What is the difference between pollination and fertilization in angiosperm?
Pollination is the transfer of pollen from the anther to the stigma, while fertilization is the fusion of the male gamete with the female gamete to form a zygote. In angiosperms, pollination leads to the transfer of pollen to the stigma, followed by fertilization of the egg cell within the ovule to produce a seed.
Describe what happens between pollination and seed formation in angiosperms?
In angiosperms, after pollination, pollen grains land on the stigma of a flower, where they germinate and form a pollen tube that travels down the style to the ovary. During this process, sperm cells from the pollen tube fertilize the ovule, leading to the formation of a zygote. The zygote develops into an embryo, while surrounding tissues form the seed coat and endosperm, which provides nourishment. Once maturation is complete, the seed is formed, ready for dispersal and eventual germination.
What happens once the pollen lands on the stigma?
Pollination
What happens to gymnosperms during pollination?
Gymnosperms do not produce flowers (as opposed to angiosperms), so there is nothing to attract pollinating insects. As a result, they depend on the wind to blow the pollen from the male to the female cones. Pollination can also occur if the male cones are present at the same time and situated above the female cones. In this case self-pollination can occur when the pollen simply falls or blows downward.
What is the difference between pollination and fertilization gymnosperms vs angiosperms?
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.
What happens to pollen grains immediately after pollination?
Pollen germination starts on compatible stigma
Which happens first pollination or fertilation?
Pollination. Fertilization is what occurs after pollination.

What doese pollination mean?
Pollination happens is when the pollen goes into the ovary.
What happens during the processes of cross-pollination and self-pollination?
there is not to big of a differents

When does pollination happens?
Cross pollination happens when the pollen of one flower is placed upon the stigma of another flower, whether of the same varietyor not.
