what is biology about

Hello friends welcome, in this article you have been given information about biology like, what is biology, field of biology and what is biology, definition of biology, what is biology, and types of animals and The classification is explained in simple and easy,

This subject is studied from class 6th to 12th and also in higher cla

What is Biology :

The term biology was first used in 1801 by Lamarck, a French zoologist, and Trevineras, a German zoologist. Biology is a Greek word derived from two words meaning life, life or organism and which means “study”. Thus the meaning of biology is the study of organisms.

Biology is a branch of natural science, which studies the organisms in which there is life, that is, all the activities related to life take place in those organisms,

For example, their origin, development and reproduction. Consequently, organisms that are born and die from their mother organism can be considered as descendants of that mother organism.

Biology is the branch of science that studies them.

A scientist named Aristotle created biology as a new field and provided a complete explanation of the field, making him the “father of biology”.

Fields of Biology :

For the convenience of study, biology is divided into two areas.
Biology is the branch of biology under which the nutrition, origin, development of all organisms, the effects of environment on them, activities related to life, reproduction, death etc. are studied in detail.
It is called zoology, the father of zoology is Aristotle, who has written his book about zoology,

Historia Animalia in which 500 animals are described.
Botany is the study of all types of plants, shrubs and other plants.
Theophrastus, known as the “father of botany”, was a salt scientist who wrote Historia Plantarum, a book in which he listed 500 different varieties of plants.

Definition of Biology :

An organism is a living entity consisting of a single cell, for example bacteria, or several cells of animals, plants and fungi, for example.

The resultant things which are produced by a special artificial species process are called ‘Jiva’. They have a limited life cycle. We are all creatures. Some basic processes go on in living things.

  • (1) Nutrition: Under this, all living beings get energy for themselves from the receipt of special substances.
    (2) Respiration: Through this process the animal expels vital gases.
    (3) Sensitivity: Organisms are sensitive to environmental stimuli.
    (4) Reproduction: It is a unique and very important process found in living organisms. in which the reproductive organism allows the production of offspring of its own kind and provides confirmation of biological existence.

Branches of Biology :

Biology can be mainly divided into two parts.

  1. Zoology
  2. Botany

Biology was divided into zoology and botany, but the field of biology is very vast, so these two disciplines proceed and split into more branches.

Zoology :There is a science related to animals, in which all types of animals are studied, in the animal kingdom those organisms come which do not have a cell wall. Those capable of circulation but cannot manufacture food on their own.

Botany:It is the science related to plants, it studies all types of plants, the plant world includes organisms that have a cell wall made of cellulose, as well as the action of chlorophyll and photosynthesis.

Important Years in The History of Biology :

1665 Robert Hooke – Description of cells in cork tissue
1683 Antoine van Leeuwenhoek – Microscope detected bacteria, unicellular organisms, blood cells and spermatozoa.
1758 Carl von Linnaeus – In his book ‘Sistema Naturae’ he classified the animal world and the plant world, which is still valid today.
1839 Theodor Schwann and Mathias Jakob Schleiden – founders of cell theory.
1858 Charles Darwin (1842, unpublished) and Alfred Russell Wallace – independently established the theory of evolution.
1866 Gregor Mendel – Genetics is founded, the first publication on the experiments of hybridization in plants.
1925 The era of mathematical biology began with the Lotka-Voltra equation
Virus discovery by Wendell Meredith Stanley in 1935
1944 Oswald Avery showed that DNA is the carrier of genetic information, not protein.
In 1950, Barbara McClintock published the discovery of dynamic elements in genetic material, but this was long invalid.  Their discovery forms the basis of genetic engineering processes in the present day.
1952 Alan Lloyd Hodgkin and Andrew Fielding Huxley establish the fundamental equations of electrophysiology.
1953 James D. Watson and Francis Crick together published the double helix structure of DNA.  Rosalind Franklin and Maurice Wilkins were also instrumental in elucidating the structure.
1973 John Maynard Smith and George R.  Price introduced the concept of evolutionary stable politics, which is useful in many fields, including game theory and economics.
1982 Stanley Prusiner hypothesized prions, which are infectious agents without genetic material.
1983 Carey Mullis invented the polymerase chain reaction (PCR).  This can result in DNA molecules being multiplied millions of times in the laboratory.
1990-2003 Sequencing of the Human Genome by the Human Genome Project
