Question

In a flower, the male gametes are formed from

• A. Vegetative nucleus
• B. Generative nucleus
• C. Primary endosperm nucleus
• D. Synergid nucleus

Answer 1

The correct option is B Generative nucleus

The pollen grain has two nuclei called as tube nucleus and the generative nucleus. After the process of pollination, pollen tube is germinated by pollen grains which travel through the stigma and style and reaches the ovules in the ovary and then the generative nucleus divides to form two male gametes in which one fuses with egg and other with polar nuclei.

So, the correct answer is option B.
