SHORT ANSWER

26. The cells of unicellular organisms can survive on their own, but the cells of multicellular organisms must remain a part of the organism's body to survive.

27. Cells with circular DNA are prokaryotic.

28. cell wall, chloroplast, large vacuole, chlorophyll

29. Sample answer: All organisms are composed of one or more cells; the cell is the basic unit of life in all living things; all cells come from existing cells.

30. Support: Plants do not have a skeleton that allows them to stand upright. Cell walls help to support the plant. Protection: When a plant cell loses or gains too much water, the cell wall helps protect the cell membrane from bursting or tearing.
