This method helps the plants to increase their population.

They are,

Self pollination.

Cross pollination.

Pollination means transfer of pollen from another and stigma, so it is a best way.

Ramanuj said: (Aug 18, 2015)  
Pollination is transfer of pollen from male part i.e another to female part i.e. stigma. Insects, birds, animals, wind etc are sources through which pollination occurs.

Transfer of pollen from anther to stigma is the right answer because without transfer of pollen from anther to stigma the pollination can not occur.

Pollination has two ways which are:

1. Self pollination.
2. Cross pollination.

Because pollen is male part and stigma is female part of plant. So transfer to many source.

Since there are two types of pollination. i.e in self pollination in a condition of protandry the pollination. Is done inside the flower without no external agent?

Yes, without external agent pollination is impossible.

Arathi.S.V said: (Mar 2, 2019)  
Pollination is the process of transferring pollen grains from anther to stigma of the flower. If the pollen grains of a flower is transferred to the stigma of the same flower, then it is called self-pollination. If the pollen grain of a flower is transferred to the stigma of another flower of the same species of the plant then it is called cross-pollination.
