What is biology?

Biology is the branch of science that studies life and living organisms. This includes such subjects as the cell, genes, inheritance, microorganisms, plants, animals, and the human body.

There are many branches of science that are part of biology including ecology (how organisms interact with their environment), agriculture (the study of producing crops from the land), biochemistry (the chemical reactions needed to support life), botany (the study of plants), physiology (how living organisms function), and zoology (the study of animals).

Fundamentals of Biology

Biology is based on some key theories and fundamentals:

The cell - The cell is the fundamental unit of all life. Every living organism is made up of one or more cells.
Genetics - Genetics is the study of how organisms pass on features and traits from generation to generation.
Homeostasis - Homeostasis is the process by which an organism or cell is able to regulate its conditions. For example, humans are able to regulate their body temperature to 98.6 degrees.
Energy - All living organisms are able to use external substances for energy. For example, humans use food such as vegetables and meat. Plants gather energy from the Sun through photosynthesis.

The word biology comes from the Greek words "bios" which means life and "logia" which means "study of". Put those two words together and you get the "study of life."
