There are two types of pollination.
1. Abiotic
2. Biotic
1: Abiotic Pollination
It refers to the situations where pollination is mediated without the involvement of the organisms. Anemophily and Hydrophily are the most form of abiotic pollination. Anemophily is pollination by wind. This form of pollination is predominant in grasses and conifers. Hydrophily is pollination by water, and occurs in some gymnosperm. The best example is Cycadales. Mainly abiotically pollinated species, 98 % are anemophilous and 2% hydrophilous.
In this pollination required pollinators due to that organisms that carry or move the pollen grains from the anther to receptive part of the carpel or pistil. This is known as biotic pollination. There are roughly 200,00 varieties of animal pollinators.In which most are insects.Pollination by insects is called Entomophily. Insects are often occurs on plants that have developed colored petals and a strong scent to attract insects such as, bees, wasps, beetles, flies, moths and butterflies. and some of them are birds and bats.
