Draw a diagram of the transverse section of an angiospermic anther .Label any six parts
Answers
Answer:
Male reproductive part of a plant consists of an anther and the filament. Anther is bilobed containing 4 microsporangia in angiosperms so it is known as dithecous anther. Each microsporangium contains spores that produce male gametes. It has following layers:
The outermost layer is known as the epidermis.
Inner to the epidermis is the layer of endothecium.
Inner to endothecium, there are 2-3 cell middle layers that usually disintegrate during anther maturation.
The innermost layer is known as tapetum.
Inner to the tapetum are the microspore mother cells which give rise to pollen grains through meiotic division.
