Question

Where does pollination occur?

Answer 1

Pollen grains from one flower's male part (anther) are transported to the female part (stigma) of another flower during pollination. The fertilised blooms generate seeds after pollination, allowing the linked plant to reproduce and/or produce fruit.

Complete answer:
Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species takes place. It occurs on the stigma (Female reproductive organ) of a flower. It occurs in two different types namely self pollination and cross pollination. Self pollination is one that occurs either within the same flower or between two flowers on the same plant. Cross pollination occurs between two flowers on different plants of the same species. For cross pollination to take place, an agent has to be available. These agents can be insects, wind or water.
After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begin to grow in a tube. This tube is called the pollen tube. The pollen tube lengthens through the style and enters the ovule in the ovary. There, it releases its male cells which fuse with the female cells of the ovule to produce a zygote. The ovule containing the fertilized cell develops into a seed. The covering of the ovule gives rise to the seed coat and the ovary containing the seeds develops into a fruit.
Pollination is the transfer of pollen from an anther to a receptive stigma.It occurs with the help of biotic agents like flies, insects, bats, molluscs, birds, lizards (in flax), elephants (Rafflesia), etc. It also occurs via abiotic agents like wind, water, etc. Animals such as insects, birds, and bats, as well as water, wind, and even plants themselves, when self-pollination happens within a closed bloom, are pollinating agents.

So we can say that pollination occurs on the stigma (Female reproductive organ) of a flower.

Note:-
The pollinator's habitat is determined by the pollinator's life cycle stage. Bees, for example, can build their nests out of leaves, dirt, sand, plant resins, and even abandoned snail shells, but many butterfly larvae live and feed on a single plant.
