The Major Difference Between Pollination And Fertilization is that Pollination is the deposition of pollen grains on the stigma of the flower and is a physical process while Fertilization is the fusion of haploid male and female gametes, forming a diploid zygote and is a cellular, genetic and biochemical process.
Pollination is the process of the transfer of pollen grains from male to female parts in seed plants. It is the transfer of pollen grains from the anther to the stigma of the ovary.
Fertilization is a process that involves the union of the male gamete or sperm with the female gamete or ovum to produce a zygote. This is essential for sexual reproduction. A zygote gets genetic materials and characters from both parents.
