graduate programs for biology majors

Branches of biology: Based one the type of organism, biology is divided into two branches - Botany and zoology. Grounded on the aspect of consideration, there are also two other divisions of biology - physical biology and applied biology. Physical biology: In the field of physical biology, theoretical concepts are usually discussed. The following subjects are the general fields of its condemn. Morphology: The field deals with the form and structure of organisms. It is usually divide into two branches - external and morphology. The external description of the body is called external morphology and the internal description of of the body is called internal morphology. Taxonomy: classification of organisms and the principles related to this task are discussed in the field. Physiology: This branch of biology deals with the biochemical activities of different organs of organisms. Besides, detailed description of all the physiological process of organisms is found in it. Histology: The microscopic structure, arrangement and function of plant and animal tissues are studied in this subject. Embryology: The branch of biology discusses the development of embryo of organisms. Cytology: The structure, function and division of an individual cell in a body of organisms are studied in this field of biology. Genetics: The branch of biology deals with genes and heredity. Evolution: The gradual development of life and organisms and their environment. Endocrinology: The field of science deals with the study of endocrine glands and hormones secreted by them in a body of organisms. Bio geography: The branch of biology studies the geographical distribution of organisms, past and present, throughout the landscape of planet earth including the knowledge of classifying bio-geographical patters.
