Question

The following is the diagram of TS of anther. Identify the parts labelled as A, B and C.

• A. A- Connective, B- Endothecium, C-Pollen grain
• B. A- Endothecium, B- Connective, C- Pollen grain
• C. A- Pollen grain, B- Connective, C- Endothecium
• D. A- Endothecium, B- Pollen grain, C- Connective

Answer 1

The correct option is A A- Connective, B- Endothecium, C-Pollen grain

Stamen is the male reproductive whorl in a flower composed of anther and filament. A filament is a stalk that supports the anther. The anther lobes are connected by a connective that is an extension of the filament.

A is the connective.

Endothecium is the middle layer out of the three layers in anther that helps in anther dehiscence and pollen grain dispersal.

B is endothecium.

Pollen grain is the male gametophyte that has the male gametes.

c is the pollen grain.

Thus the correct answer is option A.
