More commonly known as cell biology, cytology is the study of cells - the building blocks of life. Cells make up all living things, and it is only by understanding how they work that we can truly understand life processes. Cell biologists study the components that make up cells, as well as how cells grow, replicate, signal to each other, deal with invaders like viruses or other cellular organisms such as bacteria, and eventually die.
