There are two type of cell division first is mitosis which is also called equational division because the same number of Chromosomes are present in the parental cell and newly formed daughter cell. Second type is meiosis which is a reductional division where the chromosome from diploid in the mother cell gets reduced into a haploid or half set of chromosomes that only occur in the reproductive cell. While reading this chapter it will be more clear and understandable how step by step the cell undergoes various chromosomal change and finally new daughter cells are formed.

  • Chapter 11 Transport in Plants

    For all the living creatures whether they are microscopic organism plants or animals, everyone needs nutrients for their survival. Plants are stationary and can not locomote yet very interestingly plant adapted the various modes of transport of food, water and essential minerals. Transportation is performed by vascular bundles xylem and phloem. Xylem helps in unidirectional flow of water and minerals from ground through root and transport to various parts of plants. Whereas the food prepared by the leaves through photosynthesis is translocated to various plant parts through phloem. In this chapter we will come to know the various mechanisms of transportation of water and food.

  • Chapter 12 Mineral Nutirtion

    Minerals are the naturally occurring substances that are essential less or more to the metabolic activities in living organisms. Minerals are the growth factors to the plants also. If plants do not get sufficient amounts of nutrients it leads to deficiency disease like necrosis, immature fall, yellow leaf curling of leaf, stunted growth etc. some nutrients are required in less quantity; they are known as micronutrients but if they are required in large quantities they are said to be macronutrients. If in case the nutrient gets rich or uptake of nutrient is more than that of standard value it leads to toxicity like other organism plants also need balanced amounts of nutrient. In this chapter we will come to know different metal on and nonmetal ions are used by plant growth and deficiency and toxicity affect the plant growth and cause of disease.

  • Chapter 13 Photosynthesis in Higher Plants

    From our childhood we are knowing about plants are autotrophs they synthesize their own food by the process of photosynthesis.

In this chapter we will study the geometric and arithmetic growth model with different phytohormone like auxin, gibberellin, cytokinin, abscisic acid, ethylene with this we will focus on photoperiodism and vernalisation. These two phenomenon are influenced by abiotic components like farther is based on intensity of light period and later one on cold temperature. We will come to know about interaction of abiotic components with plants.

  • Chapter 16 Digestion and Absorption

    Animals are heterotrophs, they feed on others to get nutrients for survival. Different organisms had adapted various methods of intaking food. In this chapter we will discuss human digestion and absorption. Humans get food from plant and animal products that are rich in certain and might contain essential nutrients like carbohydrate, protein, lipids, and vitamins for various metabolic activities. In this chapter the main areas of focus is digestive gland and how digestion of different macromolecules occurs and is absorbed by the intestine. Regulatory mechanism and disorders.

  • Chapter 17 Breathing and Exchange of Gasses

    In the previous chapter we discussed breaking down food into simpler substances like glucose, amino acid and fatty acid. Each and every physiological activities in our body is interconnected to each other. We know about breathing, inhaling oxygen and exhaling of co2. How efficiently our body organ coordinates ,digested foods comes into blood and the air inhaled through the respiratory tract reaches to lungs and finally to the blood where oxidation of food occurs to produce energy for various vital functions of the body. This chapter covers the respiratory system of the human, function of different parts of the respiratory system, Breathing mechanism, Regulatory mechanism on and Disorder of respiratory system.

Regulatory mechanism of heart activity and disorder of the circulatory system.

  • Chapter 19 Excretory products and their Elimination

    Human body produces various harmful substances due to different metabolic activities that have to be removed by our body such as urea,Uric acid ,ammonia ,co2 etc. This work is performed by the kidney, lungs and skin. The nitrogenous waste like urea, uric acid and ammonia are removed and filtered from the blood through the kidney. Various organisms have different excretory organs like protonephridia, nephridia, green gland, malphigian tubule and the most advanced or complex one is kidney. This chapter focus on the structure of the kidney, it unit nephron ,countercurrent mechanism the process of concentration of urine. Regulatory mechanisms like rennin. angiotensin mechanism and disorders of excretory system.

  • Chapter 20 Locomotion and Movement

    These chapters make us feel very excited how animals can move their hand, neck and other body parts so they can locomote from one place to another. Movement and locomotion can be done by contraction and relaxation of muscle. In this chapter we will come to know about the type of muscle and their function. Smooth muscles perform involuntary action whereas unsmooth muscles or straited muscle perform voluntary action. Here we will also understand the mechanism of muscle contraction most common is the sliding filament mechanism. Role of actin and Myosin in contraction. Human skeletal system various types of bones and the joint and disorder of muscular system.

