Definition of science, Physics, chemistry, organic and inorganic chemistry, Biology, botany and zoology

Definition of science and its main branches:-

Here you will get the definitions of many important subjects.If you are a good student or you want to become a good student. You have to start with definitions and try to understand hidden meanings given in definition. Trust me understanding of definitions provide you the basic concepts and most important you enjoy your subject. Let go through some definitions:

1) Science

    The systematic study of the nature and behaviour of the material and physical universe,  based on observation, experiment and measurement,and the formulation of laws to describe these facts in general terms. 

2)Physics:

    Physics is the natural science that studies matter, its motion and behaviour through space and time,  and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behave.

3)Chemistry:

   Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions their composition, structure, properties, behaviour and the changes they undergo during a reaction with other substances. 

4 )Organic Chemistry : 

    This is branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain Carbon in covalent bonding. Study of structure determines their chemical composition and formula. Study of properties includes physical and chemical properties, and their behaviour. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and the study of individual organic molecules in the laboratory and via theoretical study. 

5) Inorganic chemistry :-

    The branch of chemistry that deals with the study of compunds, which does not consist of carbon-hydrogen bond in it, is call Inorganic chemistry (very simple Definition) and Inorganic compunds comprise most of the earth's crust,  although the compositions of the deep mantle remain active areas of investigation. 

6)Biology: 

   Biology is the natural science that studies life and living organism, including their physical structure, chemical process, molecular interactions, physiological mechanisms, development and evolution. 

7) Botany:-

    Botany, also called plant science, plant biology or phytology, is the science of plants life and a branch of biology. Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively. 

8) Zoology:-

   Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habbits and distribution of all animals both living and extinct and how they interact with their ecosystem. 

  Note:-These subjects are chosen by me. Here my aim is not gave you a list of definitions which made you bored. But giving you a sight of seeing your subject from very basic level. These definitions provide you the things that you have to study in your subjects. So,  whatever your subject always take a look on definition and after that carry on your subject.

 

No doubt their are some words used in the definition which wants more exploration. So,  try yourself to find the meaning of that words written in your subject's definition.
