Question

Reductional division takes place in _____________ during microsporogenesis.

• A. microspores
• B. microspore mother cell
• C. endothecium
• D. tapetum

Answer 1

The correct option is B microspore mother cell

In meiosis, the chromosome number is reduced to half. Thus meiosis is also known as reductional division. If the parent body is diploid, in order to produce gametes, meiosis takes place inside the reproductive organs. During the formation of microspores (microsporogenesis), chromosome number in the microspore is reduced to half.

Thus reductional division takes place in the microspore mother cell as it is a diploid cell.

While endothecium and tapetum are wall layers in a sac-like structure called microsporangia in an anther and do not give rise to the microspores.
