Tick the correct answer:

(a) The reproductive part of a plant is the
(i) leaf    (ii) stem    (iii) root    (iv) flower

(b) The process of fusion of the male and the female gametes is called
(i) fertilisation          (ii) pollination
(iii) reproduction      (iv) seed formation

(c) Mature ovary forms the
(i) seed                   (ii) stamen
(iii) pistil                  (iv) fruit

(d) A spore producing plant is
(i) rose                   (ii) bread mould
(iii) potato              (iv) ginger

(e) Bryophyllum can reproduce by its
(i) stem                  (ii) leaves
(iii) roots                (iv) flower

Answer

(a); (iv) Flower                                                                                                                                                                                                                              Flowers are the reproductive part of a plant that contains Stamens and pistils which are the male and the female reproductive part of a plant respectively.

(b); (i) Fertilization
The process of fusion of gametes of male and female (egg) to form the diploid zygote in the embryo sac is called fertilization.



(c); (iv) Fruit
Ovary contains ovules that develop into seeds after the fertilization process. After that the zygote differentiates to form an embryo sac inside the ovule. The ovary matures to turn into the fruit which can either be fleshy or dry, in which the seeds are embedded in them. A fruit is mainly formed as the result of cell division, expansion and differentiation in the ovary; or the results of stimuli received from pollination as well as from the seeds that are developing. 

(d); (ii) Bread mould
Spore is a unit of reproduction in plants which may also be used for dispersal as well as for survival in unfavourable conditions spore- producing plants include ferns, mushroom, liverworts, hornworts and mosses etc.

(e); (ii) Leaves
Bryophyllum is a group of plant species of the family Crassulaceae and can reproduce by its leaves, i.e. reproduces asexually.
