Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things Most cells have one or more nuclei and other organelles that carry out a variety of tasks Some single cells are complete organisms, such as a bacterium or yeast
- Cell - National Human Genome Research Institute
All cells can be sorted into one of two groups: eukaryotes and prokaryotes A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells
- Cell Biology - National Geographic Society
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
