Cell biology is a branch of biology focused on the study of cell structure and function, on how cells form and divide, and how they differentiate and specialize. Cell biology defines both the general properties, common to most cell types, and also dissects the unique features of specialized cells, which allow them to perform different functions.

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function and behavior of cells. All living organisms are made of cells. A cell is the basic unit of life that is responsible for living and functioning of organisms. Cell biology is the study of structural and functional units of cells . Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle,

Cell biology is a branch of biology, which is mainly involved with the study of the cell, its types, structure, functions and its interaction with other cells. Cell biology is also called cytology and is derived from the Greek word “kytos”, meaning vessel. Important Topics in Cell Biology Why is Cell called the Fundamental Unit of Life?

Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized function, becoming a building block of a multicellular organism.

The cell is the basic structural and functional unit of life. Every cell consists of a cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Most plant and animal cells are only visible under a light microscope, with dimensions between 1 and 100 micrometres. Electron microscopy gives a much higher resolution showing …

An Overview of the Cell Cycle. The sudden separation of sister chromatids marks the beginning of anaphase, during which the chromosomes move to opposite poles of the spindle, where they decondense and reform intact nuclei. The cell is then pinched in two by cytoplasmic division, or cytokinesis, and cell division is complete ( Figure 17-2 ).
