Options

  1. A24
  2. B12
  3. C4
  4. D8

Correct answer

B. 12

Step-by-step solution

The root cell of flowering plant is diploid (2n=24)(2 n=24) while the gamete is haploid therefore, the number of chromosomes becomes 12 in the gamete. The cells of stem, leaf and somatic cells of flower are diploid, therefore, they contain the chromosome number 2n=242 n=24.
