CBSE Biology 3.99

The word “biology” is derived from the greek words /bios/ meaning /life/ and /logos/ meaning /study/ and is defined as the science of life and living organisms. An organism is a living entity consisting of one cell e.g. bacteria, or several cells e.g. animals, plants and fungi.Aspects of biological science range from the study of molecular mechanisms in cells, to the classification and behaviour of organisms, how species evolve and interaction between ecosystems.

Biology is the study of living things and their vital processes. Because biology covers such a broad area, it has been traditional to separate the study of plants (Botany) from that of animals (Zoology), and the study of structure of organisms (Morphology) from that of function (Physiology).

Despite their apparent differences, all the subdivisions are interrelated by basic principles, so current practice tends to investigate those biological phenomena that all living things have in common. The advancement of knowledge and technology has resulted in further categorizations that include:
Cell biology,
Ethology,
Population biology,
Ecology,
Genetics,
Biochemistry, Molecular biology,
Microbiology,
and Physical anthropology.
Biology often overlaps with other sciences; for example, Biochemistry and Toxicology with Biology, Chemistry, and medicine; Biophysics with Biology and Physics; Stratigraphy with Biology and Geography; Astrobiology with Biology and Astronomy. Social sciences such as Geography, Philosophy, Psychology and Sociology can also interact with Biology, for example, in administration of biological resources, Developmental biology, Biogeography, Evolutionary Psychology and Ethics.
Generally Biology is considered as an easy subject when compared with Physics and Chemistry.But students should must remember that in medical entrance exam(NEET) 50% weightage is covered by Biology. This subject needs proper guidance, study material and systematic study.
