Some types of organisms, such as prokaryotes, are composed of only a single cell. In these unicellular organisms, the one cell is a functionally independent organism capable of carrying out all life activities. In more complex multicellular organisms, including plants and animals, major life activities are divided among varying numbers of specialized cells. Individual s cells of multicellular organisms are potentially capable of surviving by themselves if placed in a chemical medium that can sustain them: the cell is the smallest unit that has the properties of life. Although deoxyribonucleic acid (dna) and ribonucleic acid (rna)
