Fertilization in Plants
Fertilization in plants occurs after pollination and germination. Pollination occurs through the transfer of pollen – which is the male microgametes of seed plants, producing the sperm – from one plant to the stigma (the female reproductive organ) of another. The pollen grain takes up water and germination occurs.
The germinated pollen grain sprouts a pollen tube, which grows and penetrates the ovule (the egg structure of the plant) through a pore called a mycropyle. The sperm are then transferred through the pollen tube from the pollen.
In flowering plants, a secondary fertilization event takes place. Two sperm are transferred from each pollen grain, one of which fertilizes the egg cell to form a diploid zygote. The nucleus of the second sperm cell fuses with two haploid nuclei contained within a second female gamete called the central cell. This second fertilization forms a triploidcell, which subsequently swells and develops a fruiting body

Question ⤵️
Explain how fertilisation takes place in flowering.
Answer ⤵️
Fertilization in flowering plants happens through a process called pollination. Pollination occurs when pollen grains from the anther land on a stigma. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed.
