Science
in the World
The science is broad filed in world which can be
classified into different types and categories .There is different types,
Ø Biology
Ø Chemistry
Ø Physics
Ø Methodology
Only I here
to classified the biology.
Biology
The filed or type of science in which study the
living organisms. The words biology is derived from Latin words 'Bio “means living organisms, living
individual and "Logos"
means study or research something.
Biology is also a broad filed of science in which we study and experiment the unicellular microorganisms, simple multicellular and complex multicellular organisms. One biologist can also solved the scientific problem that he faced in biological problem.
Biologist solved the problem with
help of scientific method. He used the method to analyze the data and Observed
it after that he started the experiment on them. When those experiment cannot
be rejected by any others scientist than they become a scientific Law.
Classification
of Biology
Biology is classified into three different major
types.
Ø Zoology
Ø Botany
Ø Microbiology
Zoology
The study of animals called zoology .In the world 1.5 types of animal are discovered which are known by zoologist. In which the one zoologist studies the behavior and habits of animals and how they interact with their environment .Animal are heterotroph.
They depend on plant for food and nutrition. Animals are always a consumer .For
their nutrition they competitive with one another and strong who compete other
different species of animals are survive in their environment. In this field we
also know how animal produced a fertile offspring.
Botany
The study of plants is called botany .Botany is the
broad filed of science in which one biologist study the growth and development
of plants. In the World 0.5 million types
of plants are known by biologist.
Role of Plants in Environment
- Plants
play an important role in the environment all the ecosystem depends on plants
for food.
- Plants
are producers and produced a food by the process of photosynthesis in presence
of sun light.
- They autotrophs do not depend on any other organisms for food.
- Plants also provide a habitat for all species and provide them a food for survival.
In the botany field we also observe how plant is behaved in stress and drought for this we completely study the micro branched of botany which knows as a physiology.

In physiology we study the normal function
of plants and their parts with environment. How plant interact with their
environment and how get nutrients from soil for this purpose we also study
ecology. Ecology is the study of
organisms or plants which relate to their environment.
Microbiology
The study of microorganisms is called microbiology.
Like as viruses and bacteria.
Virology
The study of
viruses is called virology. Viruses are a
cellular present between the borderline of living and nonliving organisms
.viruses are use the metabolic machinery of living organisms for multiplication
and give a harmful effects to living organisms. It also causes a diseased in
living cell.
Bacteriology
The study of bacteria is called bacteriology.
Significance
of bacteria
The bacteria
have great role in the world.
- Bacteria
play an important role in the Environment they act like a decomposer.
- Bacteria
are also used in Genetic Engineering for the production of desirable gene.
- Bacteria
are also used for the production of Drugs in medical field.
- Bacteria also play an important role in recycling process they decomposed the dead organic matter.
- Bacteria also control the environmental pollution.
Bacteria play an important role in growth and
development of plant .They convert the atmospheric nitrogen into ammonia .The
ammonia are used for the normal growth of plant .This process is called
ammonification and the whole process circulated in nitrogen cycle.
