What is Pollination and its Types

Pollination and its Types

 

The transfer of pollen grains from anthers of a stamen to the stigma of a carpel of same kind of flower is called pollination. There are two types of pollination:

 

Self-Pollination:

 

The transfer of pollen in the same flower or between two flowers of same plant is called self-pollination.

 

Cross-Pollination:

 

The transfer of pollen from one plant to another plant of same species is called cross- pollination. This kind of pollination takes place through wind, water or by insects.

 

So, the Grand Rapids Public Library in Michigan donated 100 new readers Nook to four public schools. They decided to distribute the books among the students of the sixth and seventh grades. The goal is simple: to get children to read more, and at the same time to introduce them to new technologies from a young age. Since the books have the ability to access the Internet, children are also encouraged to download books online and use other browser features. In this case, all actions for students will be paid for by the donor. The books cost the library about $ 20,000 and the money was donated by the Grand Rapids Community Foundation.
