Question

Which of the following statements is/are true for sexual reproduction in plants?

(i) Plants are obtained from seeds
(ii) Fertilisation can occur only after pollination
(iii) Two plants are always essential
(iv) Only insects are agents of pollination

Answer 1

Ans) Statements (i) and (ii) are correct.
A seed on germination grows into a new plant and fertilisation in plants can only occur after pollination (i.e. only when pollen grains have fallen on the stigma of flower).
Other statements are incorrect as a plant bearing bisexual flowers can undergo sexual reproduction itself as both male and female reproductive organs are present. Also, along with insects, wind, water, animals and birds are also agents of pollination.
