The correct statement about multicellular organisms is: A multicellular organism has many specialized cells.
The correct statement about multicellular organisms is: A multicellular organism has many specialized cells.
To arrive at this answer, we can analyze each of the statements:
1. Every cell of a multicellular organism is responsible for movement.
This statement is incorrect. While some cells in multicellular organisms are responsible for movement (e.g., muscle cells), not every cell has this function. Many cells in multicellular organisms have other specialized functions, such as digestion, respiration, or reproduction.
2. A multicellular organism has many specialized cells.
This statement is correct. Multicellular organisms are made up of different types of specialized cells, each with specific functions. These cells work together to perform various tasks required for the organism's survival and functioning. Examples of specialized cells include neurons, red blood cells, and epithelial cells.
3. Cells in multicellular organisms can reproduce by binary fission.
This statement is incorrect. Binary fission is a form of asexual reproduction that occurs in certain unicellular organisms, such as bacteria and protists. In multicellular organisms, reproduction typically occurs through more complex processes, such as sexual reproduction involving the fusion of gametes.
4. The cells of a multicellular organism must perform all life functions.
This statement is incorrect. In multicellular organisms, different cells specialize in performing specific life functions. For example, nerve cells transmit signals, muscle cells contract, and gland cells produce hormones. No single cell performs all life functions; instead, these functions are distributed among the specialized cells of the organism.
