Work Tasks

PHYSIOLOGISTS study the life functions of plants and animals, both in the whole organism and at the cellular and molecular level. Some physiologists study the life processes of plants to learn more about organic responses to air and water pollution. Physiologists often specialize in growth, reproduction, respiration, circulation, movement, photosynthesis, and other life functions of plants and animals, or in the physiology of a certain area or system of the organism. Physiologists perform experiments to determine the effects of internal and external environmental factors on life processes and functions.

Entry Requirements

For PHYSIOLOGISTS, a Ph.D. generally is required for college teaching, independent research, and for advancement to administrative positions. A master's degree is sufficient for some jobs in applied research and for jobs in management, inspection, sales, and service. A bachelor's degree is adequate for some non-research jobs. Undergraduate biological science majors usually study chemistry, biology, and allied disciplines such as mathematics, physics, and computer science. Those interested in studying the environment should take courses in environmental studies.
