Biology Question on sexual reproduction in flowering plants
Which one of the following layer of the anther wall helps in its dehiscence ?
A
Epidermis
B
Middle layer
C
Endothecium
D
Tapetum
Answer
Endothecium
Explanation
Solution
In an anther, cells of endothecium develops fibrous thickening from the inner tangential walls towards the outer wall. Due to hygroscopic nature, endothecium helps in dispersal of microspores. Some endothecium cells, opposite the partition between two sporangia, become thin-walled and constitute the stomium, the site through which pollen grains are released during dehiscence.
