Question

If a gymosperm plant has 24 chromosomes in microspore mother cell. The number of chromosome in its endosperm is ______.

Options

• 24

• 36

• 12

• 48

Answer 1

If a gymosperm plant has 24 chromosomes in microspore mother cell. The number of chromosome in its endosperm is 12.

Explanation:

A microspore mother cell is a diploid cell in plants that undergoes meiosis, resulting in the formation of four microspores. As a result, the diploid chromosome number in a microspore mother cell is 24, i.e. 2n = 24. As gymnosperm endosperm is haploid, the number of chromosomes in the endosperm is 12.
