Question

13 multiple choice 3 points many protists and bacteria are unicellular. unicellular means they -- are made of many cells are made of only one cell are made of cellulose and have a nucleus can only live inside another living organism

Explanation:

The term "unicellular" is derived from Latin roots: "uni-" meaning one, and "cellular" referring to cells. By definition, it describes organisms composed of a single cell. The other options are incorrect: "made of many cells" describes multicellular organisms; "made of cellulose and have a nucleus" does not define unicellularity (many unicellular organisms lack cellulose or a nucleus); "can only live inside another living organism" describes obligate parasites, not all unicellular life.

Answer:

are made of only one cell
