In an embryo sac, the cells that degenerate after fertilisation are
(A) Synergids and primary endosperm cell
(B) Synergids and antipodals
(C) Antipodals and primary endosperm cell
(D) Egg and antipodals

A

Synergids and primary endosperm cell

B

Synergids and antipodals

C

Antipodals and primary endosperm cell

D

Egg and antipodals

Text Solution

Verified by Experts

The correct Answer is:
B
In non fertilized embryo sac, Antipodal cells and synergid cells are clearly located near mycropyle and chalaza respectively. While in fertilized embryo sac, antiopodal cells and synergid cells are slowly destroyed after the formation of zygote
