Biology -The Science of Life and Living Organisms

Biology is a natural science and is concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.

Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be fundamental parts of modern biology:

1. Cells are the basic unit of life

2. New species and inherited traits are the product of evolution

3. Genes are the basic unit of heredity

4. An organism regulates its internal environment to maintain a stable and constant condition

5. Living organisms consume and transform energy.

Sub-disciplines of biology include:

Biochemistry which examines the rudimentary chemistry of life.

Molecular biology which studies the complex interactions of systems of biological molecules.

Cellular biology examines the basic building block of all life the cell.

Physiology examines the physical and chemical functions of the tissues, organs, and organ systems which make up an organism.

Ecology the study which examines how various organisms interact and associate with their environment.

If you have a natural curiosity and a wish to understand it then biology is a fascinating area of study.

The range of careers it can open are endless including Medicine, Biotechnology, Genetic Engineering, Agriculture, Horticulture, Forestry, Land Management and Healthcare.
