POLLINATION For things to grow and flourish an interaction between the male and the female species must take place. In the human race, this interaction is called sexual intercourse. In the plant world this is most commonly known as pollination. Plants pollinate many ways; their pollen (yellowish powder on the inside of the flower) can be spread by insects (bees in particular), or through the blowing of the wind.

Pollination is a process involving the blooms of a plant. These blooms or flowers act as the plants' primary pollen source; without a flower the pollination process would not take place.

Another critical part in the pollination process is that the plant needs a pollination vector. A plication vector is an agent which carries the pollen. An example of a pollination vector would be a honey bee.

The plant species is divided into two pollination categories. A plant is either an Angiosperm or a Gymnosperm. A Gymnosperm is a spore bearing plant, which uses the wind as a method of pollination. The wind picks up the plants' spores and drops it in another plants droplets. These droplets are located in the flower, on it's naked ovules. For this process to work there has o be plenty of "receiver" down wind.

Wind pollination can work for an Angiosperm plant as well. There is only one restriction. The plant has to be a monoculture (all of the same species). These plants produce a grain which can only be carried by wind. Grasses are a good example of Angiosperm pollination. The pollen seed in grasses is very dry and travels long distances, creating a vast spreading effect.

Pollination is the most important part in a plants life cycle. Plants provide oxygen, collect nitrogen, house insects and provide aesthetic beauty. If plants did not...
