The cells of the embryo sac of an apple plant include
Correct answer: B. Synergids, egg cell, polar nuclei and antipodal cells
- A. Antipodal cells, polar nuclei, sperm cell and tube cells
- B. Synergids, egg cell, polar nuclei and antipodal cells
- C. Synergids, egg cell and generative cells
- D. Tube cells and sperm cell
Explanation
In flowering plants, the embryo sac is the female gametophyte that contains seven cells: two synergids, one egg cell, two polar nuclei (which eventually fuse to form one central cell), and three antipodal cells. The correct answer is Option B. Other options incorrectly include cells that are part of the male gametophyte (pollen grain), such as sperm cells and tube cells.
