Question

After culturing the anther of a plant, a few diploid plants were got along with haploid plants. Which of the following parts might have given rise to diploid plants?

• A. Vegetative cell of pollen
• B. Generative cell of pollen
• C. Intine of pollen wall
• D. Cells of anther wall

Answer 1

Answer: (D)

When the anther is used as the explant material for the cultivation of new plants by the tissue culture technique, then there are some plants which are developed as haploid and the other plants are developed as the diploid plants. There are different types of tissues which are present in the anther. The pollen grains and the respective cells like the vegetative cell and generative cell will give rise to the plants which are haploid because they are formed through spermatogenesis. The other cells like the cells of anther wall, endothecium, middle layers are diploid in nature and give rise to diploid plants.

Thus, the correct answer is option B.
