Question

Observe the following part of a flowering plant prepare a note.

Answer 1

It is the part of plant reproduction system. The whole process starts with the reproduction in the flowers – pollination and then the pollen is transferred from one stigma to another or sometimes the same flower.

The pollen grains then shift to ovule where two sperm nuclei pass through the tube and one will fertilize the egg to produce a zygote.

Another one will form endosperm nucleus with polar nuclei. In the end, seeds are formed.

Answer 2

hii here is you're answer!!

1. An ovule is an egg shaped structure attached by a stalk (Funicle) to the inner side of the ovary.
2. Depending upon the species of plant involved, an ovary may have one, two, severed or even hundreds of ovules.
3. At the center of each ovule there is a microscopic embryo sac filled with food and water.
4. The embryo sac is composed of gametophyte cells.gametophyte cells
5. The majority of flowering plants have an embryo sac consisting of seven cells and eight nuclei.
6. They are one egg (female gamete), two synergids, one central cell (secondary nucleus) and three antipodals.
7. Central cell contains two nuclei, they are called polar nuclei.
