angiosperm fertilization involves the so called "double fertilization" which is absent in gymnosperms. In angiosperms the secondary nucleus (formed from fusion of two polar cell nuclei) gets fertilized by the second male gamete along with fertilization of the egg cell of the embryo sac. The fertilization of the egg cell results in the formation of zygote whereas the fertilization of the secondary nucleus results in the formation of PEN (primary endosperm nucleus).PEN develops into endosperm while zygote into embryo. Perisperm provides the necessary nourishment to the developing embryo.

Alternation of generations is the same in all plants in the sense that during sexual reproduction gametophytic generation alters with the sporophytic generation. In angiosperms and gymnosperms the only difference is the presence of embryo sac in the ovule in place of archegonium in gymnosperms. Also double fertilization takes place in angiosperms to have sporophytic endosperm, which remains gametophytic in gymnosperms.
Pollination is a proces of dispersing pollen grains to stigma and the fertilization is the followed proces of pollination.
Pollination is the spreading of pollen from the male to the female part of a flower. Fertilization is the sperm and egg joining to form a zygote and occurs in animals.
While they both produce seeds, gymnosperms and angiosperms differ with respect to the location of seed development, and their flowering.Gymnosperms; naked seeds. Referring to the unenclosed condition of the seeds, as when they are produced they are found naked on the scales of a cone.Angiosperms; flowering plants. Referring to the use of flowers, which contains a carpel as the basic unit of the female reproductive organ.Refer to the related links:
Pollination occurs when pollen reaches the pistil (female parts) of the flower. Fertilization occurs when the sperm cells of the flower fuses with the egg. Germination happens when the conditions are right the plant embryo germinates and begins to develop into a young plant. It is the only stage that does not include fertilization. Pollination is the first step fertilization the second and germination the third and final step.
The difference between gymnosperms and angiosperms is that gymnosperms develop cones as their seed to use in the fertilization process, and angiosperms produce flowers and fruits as their seed to use in the fertilization process.

In angiosperm seeds are enclosed inside the ovary whereas in gymnosperm seeds are naked (i. e. born on megasporophyll) Gymnosperms have archegonium for egg whereas in angiosperms it is replaced by an embryo sac.

pollination means:when pollen lands on a flower stigma. fertilization means:when a male cell joins with a flower cell.
angiosperms Produce Flowers and the other one produces cones this was answerd by a student at ms.137 Q NY school

without fertilization the plant will not grow to it's full extent, without pollination the plant will not produce any fruit/ veggies.
Fertilization. Its the same as sexual reproduction. A big difference is that most plants can self pollinate where as most animals cannot be the male and the female at the same time.
One is a seedless vascular plant that reproduces with spermataphores that need a somewhat water milieu to swim to the site of conception. Ferns. Gymnosperms are seed bearing vascular plants that have a two sex reproductive system somewhat similar, but not as complex as angiosperms.
