Cell publishes findings of unusual significance in any area of experimental biology, including but not limited to cell biology, molecular biology, neuroscience, immunology, virology and microbiology, cancer, human genetics, systems biology, signaling, and disease mechanisms and therapeutics.
Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all organisms, and that all cells come from pre-existing cells. Organisms are broadly grouped into eukaryotes and prokaryotes.
Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. These components vary depending on whether the cell is prokaryotic or eukaryotic, and whether it belongs to a plant, animal, fungus, or protist.
All cells evolved from a common ancestor and use the same kinds of carbon-based molecules. Learn how cell function depends on a diverse group of nucleic acids, proteins, lipids, and sugars.
Definition of Cell A cell is the basic structural and functional unit of all living organisms, responsible for various life processes and containing essential biological molecules.
A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.
From plant stems to bacterial shells, cell walls are far more than rigid barriers—they’re living, adapting structures. Scientists are uncovering how they maintain shape, remodel themselves, and even ...
