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 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.
Animal, any of a group of multicellular eukaryotic organisms thought to have evolved independently from the unicellular eukaryotes. Animals differ from other multicellular eukaryotes, the plants and the fungi, in morphology and physiology in that animals evolved muscles, which allow them to be mobile.
