Question

When do microspore tetrad dissociate from each other?

Answer 1

Answer:

Microsporangium is a structure in the plant’s male reproductive organ where the development of pollen takes place.

Structure of Microsporangia

A microsporangium appears to have a circular outline when viewed transversely. It is surrounded by four layers:

Epidermis

Endothecium

Middle layers

Tapetum

The outer three layers protect the pollen and help in the splitting of anther to release the pollen. The tapetum nourishes the pollen grain. The cells of the tapetum are multinucleated and have dense cytoplasm. A young anther comprises of a group of compactly arranged homogenous cells called sporogenous tissue.
