Which term is used for the basic life unit that can carry out life processes on its own?

• A. Cell
• B. Molecule
• C. Atom
• D. Organism

Answer: (A)

The basic unit that can carry out life processes on its own is the cell. A cell has the necessary organization to perform metabolism, grow, respond to stimuli, and reproduce. It contains structures like the cell membrane to regulate transport, cytoplasm, and various organelles that carry out specific tasks such as energy production and protein synthesis. Molecules and atoms lack this level of organization and cannot carry out the full set of life processes independently. An organism refers to a living being, which can be unicellular or multicellular, and is made up of one or more cells rather than being the smallest unit that can function on its own. Therefore, the correct term is the cell.
