HORTICULTURE

Detailed explanation-1: -In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower. The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant.

Detailed explanation-2: -Sperm cells within the pollen grain move down the pollen tube and into an ovule. Fertilization occurs as one of the sperm cells fuses with the egg inside the ovule. After fertilization takes place, the ovule develops into a seed that contains a tiny, undeveloped plant.

Detailed explanation-3: -Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.

Detailed explanation-4: -Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.

Detailed explanation-5: -In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style toward clusters of ovules, which hold two female sex cells.
