Plants invaded the land sometime during the Paleozoic era. In order to evolve and thrive on land, plants had to

A) develop photosynthetic pigments and mechanisms for transporting water and minerals to aerial parts.
B) develop starch for carbohydrate storage and mechanisms for transporting water and minerals to aerial parts.
C) develop physical support structures and mechanisms for gamete dispersal.
D) develop photosynthetic pigments that are not dependent on an aqueous environment and develop starch for carbohydrate storage.
E) alternate generations and develop physical support structures.
