Let us make an in-depth study of the fertilization, embryology and seed of angiosperms. It is possible to get three types of seeds among both dicotyledons and monocotyledons according to the final equilibrium. They are: (1) Exalbuminous Seeds (2) Albuminous Seeds and (3) Perisperm Seeds. Pollination ends in a copious dusting of the stigma surface with pollen grains (Fig. 414). [...]
In this article, we propose to discuss about the life cycle of angiosperms with diagram. With the development of the seed, the life cycle of Angiosperms comes to a close. If we now trace the life-history (Fig. 432) we shall find a regular alternation of generations as in most groups of plants. The plant is a sporophyte with 2n or [...]
