Answer:
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.
You would need more than natural phenomena for a scientific theory because a theory is a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
