The anther wall consists of four wall layers where

The wall of a house consists of two layers with different thermal conductivity coefficients. The ternpera ture of the outer wall is T_1 and that of the inuer wall is T_2 . Temperature variations inside the wall are shown in the figure. What layer, the inner or the outer, has a higher thermal conductivity coefficient?

Microsporangium of anther is surrounded by four wall layers. Name the wall layer which nourishes the developing pollen grains.

Fill in the blanks: E. The anther wall is composed of …….. to ………. layers.

Assertion : A typical microsporangium of angiosperms is generally surrounded by four wall layers - epidermis, endothecium, middle layers and tepetum. Reason : The outer three wall layers perform the function of protection and help in dehiscence of anther to release the pollen.
