This document provides an introduction to the field of biology. It defines biology as the study of life and living things. The document then outlines some of the main divisions and branches of biology, including botany, zoology, microbiology, anatomy, histology, genetics, embryology, taxonomy, paleontology, ecology, sociobiology, parasitology, biotechnology, immunology, entomology, pharmacology, biophysics, biochemistry, biomathematics, biogeography, and bioeconomics. Each branch involves the study of different aspects of living organisms, ranging from their internal structures and functions to social behavior, evolution, interactions with environments, and economic applications.

• Bio – means life
• logos – to study / the study
• BIOLOGY – is the study of life / the
study of living things

22. • the study of
functions of
different
parts of
living
organisms.

23. • Genetics –
• the study of genes
and their role in
inheritance.
• Inheritance:
• The transmission of
character from one
generation to the
other.

24. • The study of the development of an
embryo to new individual.

25. TAXONOMY
• Study of the naming and
classification of organisms into
groups and subgroups.

27. Paleontology
• the study of fossils, which are
the remains of extinct organisms

28. Study of the interaction between
organisms and their environment

30. SOCIO BIOLOGY
• The study of social behaviour of the
animals that make societies.

31. Parasitology
• – the study of the parasites.

33. • The practical application of living organisms to
manufacture substances for the welfare of
mankind.

34. • The study of the immune system of the
animals which defend the body against
invading microbes.

35. • Study of insects.

37. PHARMACOLOGY
Study of drugs and their
effects on the system of
human body.

38. Biology include information about living
things but these information relate to the
other branches of sciences as well.
Each branch of science has relationship
with all other branches.

39. BIOPHYSICS
Principles of physics
biological phenomenon.

41. BIOCHEMISTRY
• It deals with the
study of the
chemistry of
different
compounds and
processes
occuring in living
organisms.

42. Biomathematics
• It deals with the study of biological
processes using mathematical
techniques and tools.

43. BIOGEOGRAPHY
• It deals with the study of the occurrence and
distribution of different living organisms in
different geographical regions of the world.

45. BIOECONOMICS
• It deals with the study of organisms
from economical point of view.
