$<b>$
♣ The pollination takes place within the single flower.

♣ Pollengrains from the pollen tube moves to the stigma of the same flower.

Answer 2

Difference between self and cross pollination

Explanation:

• self-pollination:

    2 flowers don't rely upon different Agencies for impregnation.

     3 spore grains area unit created in a tiny variety

• cross-pollination

   1 it happens between 2 flowers on totally different plants of identical species.

   2 agents like insects water and wind area unit needed for impregnation.

   3 spore grains area unit created in a sizable amount
