Question

The innermost layer of anther wall which surrounds the sporogenous tissue
Has a-cellulosic fibrous bands in its cells
O Helps in dehiscence of anther also
Nourishes the developing pollen grains
O Has cells which lack nucleus​

Answer 1

Answer:

The innermost layer of anther wall which surrounds the sporogenous tissue is called as Tapetum. It nourishes the developing pollen grains.

Explanation:

What is tapetum:

• The sporogenous tissue is totally surrounded by tapetum, which is the deepest layer.
• Tapetum cells have a thick cytoplasm and frequently have several nuclei.
• Tapetum nourishes the developing pollen grains.

What helps in dehiscence of anther:

• Endothecium is a layer of the anther wall that aids in anther dehiscence.
• Endothecium cells mature into fibrous thickenings that radiate from the inner tangential walls.
• Alpha cellulosic fibrous bands and lignin traces make up these thickenings.
• Because these thickenings are hygroscopic, they aid in the dehiscence of anthers.
