Question

Which of the following is correct regarding microsporogenesis in an anther?

• A. Each microsporogenesis involves one meiosis
• B. Only 1 microspore mother cell differentiates in one pollen sac.
• C. It only consumes tapetum and not endothecium.
• D. Microspore tetrad is always trihedral.

Answer 1

Answer: (A)

Microsporogenesis is the process of formation of microspores from microspore mother cells by meiosis. The microspore then forms pollen grain which is a male gametophyte. Pollen grain then undergoes mitosis to form male gamete and the process is known as microgametogenesis.
