Class 10 Science - Chapter Life Processes NCERT Solutions | Where do plants get each of the raw mate
Where do plants get each of the raw materials required for photosynthesis?
Photosynthesis is the anabolic process by which green plants (autotrophs) synthesize their own food in the form of glucose or carbohydrates from the simple inorganic compounds like carbon dioxide and water. So, this process is the transformation of light energy into the chemical energy to make their food in their own food,i.e, carbohydrates by green plants.
So, the following raw materials are required like carbon dioxide, water, chlorophyll and sunlight to make complex organic material from the simple inorganic material.
-
Carbon dioxide:- carbon dioxide is taken up from the atmosphere through the stomata and releases oxygen.
-
Water:- plants take water from the soil through the roots to the leaves. And, the transportation of water from the soil to the roots and then to the root cortex and then finally transported to the leaves from the stem occurs through the xylem.
-
Sunlight is obtained from the sun to make the food, necessary for the producers (green plants).
-
Chlorophyll:- when organisms take carbon dioxide and water from the environment, they use sunlight and convert them into the glucose or oxygen and this is taken up by the chlorophyll.
