Megasporocytes will eventually produce which of the following?
pollen grain
sporophytes
male gametophytes
female gametophytes

female gametophytes

Explanation:

The cell called megasporocyte (2n) is usually the mother cell of the megaspores, which are the female spores of spermatophyte plants.

After an meiosis, the megaspore mother cell (2n) will give rise to 4 megaspores (n).  Three of these megaspores usually degenerate.  The functional megaspore will then develop into the megagametophyte, which will be called the embryonic sac.  Initially the megaspore grows and its nucleus divides.
