Branches of Biology

Biology is the study of living organisms that include plants, animals and micro-organisms. There are several special branches or disciplines of botany. Basically there are three branches dealing about plants , animals and micro-organisms . They are as follows:

1.Botany- study of plants

2.Zoology-study of animals.

3. Microbiology- Study of microorganisms.

Besides, these three there are other various branches of biology dealing with the study of respective subjects which are as follows:

1.Morphology- It deals with the study of external features of organisms.

2.Anatomy- It is the study of internal structure of organisms as seen by naked eyes.
3.Histology-Study of functions and minute structure of tissues with the help of microscope.
4.Cytology-It deals with the study of structure and functioning of cells and cell organelles.
5.Evolution-Study of origin of life and evolution to modern plants and animals.
6.Embryology- Study of formation of embryo upto hatching or birth.
7. Physiology- Study of life processes in animals and plants.e.g digestion, respiration,excretion, growth etc.
8. Pathology- Study of diseases.
9. Paleontology- Study of plant or animals fossils.
10. Biotechnology- Study of using techniques to modify the organisms and their products for human benefit.
11. Taxonomy- Study of identification, nomenclature and classification of organisms and its principles.
12. Genetic engineering- Study of producing desireable genotypes by synthesis and combination of different genes.
13. Genetics- Study of hereditary characters and their inheritance.
14. Ecology- Study of relationship between living organisms and environment.
15.Biochemistry-Study of chemistry of living organisms.
16.Molecular biology- Study of nature and arrangement of molecules and their interactions. eg structure and functions of DNA, RNA, proteins, fats, hormones etc.
17.Exobiology- Study of possibility of life in outer space.
18. Applied biology- Study of living organisms concerned with welfare and betterment of mankind.
19. Limnology- Study of fresh water and their inhabitants.
20. Cryobiology- Study of effects of life at very low temperature.
21. Phylogency- Study of evolution of a kind or type of an organ.
Besides all these there are also so many branches or disciplines related to both botany and zoology . Some of the branches related to zoology are given as under
