In this article we will discuss about the types and agents of pollination.

Each pollen grain grows and provides two male gametes for fertilisation of an ovule. Depending upon the source of pollen grain, pollination [...]
In this article we will discuss about:- 1. Meaning of Cross-Pollination 2. Advantages and Disadvantages of Cross-Pollination 3. Adaptations. Meaning of Cross-Pollination: If pollen grains are carried to the stigma of a flower of the same species growing on a different plant, it is cross-pollination. All unisexual flowers are cross-pollinated and even the bisexual flowers which, in fact, form the [...]
