Cell biology is a branch of biology that looks at the cell, the basic unit of life. It talks about all parts of the cell, such as its structure, how it grows and divides (mitosis and meiosis), and the things that cells do, such as breathing and dying. Cell biology is not a separate field of study. Instead, it is closely related to genetics, molecular biology, and biochemistry.

The study of cells relies on one of biology’s founding principles—the cell theory—which would not have been conceivable before the microscope was invented. Cell researchers now have access to high-resolution images of even the tiniest cellular structures and organelles thanks to cutting-edge microscopes like the Scanning Electron Microscope and the Transmission Electron Microscope.

What Are Cells?

Cells make up the building blocks of every living thing. The number of cells that make up some organisms can reach the trillions. Eukaryotic cells and prokaryotic cells are the two main categories of cells. In contrast to prokaryotic cells, which lack a membrane enclosing their nucleus, eukaryotic cells do. In spite of the fact that all living things are made up of cells, the cells themselves vary greatly. Cell size, shape, and the number and kind of organelles they contain are only a few examples of these varying features. Comparing animal cells with bacterial cells with plant cells, for instance, reveals parallels and differences. There are a variety of ways in which cells can multiply. Binary fission, mitosis, and meiosis are only a few examples of these processes. The DNA contained within a cell serves as a blueprint for how the cell is to function.

Careers in Cell Biology

Numerous professions are accessible after completing studies in cell biology. In the scientific community, many cell biologists hold research positions in universities and private companies. Optional alternatives:

  • Cell Culture Specialist
  • Clinical Quality Auditor
  • Clinical Researcher
  • Food & Drug Inspector
  • Industrial Hygienist
  • Medical Doctor
  • Medical Illustrator
  • Medical Writer
  • Pathologist
  • Pharmacologist
  • Physiologist
  • Professor
  • Quality Control Specialist
  • Technical Writer
  • Veterinarian

Why Do Cells Move?

Numerous cellular processes rely on cellular mobility. Cell division, determining cell shape, fending off pathogenic invaders, and repairing damaged tissues are all examples of these processes. Transporting materials into and out of a cell and relocating organelles during cell division both require intracellular mobility.
