Question

Pollen tube carries ___________ gamete (male/female).

Answer 1

Pollination:

1. The transfer of pollen grains from the anthers of a flower to the stigma of a flower is called pollination.
2. Immediately after pollination, i.e., when the pollen grains reach stigma, a pollen tube arises from each pollen grain.
3. Each pollen tube carries the male gametes.
4. The pollen tube elongates and grows through the style to reach the ovary where the ovule is present.
5. The pollen tube enters the ovule and releases the male gametes.
6. The male gamete fuses with the egg or female gamete and forms a single cell called a zygote.

Final answer: Pollen tube carries male gamete.