  • Chapter 21 Neural Control and Coordination

    Humans are the most advanced mammals. Humans can memorise, think, create , feel the sense all the work done is through our brain. In this chapter we will cover the Human Nervous system, Brain, Spinal cord and the nerve that arises from them. In your previous class you have read about a unit of the nervous system is neuron or nerve cell. These nerve cells are the longest cells in humans and perform the function of transmission of signal from brain to other part or from other part of body towards brain. Chapter reveals the structure of the brain and their parts. Brain works still when we are in sleep, we see with the eye, we smell with the nose and other senses but Brain interprets what we see, the taste, smell and feel. Here we will also cover the structure and working of the human eye and ear.

  • Chapter 22 Chemical Coordination and Integration

    In the previous chapter we discussed the nervous system and its working but control and coordination in the organism is incomplete without an endocrine system or hormonal system. Both these systems work in synchronised manner to make all physiological functions to perform. Digestion, respiration, reproduction to all are regulated Neurally and chemically by these two systems. This chapter will surprise you with how metabolic activities are controlled by hormones. These chemical messages are responsible for growth, respiratory process, digestion and other.

  • Chapter 1 Sets

    Set plays a very crucial role in understanding the fundamentals of mathematics. To be precise, a set is an assembling or collection of items. With the concept of set, we can analyse many real life situations and other branches like biology, computer science, engineering etc. in a better way. It consists of set representation, finite and non-finite sets, equal sets, universal set, subset, venn diagrams, Union and intersection, complement of set, etc. It forms the basis for relation and functions. Venn diagrams are pictorial representations of sets as closed curves.

  • Chapter 2 Relations & Functions

    With the knowledge of relations and functions, you can associare different pairs of objects from two sets which are represented as closed - curves. Basically they derive a relation between two objects. Functions are nothing but a special type of relation. This chapter consists of ordered pairs, cartesian product of sets, finding the number of elements, domain, co-domain , Range of functions. Real valued functions like polynomial, signum, etc. and their graphs. Idea of function is very much needed for association of one object to a particular type of object.

  • Chapter 3 Trignometric Functions

    In previous class, we have discussed basic identities, trigonometric ratios and their applications in finding the distances between two real life objects. Now we extend the concept of trigonometric ratios to trigonometric functions. In this chapter, we will discuss about measurement of angles, conversion of angles from radian to degree and vice-versa, Definition of trigonometric functions with the help of unit circle, signs of functions in quadrants, domain, range and graph of functions, sum & product formulas, multiple angles formulas. General Solution of trigonometric equations.

  • Chapter 4 Principle of Mathemetical Induction

    This chapter is all about proving the given statement is true or not by the process of induction. We deal with natural numbers because it is the least inductive subset of real numbers. Least inductive means it has the least fixed point for an operation definable by a positive formula for some natural number n. In this chapter, we will discuss the principle of mathematical induction and its simple applications.

  • Chapter 5 Complex Number & Quadratic Equations

    Upto now, we are very much familiar with real numbers. But in solving quadratic equations, real numbers have no answer about -1 i.e, square root of negative numbers. Set of real numbers is a subset of complex numbers. Complex numbers give answers to these questions. This chapter consists of algebraic properties of complex numbers, argand plane , polar representation of complex numbers , fundamental theorem of algebra , Solution of quadratic equations in complex number systems. Square root of a complex number.

  • Chapter 6 Linear Inequalities

    We are familiar with equations, which we get when a polynomial equates to some constant. But when this equals sign replaced with greater than or less than sign, we get inequalities. Not only in maths, it has some real life applications like how many products should be produced for maximisation of profit and comparison of heights of two persons, etc. This chapter consists of linear inequalities, algebraic solution of linear inequalities in one variable and their representation on number line, Graphical solution of linear inequalities and system of linear inequalities in two variables.

  • Chapter 7 Permutations & Combinations

    When it comes to counting or arranging the things, we can do it manually but for that data should not be very large. When the data is large then we have to adopt some methods. These methods will be discussed in this chapter. Permutation is a form of arrangement of 'n' items taking 'y' at a time. Combination is the number of ways for choosing 'r' items out of 'n' items. This chapter consists of fundamental principle of counting, factorial (n!), permutation and combination and derivation of their formulae and their connections, also their simple applications.

