Endothecium

Vedclass · Answer

(B) The wall of the microsporangium consists of four layers: the epidermis, endothecium, middle layers, and tapetum.$1$. The $Epidermis$ is the outermost protective layer.$2$. The $Endothecium$ develops fibrous thickenings of $\alpha$-cellulose at maturity, which helps in the dehiscence of anthers to release pollen grains. Due to these fibrous thickenings, it is often referred to as the fibrous layer.$3$. The $Middle$ $layers$ are ephemeral and provide nourishment.$4$. The $Tapetum$ is the innermost layer that provides nutrition to the developing pollen grains.Therefore, the correct answer is $Endothecium$.

Which layer of the microsporangium is also known as the fibrous layer?
