1.Microbiology--
a study dealing with the structure and existence of microorganisms, which are
tiny life forms such as a bacteria or a virus.
2.Zoology--
which is the study of animal life
3.Botany--
which is focused on plant life
4.Physiology--
Study of the vital functions and basic activities of living organisms - cells,
tissues, organs, and organ systems - and their parts, in relation to the whole.
5.Embryology--Study
of the formation and development of organisms from the zygote, or fertilised
egg. Confined mainly to multi-celled organisms.
6.Taxonomy--Hierarchical
classification of natural organisms indicative of their structures and
differences.
7.Genetics--Study
of inheritance and variation in organisms, and mechanisms by which these
operate; causes of similarities and differences among related individuals.
8.Ecology--Study
of relationships between organisms and their environment; the interactions of
individuals within groups and with their suroundings.
9.Morphology--The
study of the shapes of plants and animals.
10.Molecular
Biology--Study of chemical processes at the level of large organic molecules
such as proteins and nucleic acids.
11.Biochemistry--Study
of the chemical processes within living systems as a whole.
12.Bioarchaeology--The
systematic study of past life by the recovery and examination of remaining
material evidence, such as bones, petrified animal or plan imprints, etc.
13.Biogeochemistry--The
study of the relationship between the geochemistry of a region and the animal
and plant life in that region.
14.Cytology--
Study of cells.
15.Orinthology--
Study of birds.
16.
homology--That relation between parts which results from their development from
corresponding embryonic parts, either in different animals, as in the case of
the arm of man, the foreleg of a quadruped, and the wing of a bird; or in the
same individual, as in the case of the fore and hind legs in quadrupeds, and
the segments or rings and their appendages of which the body of a worm, a
centipede, &c., is composed. The latter is called serial homology. The
parts which stand in such a relation to each other are said to be homologous,
and one such part or organ is called the homologue of the other. In different
plants the parts of the flower are homologous, and in general these parts are
regarded as homologous with leaves.
17.Herpetology-
The study of reptiles and amphibians.
18.
Histology- Study of tissues.
19.
Osteology: study of bones.
20.Gynecology:Study
of the health of the female organs of reproduction and diseases thereof.
