BIOLOGY

SCIENCEScience is the study in which• OBSERVATIONS ARE MADE, • EXPERIMENTS ARE DONE • AND LOGICAL CONSEQUNCE ARE DRAWN• IN ORDER TO UNDERSTAND THE RINCIPLES

OF NATURE.

What is Biology?• Bio – means life• logos – to study / the study

• BIOLOGY – is the study of life / the study of living things

Some Branches of Biology

The study of form and structure of living organisms.

BIOLOGY TEAMS - SMAMDA

Morphology

Anatomy is the study of the internal structures (kidney, hert, liver etc.)

BIOLOGY TEAMS - SMAMDA

The microscopic study of tissues is called histology.

HISTOLOGY

and

Cell biology

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

Physiology

• Genetics –• the study of

genes and their role in inheritance.

• Inheritance:• The transmission

of character from one generation to the other.

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

BIOLOGY TEAMS - SMAMDA

Relationship of biology to other sciences

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.

BIOPHYSICSIt deals with the study of

Principles of physics which are applicable to

biological phenomenon.

BIOCHEMISTRY• It deals with the

study of the chemistry of different compounds and processes occuring in living organisms.

Biomathematics

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

BIOGEOGRAPHY• It deals with the study of the occurrence and

distribution of different living organisms in different geographical regions of the world.

BIOECONOMICS • It deals with the study of organisms

from economical point of view.
