The embryo sac of an angiosperm is made up of
- A 8 cells
- B 7 cells and 8 nuclei
- C 8 nuclei
- D 8 cells and 7 nuclei
Answer & Solution
Correct Answer
(B) 7 cells and 8 nuclei
Step-by-step Solution
Detailed explanation
(B) 7 cells and 8 nuclei,
The embryo sac of an angiosperm has 7 cells, which include the egg cell, two synergids, three antipodal cells, and one central cell. The total number of nuclei is 8, as the central cell contains two nuclei (polar nuclei).
