For the ancestors of land plants, supplying water to all cells of the organism would have been possible because

A) algae have vascular tissue that transports water and nutrients to all parts of the organism.
B) water would simply diffuse into the cells from the surrounding environment.
C) the circulatory system of algae evolved early in the history of life.
D) algae take water in through root-like cilia that move water into the cells.
E) algae have specialized structures called desmosomes that move water into the cells.
