Question

During microsporogenesis, meiosis occurs in

• A. endothecium
• B. microspore mother cells
• C. microspore tetrads
• D. pollen grains

Answer 1

Answer: (B)

microspore mother cells

Answer 2

Microsporogenesis is the formation of microspores in the form of tetrads, which later separate and are called pollen grains. Microspore mother cell $(2n)$ undergoes meiosis for the formation of haploid pollen grains formed first in the form of spore tetrads.
