Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub
State whether the following statements are true or false regarding androecium.
I. The anther of all angiosperms has four theca.
II. The outermost layer of the microsporangium is the tapetum.
III. The distal end of the filament is attached to the stamen.
IV. Pollen grains of the same species differ from each other in their morphologies.
Options:
Answer:
Solution:
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.
