Embryology of Angiosperms

By Dr. Khursheed Ahmad Ganai | Islamia College of Science and Commerce, Srinagar

Learners enrolled: 432

Embryology of angiosperms is a course which reflects the various events which are met in during the sexual reproduction of angiosperm plants. This course maps the sequence of all important developmental events such as flower formation, development of male and female gametophyte, pollination, pollen-pistil interaction, double fertilization, endosperm development, embryo development, seed and fruit formation, seed dispersal and seed dormancy. This course encompasses all these above mentioned topics which string together into a story explaining how angiosperms bring about the formation of sexual off-springs and how the gametophytic and sporophytic generations alternate in them.
