Question

The egg apparatus of angiosperms comprises

• A. an egg cell and two antipodals
• B. an egg cell and two synergids
• C. an egg cell and two polar nuclei
• D. an egg cell and the central cell.

Answer 1

The correct option is B an egg cell and two synergids

Angiosperms are vascular plants. They have stems, roots, and leaves. Unlike gymnosperms such as conifers and cycads, angiosperm's seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. A group of three cells in the seven-celled embryo sac of an angiosperm (flowering plant) consisting of the egg cell and two associated cells called synergids. The egg apparatus is located at the end of the embryo sac closer to the micropyle (the opening through which pollen nuclei enter the ovule.) The synergids are thought to help direct the pollen nucleus to the egg cell as part of the process of double fertilization characteristic of angiosperms. The synergids degenerate after the egg cell has been fertilized.

So the correct option is 'an egg cell and two synergids'.
