Cell (biology) - Wikipedia
Cells emerged on Earth about four billion years ago. All organisms are grouped into prokaryotes, and eukaryotes. Prokaryotes are single-celled and include archaea and bacteria. Eukaryotes can be single-celled or multicellular, and include protists, plants, animals, fungi, and some species of algae.

Cells Cells in Context In multicellular organisms, cells work together in teams. Multiple cell types, each specialized for a certain function, team up to form tissues. And multiple tissue types are organized into organs.

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) - New World Encyclopedia
There are two basic types of cells, eukaryotic and prokaryotic. Prokaryotic cells are usually single, while eukaryotic cells are usually found in multicellular organisms. Prokaryotes are distinguished from eukaryotes on the basis of nuclear organization, specifically their lack of a nuclear membrane.
