Question

What is fertilisation?

Answer 1

Fertilisation is the process by which a sperm cell fuses with an egg cell to form a zygote, which later develops into an embryo. It is a crucial step in sexual reproduction, where two gametes (sperm and egg) combine their genetic material to create a new individual with a unique set of genes. Fertilisation typically takes place internally in most animals, while in plants, it can occur through pollination and the transfer of pollen grains to the ovules.
