Answer:
Some cells can support life independently, while other cells support life collectively
Explanation:
The cell theory, now universally accepted, contains three main statements: 1-all life forms are composed of cells, 2-cells always come from pre-existing cells, and 3-cells are considered as the basic units of all organisms. Cells are highly specialized structures that can perform specific functions. One single cell may contain all required materials to sustain life in a single-celled organism (e.g., prokaryotic bacteria and protists), where each cell is able to perform all metabolic functions, i.e., growth, development, reproduction, etc. Moreover, cells can also be organized into tissues, organs and systems of organs in multicellular organisms (e.g., plants and animals), in order to perform specific tasks such as, for example, gas exchange in specialized organs called lungs of terrestrial animals.
