Cell biology is the study of cells, including their structure, function, communication, signaling, and cell cycle and division.
It involves examining both single-celled and multicellular organisms and has applications in fields such as genetics, molecular biology, cytochemistry, and biochemistry.
Over the years, advancements in technology have made it possible to study cells in greater detail, using techniques such as imaging to observe smaller cellular organelles.
Cell biology is important for understanding the body as a whole, as well as answering complex questions about the relationship between cellular networks, the evolutionary relationship between genomes, and the complexity of biomolecules in different living organisms.
It is also a good place to do research on single cells because they are easy to change and watch.
