Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In an embryo sac, the cells that degenerate after fertilization are
A
Synergies and primary endosperm cell
B
Synergids and antipodal cell
C
Antipodal cell and primary endosperm cell
D
Egg and antipodals
Explanation: 

Detailed explanation-1: -It leads to the formation of the typical female gametophyte or embryo sac Synergids and antipodals degenerates after fertilization. So, option B is correct.

Detailed explanation-2: -Final answer : Synergids and antipodals.

Detailed explanation-3: -Solution : Degenerate Explanation: Before fertilization, the antipodals and synergids are distinctly present at chalazat end and micropylar end, respectively in an embryo sac. After fertilization these structures, antipodals and synergids gradually degenerate.

Detailed explanation-4: -The specific function of antipodal cells is unknown. After fertilization, these cells degenerate.

Detailed explanation-5: -Synergids and antipodals are the cells that are present in the embryo sac at the time of fertilization. Once the fertilization of the male gamete and the egg occurs and the zygote is formed. The synergids and antipodal cells degenerate after that and the ovary converts into a fruit.
