They can be either unicellular‚ being able to function and show all seven characteristics of life with just one cell‚ or multicellular‚ composed of multiple cells that interact with each other. They can also be either prokaryotic‚ without membrane-bound organelles‚ or eukaryotic‚ with membrane-bound organelles. Cells also have many parts that help them to carry out their processes. The cell wall provides structure and defense‚ while the cell membrane controls what comes in and out of the cell. Ribosomes
