Answer 2

Explanation:

Microsporangia are sporangia that produce microspores that give rise to male gametophytes when they germinate. Microsporangia occur in all vascular plants that have heterosporic life cycles, such as seed plants, spike mosses and the aquatic fern genus Azolla.

Each pollen grain is a minute body, of varying shape and structure, formed in the male structures of seed-bearing plants and transported by various means (wind, water, insects, etc.) to the female structures, where fertilization occurs. ... A pollen grain itself is not the male gamete.

The stamen is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium.
