Question

The embryo sac of an Angiosperm is made up of

• A. 8 cells
• B. 7 cells and 8 nuclei
• C. 8 nuclei
• D. 7 cells and 7 nuclei

Answer 1

The correct option is B 7 cells and 8 nuclei

8 cells:

The embryo sac has one central cell with two polar nuclei. Therefore, the number of cells is 7 and not 8.

7 cells and 8 nuclei:

The seven cells in the embryo sac include one egg cell, two synergids, three antipodal cells and one central cell. Each cell has one nucleus except the central cell that has two polar nuclei. So there are 8 nuclei.



8 nuclei:

The embryo sac has a total of 8 nuclei. This answer is incomplete as nothing about the number of cells has been mentioned.

7 cells and 7 nuclei:

The embryo sac has 7 cells but not 7 nuclei, rather they have 8 nuclei.

Final answer:

b. 7 cells and 8 nuclei
