1.1.1 divisions and branches of biology.
00:02 - There are three major divisions of biology which study the different aspects of the lives of the major groups of organisms.

00:09 - Zoology, This division of biology deals with the study of animals.

00:14 - Botany, This division of biology deals with the study of plants.

00:20 - Microbiology, This division of biology deals with the study of microorganisms such as bacteria etc.
In order to study all the aspects of life, these divisions are further divided into different branches
as defined below.

00:33 - Morphology : This branch deals with the study of form and structures of living organisms.

00:39 - Molecular Biology Biochemistry deals with the study of the molecules of life, egg, water, proteins, carbohydrates, lipids and nucleic acids.

00:49 - Anatomy, The study of internal structures is called anatomy.

00:53 - Histology, The microscopic study of tissues is called histology.

00:58 - Cell biology, The study of the structures and functions of cells and cell organelles is called cell biology. This branch also deals with the study of cell division.

01:09 - Physiology, This branch deals with the study of the functions of different parts of living organisms.

01:15 - Genetics, The study of genes and their roles in inheritance is called genetics. Inheritance means the
transmission of characters from one generation to the other.

01:25 - Embryology, It is the study of the development of an embryo to new individual.

01:30 - Taxonomy, It is the study of the naming and classification of organisms into groups and subgroups.

01:37 - Paleontology , It is the study of fossils, which are the remains of extinct organisms.

01:43 - Environmental biology, It deals with the study of the interactions between the organisms and their environment.

01:50 - Socio-biology, This branch deals with the study of social behaviour of the animals that make societies.

01:57 - Parasites are the organisms that take food and shelter from living hosts and, in return,
harm them.

02:03 - Parasitology: This branch deals with the study of parasites.

02:07 - Biotechnology: It deals with the practical application of living organisms to make substances for the welfare of
mankind.

02:15 - Immunology : It is the study of the immune system of animals, which defends the body against invading microbes.

02:22 - Entomology : It is the study of insects.

02:26 - Pharmacology : It is the study of drugs and their effects on the systems of human body.

02:31 - Human population growth, infectious diseases, addictive drugs and pollution are the major
biological issues today.
