Question

WHAT IS POLYNATION? WHAT IS STIGMA?
​

Answer 1

Explanation:

Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky. ... To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination.

Answer 2

Answer:

Pollination means transfer or pollen grains from the anther of a stamen to the stigma of a pistol. It can be of two types:

1. Cross pollination.

2. Self pollination.

Stigma is the uppermost part of the female reproductive system of a flower. It allows the entry of pollen grains to the ovary where it fuses with the ovules and forms zygote.
