Answer 2

Answer:

The development of pollen grain occurs in Microsporangia.

Explanation:

• In a plant's male reproductive organs, pollen development takes place in a structure known as the microsporangium.

• The microsporangia are usually bi-lobed structures or pollen sacs.  

• The microspores develop into pollen grains inside the pollen sac.

• Microsporangia are borne on the lower surfaces of the microsporophylls.

• The cells that undergo meiotic division to produce haploid microspores are present within the microsporangia.
