The study of certain types of algae lends insight into the evolution of plants. Such study has shown that green algae and plants are closely related and thus share an evolutionary history. Green algae and plants share many characteristics, including the composition of their chlorophyll pigments and their cell walls. Although green algae have no true roots, stems, or leaves, these traits are also characteristic of the Bryophyta, a group of plants that includes mosses and liverworts. The simplest algae are single-celled organisms that float about in the water and absorb food through their cell walls.
They sometimes accumulate on the sides of glass aquariums. Although usually found in water and moist places, some species of algae inhabit the soil and can survive dry conditions for a long time.

They are prepared by injecting bacterial toxins into live animals. The blood is later collected and the serum is separated from it by chemical means. Antitoxins act more quickly than vaccines, but the protection usually lasts no more than a few weeks or months. Vaccines, however, protect for a year or longer. Some kinds of microorganisms secrete substances called antibiotics that can destroy other microbes. Penicillin, the bestknown antibiotic, is the product of a mold. Bacitracin and polymyxin are made by bacteria.