  • Chapter 8 Bionomial Theorem

    An algebraic expression containing two terms and connected by (+) & (-) operation is called binomial. When small positive powers are raised to a binomial it can be solved manually. For higher powers it becomes very difficult to solve. But the binomial theorem helps to solve expressions which have large powers. It has many applications like in permutation and combination, probability, etc. The topics which are included in this chapter - proof of binomial theorem for positive integral indices, Pascal's triangle, general and middle term in binomial expansion and its applications.

  • Chapter 9 Sequence and Series

    Sequence is a collection of objects taken one by one in which repetitions may present but order matters. It can have any number of terms. When these terms are added it is called a series. We get some general expressions to solve sequences and series. It solves very tedious calculations which are very difficult to solve manually. This chapter consists of arithmetic progression and mean, geometric progression and mean, general terms, sum of n terms, arithmetic and geometric series, infinite G.P, relation between A.M and G.M, some special series.

  • Chapter 10 Straight Lines

    In earlier classes, you have read about lines in the Euclid geometry section. That is just an introduction but now we go in depth of lines and its various aspects. Concepts of lines are very essential to know about conics and 2d-3d geometry, which we will discuss later. This chapter consists of basics of 2d geometry, shifting of origin, slope of line, angle between two lines, various forms of equation of line point - slope form slope intercept form, two points form, intercept form, normal form, etc., general equation of line, distance of a point from a line, equation of family of lines.

  • Chapter 11 Conic Secrtions

    We are familiar with various concepts of lines, now we have to know about conic section. For various sections of cones like circle, ellipse, parabola, hyperbola etc. we need to go through the details of this chapter. The knowledge which we gain through it has great importance. These figures are related to our real life also like the shape of an egg is elliptical. It will be very interesting to know about them. This chapter has topics such as circle, ellipse, parabola, hyperbola, a point, a straight line, a pair of intersecting lines as a degenerate case of a conic section, standard equations of sections of cone.

  • Chapter 12 Introduction to 3 dimensional Geometry

    After the knowledge of 2d geometry, it is time to add a new dimension to the geometry after that it is called 3d geometry. This is just an introduction but details of this chapter is in the next class. This chapter is for basics. This chapter consists of coordinate axis and coordinate planes in three dimensions, coordinates of a point, distance between two points and section formula.

  • Chapter 13 Limits And Derivatives

    This chapter is an introduction for a branch called calculus. Calculus is that branch of mathematics which is associated with the study of change in the value of functions as the points of domain change. This chapter will help us to understand differentiation and integration which we study in next class. Topics of this chapter are limit of function introduced as rate of change of distance function and its geometric meaning, definition of derivative, derivatives of sum, difference product and quotient of functions, derivatives of polynomial and trigonometric functions.

  • Chapter 14 Mathematical Reasoning

    If we consider mathematics, there are mainly two types of reasoning - 1) Inductive reasoning, 2.) Deductive reasoning. Inductive reasoning is studied in principle of mathematical induction. Deductive reasoning will be discussed in this chapter. Examples or situations in this chapter mostly related to real life and some with mathematics. This chapter consists of mathematically acceptable statements, connecting words/phrases - "it and only if", "implies”, "and/or", "implied by", "there exists” and their use through variety of examples related to real life and mathematics, difference between contradiction, converse and contrapositive.

  • Chapter 15 Stastistics

    This branch of Mathematics deals with a large number of data. When data is large it is very difficult to handle and we can not reach the exact result if we do it manually. Some methods are necessary for this and these methods will be provided in this chapter. Some topics are studied in earlier classes such as 8,9,10. Now, we extend our periphery. This chapter consists of measures of dispersion; mean deviation, variance and standard deviation of ungrouped/grouped data, analysis of frequency distributions with equal means but different variances.

  • Chapter 16 Probability

    Before happening at any event, we can only think about the possibilities of happening but we cannot be sure about it until it happens. This chapter has always been an interesting topic in Mathematics. We are familiar with the basics of probability in earlier classes. Now some advanced topics will be discussed. These topics are random experiments; outcomes, sample spaces, occurrence of events, 'not', 'and' & 'or’ events, exhaustive events, mutually exclusive events. Probability of an event, probability of 'not', 'and' & ‘or’ events, axiomatic probability.
