During self pollination the plant does the reproduction process by itselfbut during cross pollination..insects sit on one flower suck nectar and fly off to some other flower...the next flower they sit the pollen grains which were stuck on their feet get transferred to the new flower and pollination is complete!1

Hi there!
Let us know some facts about insects first :)
♦ Insects are the abundant animals on the earth at present.
♦ They are the most dominant over all other terrestrial animals in numbers, and occur everywhere.
♦ They ancient group of animals in the world.
♦ They are found throughout the world in all bio geographical regions and ecological zones.
!! CONTRIBUTION OF INSECTS TO BIODIVERSITY !!
The role of insects in maintaining the cycle of nutrients, soil regeneration and protection, pollination of phanerogamic plants as well as natural regulation of pests.
About 75% of all crop plant species are pollinated by insects, while many flowering plants are capable of self-fertilization, the majority of them depend on pollination of their flowers from those of another plant in order to set fertile seed and maintain genetic diversity.
The mutual advantage of this association has evolved many pollination mechanisms (very complicated and highly specific) and has leads to many adaptations in structure, functions and behavior of both insects and plants.
Hope it helps! :D
