Question

How does the process of fertilisation take place in flower

Answer 1

The male component of fertilization in flowering plants is pollen. It consists of two or three gametophytes containing the tube cell and germ cell. The tube cell grows into a pollen tube, while the germ cell divides through mitosis. Pollination brings the male pollen into the female stigma of a flower with the help of pollinators. Large flowers mostly attract insect pollinators, while smaller flowers use the wind to pollinate. The pollen is then transferred into the pistil or gynoecium, which contains the stigma, receptacle, ovary and style. Its tube cell sticks to the receptive stigma and starts to develop into a pollen tube. The male germ cell releases two sperm cells that travel to reach the flower’s ovum. While the male cell grows, the female cell in the ovule develops. One of the sperm cells fuses with the egg, while the other forms an endosperm tissue, which serves to nourish the growing zygote or seed. After fertilization occurs, the ovary wall becomes a fruit.

Answer 2

when rioe pollen from an anther of the same kind of flower cathes on the sitgma each pollen gain send out tiny threadthlike tube the tube grow down through the style and pierces one of the ovules in the ovary.

thi is how fertiliza tion take place in flower
