How many meiotic divisions are required to form 64 pollen grains

Filiform apparatus present at micropylar part of the Synergids help in

What happen to haploid megaspores formed by megaspore mother cell in an angiospermic plant

Which one is the correct evolutionary sequence of gametogenesis

Anther is a four sided structure consisting of four

Assertion: The innermost layer of microsporangium is called tapetum.
Reason: Tapetum performs the function of protection and help in dehiscence of anther to release pollen grains.

Statement I: Megaspore mother cell undergoes meiotic division to form four megaspores.
Statement II: One of the megaspore degenerate and three remain functional.
Statement III: Only functional megaspore develops into female gametophyte.
