The Basic Premise and the Areas of Specialization
Biologists study the origin, development, structure, and function of plant and animal life. The word biology comes from the Greek word bios, which means "mode of life." Biologists usually specialize in one area and are recognized and named by that specialty. This role encompasses a large number of subfields and specializations, from Microbiology to Biochemistry to Wildlife Biology.
Wildlife Biologists concentrate on the traits and habitats of wild animals. Plant Biologists, or Botanists, study how plants function and evolve. Scientists who specialize in Human Biology help people lead healthier lives. As Molecular Biologists, they research medical drugs and create strategies for environmental protection. Biologists also develop public health campaigns to raise awareness of and prevent deadly diseases.
Bacteriologists and Virologists research bacteria and viruses that affect people, while Clinical Microbiologists discover microorganisms that can cure human disease. Immunologists specialize in the immune system defenses of the human body. In many cases, Biologists are recognized according to the kind of organism that they study. For example, Biologists who study animals are often known as Zoologists. Biologists who specialize in plants are called Botanists. Those who work with microscopic forms of plant and animal life, such as bacteria, fungi, and viruses, are known as Microbiologists.
Anatomists study the structure of living things, ranging from single-celled plants and animals to human beings and redwood trees. Physiologists specialize in the study of the life functions of plants and animals. These functions include growth, respiration, and reproduction. Geneticists study heredity and how traits, or inherited characteristics, vary in all forms of life. Pathologists concentrate on the effects of diseases on the cells, tissues, and organs of plants and animals.
Nutritionists study how food is used and changed into energy. They examine how living tissue is built and repaired by its use of vitamins, minerals, proteins, and other nutrients. Pharmacologists study the effects of drugs and other substances, such as poisons and dusts, on living organisms.
Biology +
Some scientists work in areas that combine other sciences with Biology. For example, Biochemists specialize in the chemistry of living things. Biophysicists concentrate on the atomic structure and the electrical and mechanical energy of cells and organisms. Ecologists are life scientists who study the relationship of plants and animals to their environment. Other life scientists specialize in the organisms in one kind of environment. Marine Biologists, for example, study organisms that live in the ocean.
One Specialism - Varied Avenues of Employment
Some Geneticists are hired to develop new breeds of animals, such as chickens, that can provide better food for people. Other Geneticists teach Biology and genetics to college students. They may also work for hospitals where they counsel people to help them understand how likely they are to pass on hereditary diseases.
