The correct statement about multicellular organisms is: A multicellular organism has many specialized cells.
In multicellular organisms, cells often have specific functions (specialization) that contribute to the overall function and survival of the organism. The other statements are incorrect for the following reasons:
- Cells in multicellular organisms can reproduce by binary fission: This is typically true for unicellular organisms (like bacteria), not multicellular ones.
- The cells of a multicellular organism must perform all life functions: In multicellular organisms, different cells perform different functions, so not every cell needs to perform all life functions.
- Every cell of a multicellular organism is responsible for movement: This is incorrect as not all cells are responsible for movement; many cells have other specialized roles.
