Biology Question on Angiosperms
Typical mature embryosac of angiosperm is
A
8 nucleated 1 celled structure
B
8 nucleated 8 celled structure
C
8 nucleated 7 celled structure
D
7 nucleated 8 celled structure
Answer
8 nucleated 7 celled structure
Explanation
Solution
The embryo sac, also known as the female gametophyte, is the structure within the ovule of an angiosperm that contains the egg cell and other cells involved in fertilization and seed development.
The mature embryo sac of angiosperms is commonly referred to as the "7-celled, 8-nucleate" structure. It consists of three antipodal cells at one end, two synergids located near the egg cell, a central cell with two polar nuclei, and the egg cell itself.
Therefore, the correct answer is (3) 8 nucleated 7 celled structure.
