Science (Latin: Scientia = Knowledge) is an organized body of knowledge supported by observation and experimentation, derived from the study of natural phenomena of entire material universe. It contributes not only towards knowing how things happen, but also in organizing the knowledge thus obtained and making it available to others. The primary objective of science has been to give mankind greater security, better health and happy life. To achieve this, science has helped us in many ways. Today our lives are more comfortable because of science.
There are three major branches of science, namely Physics, Chemistry and Biology.
(Greek: bios = life, logos= discourse or study) is the study of life or the study of all living things. It was adopted as a scientific term by Jean Lamarck (1744-1829) in the early part of the nineteenth century and soon it spreads into general use to denote the study of living organisms. It aims at explaining the activities of living organisms as well as various life phenomena in term of Physics and chemistry. It is concerned not merely with co-relation between parts of the living organisms as a whole and its environment. It enquirers into the origin of life and explains the gradual evolution of the infinite of modern plants and animals.
Branches of Biology
a. Morphology: Morphology is the study of external and internal form and structure of organisms. It is subdivided into two branches:
b. Cytology: Cytology deals with cells. Cells are the small units, of which plants and animals are made.
g. Pathology: It is the study of plants and animals diseases, their causes, symptoms and cure.
