Cell Biology

Cell biology is the branch of biology that studies the cell, the basic unit of life. It analyzes the structure and function of various organelles, such as the nucleus, mitochondria, and endoplasmic reticulum. This field also explores essential cellular processes: cell division (mitosis and meiosis), metabolism, and intercellular communication. Cell membranes, composed of lipids and proteins, regulate exchanges with the environment. The cytoskeleton maintains cell shape and enables intracellular transport. Cell biology relies on advanced techniques such as microscopy and cell culture. It is fundamental for understanding development, differentiation, and diseases. Finally, it serves as a foundation for biomedical research and biotechnology.
