A biologist studies the origin, development, function, and structure of animal and plant life. The word biology comes from the Greek word bios, which means "mode of life." Biology covers a broad area within the life sciences, a biologist studies everything from algae, to plants, to invertebrate animals, to mammals, to one-celled animals like amoebas, to slime moulds. Every living thing lives in a habitat or environment that is suited to the way the organism lives. There are many different kinds of living organisms because there are many different kinds of environments.
A biologist usually specializes in one area and is named by that speciality. However, many of these specialities share many of the same characteristics yet maintain their own special components.
