All cells can be sorted into one of two groups Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells.
In biology, a cell is the fundamental structural and functional unit of all living organisms Cells can vary enormously in appearance and function. 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. Learn how cell function depends on a diverse group of nucleic acids, proteins, lipids, and sugars.
