Angiosperms are the flowering plants (today the most abundant and diverse plants on earth).
Most are terrestrial and all lack locomotion. This poses several problems.

Angiosperm
Any plant that is a member of the class Angiospermae, in which the seeds are enclosed in an ovary. Each member of the class is either a monocotyledon (grasses, tulips) or a dicotyledon (apple, primrose).
