Meaning of Cell Biology

What is Cell Biology:

Cell biology is the science that studies properties, characteristics, evolution, life cycle and the interaction of the cell with its environment. Cell biology is also known as cell biochemistry.

Studies of cell biology derive from previous disciplines such as cytology (branch of biology that studies cells) and histology (discipline that studies organic tissues).

Studies in relation to cell biology are relatively recent and focus on the idea that the cell is the fundamental unit of life, therefore it is important to know in depth what the cellular processes are and how they are carried out.

In this sense, cell biology studies the functioning of cellular systems and how they are structuredhence it is a multidisciplinary study area in which, especially, both cell biology and molecular biology are related.

Cell biology also studies the organisms that live in cells such as proviruses, viruses, bacteria, etc., which also contain DNA from current infections and from our ancestors, helping to find cures for diseases.

In theory, it is even believed that through the knowledge of a cell that contains the complete genome, a complete organism could originate.

function of cell biology

The subjects studied in cell biology are broad and there is no clear limit of study of the branches of biology. Some of the subjects that are part of cell biology are:

  • Cell visualization
  • cell membrane structure
  • Transport across cell membranes
  • cell signaling
  • cellular compartmentalization
  • Cycle and mechanics of cell division
  • cell death
  • Junctions and adhesions between cells and the extracellular matrix
  • Cellular Mechanisms of Development

Difference Between Cell Biology and Molecular Biology

Cell biology is a branch of specialization closely linked to molecular biology. The difference between molecular biology and cell biology lies in the focus of their study.

Molecular biology specifically studies the functions of molecular structure, especially in relation to genetic material (DNA and RNA).
