Divisions of Biology: Cell Biology

Cells are often described as the ‘basic unit of life‘. Cell biology is a sub-discipline of biological studies that deals with the study of cells in all aspects. From cell anatomy, cell death, cell respiration to the processes of cell divisions like mitosis and meiosis, cell biology covers all topics.

Originally derived from the Greek word ‘kytos’ meaning contain, this area of biology strictly deals with the physiological properties of cell, the organelles that present in these, cell structure, the pattern of interaction between cells and cell pathways. The study of cells focuses on both single-celled organisms like bacteria and protozoa to complex, multi-cellular organisms like plants, animals and human bodies. Tracking down the nature of these cells, their functions and similarities and dissimilarities of cells in living organisms are all a part of the course.

What makes cell biology a popular academic choice?

Think about it – what if you were never able to get an ailment traced? Today, you are aware of diseases and their symptoms. There are millions of health professionals at service trying you treat patients from the adversities and lethal impacts of malicious diseases like the Big C, Alzheimer’s disease, cystic fibrosis, meningitis or even malaria. These problems spring in at molecular levels. Therefore, by understanding how cells work and function, cell biologists are able to make new discoveries in the field of medicine.

After analyzing all forms of living organisms like plants, animals and human beings, cell scientists carefully discover a series of advanced drugs, vaccines and sedative to ensure proper cure to a serious ailment. Why just diseases, cell biology has contributed towards the human fertility program. Even forensic teams put cell biology into practice to execute successful solutions like DNA fingerprinting to solve murder or other complex criminal activities.

Cell biologists analyze plants and define their genetic behavior. These work wonders in encouraging the production of better and modified crops.
