What is Branches of Biology.

Branches of Biology.

Biology is a vast subject. Therefore, biology is divided in to many branches for study. Some of these branches are:

Embryology.

The study of the development of an embryo till it is hatched (slayer in) or borne is called embryology.

Physiology.

The study of functions of the different parts of an organism is called physiology.

Morphology.

The study of form (surface) and structure of the different parts of the organisms is called morphology.

Anatomy.

The study of the internal organs (+LL) of an organism is called anatomy. It is also. called internal morphology, For example study of eye,

Histology.

The study of the tissues of an organism is called histology. For example, study of iris, lens and cornea of eye,

Tissues.

A group of similar cells, having same origin and performing the same function is called tissue,

Paleontology.

The study of fossils and their relation with the evolution is called paleontology

Fossil.

The dead remains of the living organisms or their imprints  preserved in the rocks are called fossil.

Evolution.

The development of more advanced and complex organisms from pre-existing ( simple (primitive) ( int) is called evolution.

Genetics.

The study of transfer of the hereditary character from the parents to the offspring is called genetics.

Zoogeography.

The study of the distribution of the animals in different regions of the earth is called zoogeography.

Molecular Biology.

The study of the molecular structure of the organisms, their cells or the organelles of the cells is called Molecular biology.

Environmental Biology or Ecology.

The study of the relationship between the organisms and their environment is called Environmental biology. The interactions between the organisms and their inorganic and organic environments are studied in this branch. The relation of these interactions with the human activities is also studied.

Microbiology.

The study of the micro organisms is called Microbiology. For example study of Bacteria, Viruses, Protozoa, microscopic algae and fungi.

Freshwater Biology.

The study of the organisms living in freshwater bodies and the physical and chemical parameters of these bodies is called freshwater biology, The fresh water bodies are like rivers, lakes etc.

Marine Biology.

The study of marine life and physical and chemical parameters of sea or oceans is called Marine biology.

Parasitology.

The study of the parasites is called parasitology. The structure, mode of transmission ( life histories and host-parasite relationships are studied in this branch.

Human Biology.

The study of man is called Human Biology, The structure, function, histology, anatomy, morphology, evolution, genetics, cell biology and ecology of human being-are studied in this branch,

Social Biology.

The study of the social behaviour and communal  life of human being is called social biology.

Biotechnology.

The use of living organisms, their systems or processes in the manufacture and services industries ids called Biotechnology.
