Question

The following is the diagram of T.S. of Anther. Identify the parts labelled A, B, 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

Answer: (A)

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.
