- A 4 cells arranged symmetrically around one single, large central vacuole space
- B 6 cells, each one carrying a single diploid nucleus derived from the megaspore
- C 8 nuclei in 7 cells (including egg, two synergids, two polar nuclei, three antipodals)
- D Just the egg cell, surrounded entirely by several layers of sterile nucellus tissue
Correct answer: C. 8 nuclei in 7 cells (including egg, two synergids, two polar nuclei, three antipodals)
Explanation: Mature embryo sac: 8 nuclei in 7 cells: 1 egg cell, 2 synergid cells, 1 central cell (2 polar nuclei), 3 antipodal cells.
