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 are the differences between algae and angiosperms?
The difference between algae and angiosperms is angiosperms have true roots,stems and leaves while algae does not. Also angiosperms are flowering plants and algae lives mainly in water.

Distinguish between self-pollination cross-pollination?
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.

Is cross pollination between different types of flowers possible?
No, only cross pollination between plants of the same genus and species
