How many cells are present in a typical mature angiosperm embryo sac?
Answer and explanation
Correct answer: Seven
A typical mature angiosperm embryo sac is seven-celled and eight-nucleate. It contains three cells forming the egg apparatus, three antipodal cells, and one central cell. The central cell contains two polar nuclei, so there are eight nuclei but only seven cells. This distinction makes seven the unambiguous answer.
