Question

Which of the following is the correct sequence of events of sexual reproduction in a flower?

Options

• pollination, fertilisation, seedling, embryo

• seedling, embryo, fertilisation, pollination

• pollination, fertilisation, embryo, seedling

• embryo, seedling, pollination, fertilisation

Answer 1

pollination, fertilisation, embryo, seedling

Explanation - 

During sexual reproduction, the first event that occurs is pollination, that is, transfer of pollen grains from the anther to the stigma. After pollination, pollen grain germinates on the stigma to form pollen tube which carries male gametes to the egg present inside the ovule for fertilisation. After fertilisation, a zygote is formed which develops into an embryo and ovule develops into a seed. On seed germination, embryo develops into a seedling under appropriate conditions.
