Question

The megaspore mother cell and the microspore mother cell ______.

Options

• both produce pollen grains

• both divide meiotically

• both divide mitotically

• produce pollen grains and embryo sacs, respectively

Answer 1

The megaspore mother cell and the microspore mother cell both divide meiotically.

Explanation:

The megaspore mother cell undergoes meiosis to form megaspores, one of which develops into the embryo sac (female gametophyte). The microspore mother cell also undergoes meiosis to produce microspores, which develop into pollen grains (male gametophytes). Hence, both cells divide meiotically but produce different gametophytic structures.
