Cellular and molecular biology encompass a wide range of biological concepts, such as the various organelles that make up individual cells, as well as diffusion and osmosis of substances at the cellular level. This area of biology also includes the processes of cellular division, photosynthesis and cellular respiration. Genetics is a biology topic concerned with the ways in which organisms inherit and transmit the biological information that drives life processes.

Microorganisms are organisms the naked eye cannot observe without the aid of a microscope, such as viruses, fungi and bacteria. Although they are invisible to the naked eye, microorganisms are a huge area of study in biology because there are more microorganisms on Earth than any other group of organisms. The name for a biologist who specializes in the study of microorganisms is a microbiologist.

In biology, an organ system is a group of bodily organs that function together. Examples include the digestive system, circulatory system and nervous system. In addition to studying individual systems, biologists also study the ways in which the systems interact with one another. For example, the circulatory system could not function without the aid of the respiratory system to oxygenate blood.
