Question

What are out Breeding devices

Answer 1

→Most of the flowering plants known is hermaphrodite in nature.

→And that's why there's chances that pollen grains sticks to the stigma of the same flower.

→This means self pollination.

→And drawback of self pollination is inbreeding depression.

→So,that's why some plants have developed devices or mechanism to promote cross pollination and prevent self pollination.

→For example :-

1) Stigma and anther are placed at different positions.

2)Self incompatibility etc.

Answer 2

Pollen-Pistil Interaction & Outbreeding Devices. Pollination is the process which plants depend on to transfer pollen grains from anther to stigma/pistil. It can be either cross pollination or self pollination. Most of the plants are bisexual/ hermaphrodite which promote self pollination.
