The correct statement about multicellular organisms is: D) a multicellular organism has many specialized cells.
In multicellular organisms, cells often differentiate into specialized types to perform specific functions, contributing to the overall functioning of the organism.
To clarify the other options:
- A) Everyday sale of a multicellular organism is responsible for movement: This statement is unclear and seems to contain a typographical error ("sale" instead of "cell").
- B) Cells in multicellular organisms can reproduce by binary fission: This is incorrect, as binary fission is a form of asexual reproduction typically found in unicellular organisms like bacteria.
- C) The cells of a multicellular organism must perform all life functions: This is incorrect as different cells often specialize in particular functions, rather than each cell performing all functions on its own.
