Define different branches of Biology.

In order to study all the aspects of life, major divisions of biology arc further divided into different branches as defined below: (i) Morphology This branch deals with the study of form and structure of living organisms. (ii) Anatomy: The study of internal structures is called anatomy. (iii) Histology The microscopic study of tissues is called histology. (iv) Cell biology The study of structures and functions of cells and cell organelles is called cell biology. This branch also deals with the study of cell division. (v) Physiology This branch deals with the study of the functions of different parts of living organisms. (vi) Embryology It is the study of the development of an embryo to a new individual. (vii) Taxonomy It is the study of the naming and classification of organisms into groups and subgroups. (viii) Genetics The study of genes and their role in inheritance is called genetics. Inheritance means the transmission of characters from one generation to the other. (ix) Paleontology It is the study of fossils, which are the remains of extinct organisms. (x) Environmental Biology It deals with the study of the interactions between the organisms and their environment.
