An majority of the angiosperm anther is bilobed and every lobe has two theca so in all there are four theca. However, in Malvaceae family, anther is monothecous and has two theca only.
The innermost layer of the microsporangia is tapetum and it nourishes the developing pollen grains.
The distal end i.e. the farther end of the filament is attached to the stamen.
Pollen grains of the same species will have same morphology.
