Which statement about multicellular organisms is correct?
A. The cells of a multicellular organism must perform all life functions.
B. Every cell of a multicellular organism is responsible for movement.
C. A multicellular organism has many specialized cells.
D. Cells in multicellular organisms can reproduce by binary fission.
C. A multicellular organism has many specialized cells.
The correct statement about multicellular organisms is C. A multicellular organism has many specialized cells.
To determine the correct statement about multicellular organisms, let's analyze each option:
A. The cells of a multicellular organism must perform all life functions.
This statement is not entirely accurate. In multicellular organisms, different cells have specialized functions and work together to perform all life functions. Each cell type is responsible for specific tasks such as digestion, respiration, or reproduction. Therefore, not all life functions are performed by every cell.
B. Every cell of a multicellular organism is responsible for movement.
This statement is incorrect. While some cells in multicellular organisms are indeed responsible for movement, such as muscle cells, not every cell shares this responsibility. Other cells may be involved in functions such as nutrient absorption, information processing, or structural support.
C. A multicellular organism has many specialized cells.
This statement is correct. One of the defining characteristics of multicellular organisms is that they are made up of many specialized cells. These cells develop different structures and carry out specific functions to support the overall functioning and survival of the organism. Specialization allows multicellular organisms to have a higher level of complexity and efficiency in their organization.
D. Cells in multicellular organisms can reproduce by binary fission.
This statement is incorrect. Binary fission is a method of cell division that occurs in single-celled organisms, such as bacteria. In multicellular organisms, cell division occurs through the process of mitosis, which allows existing cells to divide and produce new cells for growth, repair, and maintenance.
Therefore, the correct statement about multicellular organisms is:
C. A multicellular organism has many specialized cells.
