Plant pollinators
We can say that directly or indirectly, plant pollinators are responsible for the survival of many plant species that produce offspring with the help of pollination.
Morphological adaptation:
From centuries, flowers have produced a very fascinating relationship with different pollinators. Some flowers set the time of their pollination in such a way that more and more visitors like bees, moths, butterflies and other insects are attracted. These insects then carry pollen grain to the female part. Once pollen grain successfully reaches their destination, fertilization takes place. This fertilization then result in fruit and seed production. However, the plants that attract more and more visitors reduce chances of self-pollination to a very lower extent.
To attract visitors flowers use tricks like scent, color and form. Butterflies, moths, bees and other insects are attracted towards plant due to their refreshing scent or fascinating colors and shapes.
Wind:
Wind is also another very important pollinator. There are various species of plants that are pollinated by wind. The flowers on the plants that are pollinated by wind appear in early spring when leaves are staring to appear. This strategy prevents any loss of pollen due to interference of leaves. Hence, as a result, more exposure is given and pollen grains can easily reach female flower and make the pollination successful. Mostly flowers of wind pollinated plants produce large amounts of pollen grains and are present close to one another.
This close production of the plants is to ensure that female flower get immense chances of getting pollen grain. As there are so many male plants in locality and they are producing high number of pollen grains there are more chances of successful pollination and in result successful fertilization. However, other than interference by pollinators, some other factors might influence production of fruit. These factors include draught, extreme weather conditions etc.
Water:
The only plants that use water as a pollinator are aquatic plants. These plants release there seeds within water.
Animals:
The pollen that is transferred with the help of animals is sticky. Due to its sticky structure, it attaches to the fur, face or legs of the animals and is transferred to its destination. Both of the partners is this mutual collaboration benefit from one another. Animals transfer pollen grain from one part of the plant to another and ensure pollination as well as fertilization in plants. Whereas plants in turn offer them nectar and food. Both of them are evolving with the passage of time.
