|
Pollination = Fertilization whereas seed dispersal is a means of getting the already fertilized egg (seed) as far away from the parent plant as possible.
|
|
|
Fertilization only happens in seedless plants.
|
|
|
Only flowering seed plants have methods for both pollination and seed dispersal.
|
|
|
Seed plants have seed dispersal whereas seedless plants have pollination.

Detailed explanation-1: -Pollination is the transfer of pollen from an anther to a receptive stigma. Meanwhile fertilization is when the pollen grain germinates to produce a pollen tube that carries down the two male nuclei. Seed dispersal is the scattering of seeds using other animals or mother nature (wind) to scatter the seeds.
Detailed explanation-2: -Pollination is the transfer of pollen grains from an anther to a stigma. Pollen can be transferred by an animal or by the wind. Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.
Detailed explanation-3: -Pollination occurs when anther of the stamen reaches the stigma of the ovary. Fertilization occurs when sperm and ovum fuse. Pollination is a physical process. Fertilization is a biochemical process and has a genetic basis.
Detailed explanation-4: -What is Seed Dispersal? Seed Dispersal is an adaptive mechanism in all seed-bearing plants, participating in the movement or transport of seeds away from their parent plant to ensure the germination and survival of some of the seeds to adult plants.
