Question

Rearrange the following events of sexual reproduction in the sequence in which they occur in a flowering plant: embryogenesis, fertilisation, gametogenesis, pollination

Answer 1

Events in sexual reproduction:

Events occurring in sexual reproduction are as follows:

● Pre-fertilisation events

● Fertilisation

● Post-fertilisation events

Pre-fertilisation events:

Events occurring before fertilisation are referred to as pre-fertilisation events. It includes the following:

● Gametogenesis: Production of male and female gametes

● Gamete transfer: The process of transferring pollen grains from the male anther of a flower to the female stigma

Fertilisation:

Fusion of male and female gametes is called fertilisation resulting in the formation of zygote.

Post-fertilisation events:

Events occurring after fertilisation are referred to as post-fertilisation events. It includes the following:

● Zygote formation: Formation of zygote due to fusion of gametes

● Embryogenesis: Process of the development of an embryo from a zygote

Final answer

Gametogenesis → Pollination → Fertilisation → Embryogenesis
