Jul , &#;&#;Pollination occurs when the pollinator moves the pollen from the male plant to the female. The pollen acts as the plant-equivalent of sperm, fertilizing the female for reproduction as well as fruit and seed production. Some plants are self-pollinating, meaning that they can fertilize themselves. Many plants, however, are cross-pollinating ...

What is Pollination? At the most basic level, pollination is the way plants achieve fertilization and genetic diversity. Pollination process occurs when pollen grains from the male part of one flower (anther) are transferred to the female part (stigma) of another flower. Once pollination occurs, the fertilized flowers produce seeds,


Over the past years, the amount of crops that depend on pollinators (i.e. fruit, vegetables, seeds, nuts and oilseeds) has tripled. Bees play an important role in relation to the scope of agricultural production. Effective pollination increases the amount of agricultural produce, improves their quality and enhances plants resistance to pests.


The Importance of Bees: Pollination. The most important thing that bees do is pollinate. Pollination is needed for plants to reproduce, and so many plants depend on bees or other insects as pollinators. When a bee collects nectar and pollen from the flower of a plant, some pollen from the stamensthe male reproductive organ of the flower ...

Process of Pollination. The process of pollination begins when the pollen grains from the respective flowers lands on the stigma and form a pollen tube with the style length, which connects both the stigma and ovary. After the completion of the pollen tube, the pollen grain starts transmitting sperm cells from the grain to the ovary.

Pollinating insects also play a critical role in maintaining natural plant communities and ensuring production of seeds in most flowering plants. Pollination is the transfer of pollen from the male parts of a flower to the female parts of a flower of the same species, which results in fertilization of plant ovaries and the production of seeds.


Research has traditionally explored the role of chemical pigments and volatile organic compounds as cues for pollinators, but recent reports have demonstrated the importance of physical and structural means of pollinator attraction.

Uses and dangers of electrostatics. There are many industrial uses of static electricity. These make use of both repulsion of like charges, and attraction of opposite charges.


Pollination and seed dispersal are great examples to illustrate the interdependence between living organisms, such as animals and plants, in nature. All plants need pollination to make seeds and fruits. Pollination occurs when pollen gets carried from the male part of one plant's flower to the female parts of a new flower (Figure ).
