What do biologists use in the field?

Biologists do a lot of work outside the laboratory. They study different areas to find out how the animals, plants and microorganisms interact with each other and with the environment. They find out how an area changes over time and how it is influenced by human activity.

Classification of biological molecules

Biological molecules can classified in to two major categories. These are organic molecules and inorganic molecules. Organic molecules are molecules that contain carbon and hydrogen. They are the main structural components of living cells and tissues. The four major classes of organic molecules are carbohydrates, lipids,proteins and nucleic acid. Inorganic molecules are biological molecules that contain either carbon or hydrogen or neither of them.They are relatively small and simple compounds such as water,simple acids,bases and salts.
