This document outlines the main divisions and branches of biology. The three main divisions are zoology, which studies animals; botany, which studies plants; and microbiology, which studies microorganisms. Some of the key branches described include morphology, which studies the form and structures of organisms; anatomy, which studies internal structures; physiology, which studies the functions of organisms; genetics, which studies heredity and genes; and ecology, which studies interactions between organisms and their environment. The document also lists several related fields that apply scientific principles to biological phenomena, such as biophysics, biochemistry, and biomathematics.

1. DIVISIONS AND BRANCHES
OF BIOLOGY AND ITS FIELDS
By Farheen Zahra

2. DIVISIONS OF BIOLOGY
• There are three main divisions.
• ZOOLOGY
• This division of biology deals with the study of animals
• BOTANY
• This division of biology deals with the study of the
plants
• MICROBIOLOGY
• This division of biology deals with the study of
Microorganisms such as bacteria etc.

3. BRANCHES OF BIOLOGY
• MORPHOLOGY
• This branch deals
with the study of
form and
structures of living
organisms.
• ANATOMY
• The study of
internal structures

4. • HISTOLOGY
• The microscopic study of
tissues.
• CELL BIOLOGY
• The study of structures
and functions of cells and
cell organelles is called cell
biology. Also deals with
cell division.

5. • PHYSIOLOGY
• This branch deals with the
study of the functions of
different parts of living
organisms.
• GENETICS
• The study of genes and
their role in inheritance is
called genetics.
Inheritance means
transmission of characters
through next generation.

6. • EMBRYOLOGY
• It is the study of
development of embryo
to new individual.
• TAXONOMY
• It is the study of naming
and classification of
organisms into groups or
sub groups

7. • PALEONTOLOGY
• It is the study of fossils,
which are the remains
of extinct organisms.
• ENVIRONMENTAL
BIOLOGY
• It deals with the study
of the interactions
between the organisms
and their environment.

8. • SOCIO-BIOLOGY
• This branch deals with
the study of social
behavior of the animals
that make societies.
• PARASITOLOGY
• This branch deals with
the study parasites.

9. • BIOTECHNOLOGY
• It deals with the practical
application of living
organisms to make
substances for the welfare
of mankind.
• IMMUNOLOGY
• It is the study of immune
system of animals, which
defends the body against
invading microbes.

10. • ENTOMOLOGY
• Study of insects
• PHARMACOLOGY
• It is the study of drugs
and their effects on the
system of human body.

11. Other Fields Related To Biology
• Biophysics
• It deals with the study of principle of
physics, which are applicable to
biological phenomena. For example
there is a similarity between limbs of
animals in biologyand working
principleslf lever inphysics
• Biochemistry
• It deals with the study of chemistry of
different compounds and processes
occurring in in living organisms. For
example the study of basic metabolism
of photosynthesis involves the
knowledge of chemistry.

12. • Bio mathematics
• It deals with thestudy of biological processes using
mathematical technique and tools.For example to
analyze data gathered aftdr experimental
work,biologists have to apply the rules of mathematics.
• Bio geography
• It deals withthe study of occurrence and distribution of
different species lf living organisms in different
geographcal regions of the world.
• Bio economics
• It deals with the study of organisms from economical
point of view.For example the.Cost value and the profit
value of the yield of wheat can be calculated through
bio economics and beenfitd or losses can be
determined.
