male gamete
pollen grain
anther
none of these​

Answer 1

Microsporogenisis is the formation of Pollen Grains.

• Generally, anther is tetrasporangiate, i.e., four microsporangiate situated at four corners.

• Each sporangiate consists bunch of parenchymatous cells termed as Sporangium tissue.

• The primary sporogenous cells form diploid microspore mother cells.

• Further, microspore mother cells undergo meiosis to form haploid microspores. They get arranged in form of a tetrad.

• Microspores develop into Pollen Grains on attaining maturity.

• At the time of dehiscence, the ephemeral middle layer walls breaks down releasing the pollen grains.
