Question

Name and differentiate between the two modes of pollination in flowering plants.

Answer 1

Two types of pollination can be found in flowering plants:-

1. Self-pollination
2. Cross-pollination

Differences between the two are given below:-

Self-Pollination	Cross-Pollination
The pollen needs to be transferred from the stamen to the stigma. If this transfer of pollen occurs in the same flower, it is referred to as self-pollination.	The pollen is transferred from one flower to another, it is known as cross-pollination.
It occurs in bisexual flowers.	It occurs in both bisexual and unisexual flowers.
It refers to the transfer of pollen grains from anther to stigma of the same flower or to another flower of the same plant.	It refers to the transfer of pollen grains from anther to stigma of flowers belonging to two different plants.
It is not necessary to use pollinators.	This transfer of pollen from one flower to another is achieved by agents like wind, water or animals.
