Which of the following wall layers of anther play a predominant role in its dehiscence
1 Tapetum
2 Epidermis
3 Middle layers
4 Endothecium
Explanation:
The hypodermal layer of the anther wall present just beneath the epidermis is called as endothecium and remains in the mature anther. The endothecial cells over the junction of the two sporangia do not undergo secondary thickening. And such fibrous bands are important for supplying the mechanical force for anther dehiscence.

Another name for Pollen sac is
1 Embryo sac
2 Anther
3 Microsporangium

In anther culture, the androgenic haploid plants are obtained from
1 Anther wall
2 Anther tapetum
3 Connective tissue
4 Young pollen grain
Explanation:
Androgenic haploid plants are the haploid plants produced through anther or pollen culture. The male gametophyte produces the haploid plants in this case. Haploid plants are grown from immature pollen grain or microspores (male gametophytic cells).

The outer three layers of microsporangium perform the following functions?
1 Protection to developing pollen
2 Provides nourishment to developing pollen
3 Helps in the dehiscence of anther to release pollen
4 Both (1) and (3)
Explanation:
The epidermis, endothecium, middle layers and the tapetum. The outer three wall layers perform the function of protection and help in dehiscence of anther to release the pollen.
