Which statement is correct about the movement of unicellular organisms and multicellular organisms? (1 point) A. Parts of a unicellular organism are specialized for movement. B. Every cell of a multicellular organism is responsible for movement. C. One cell in a multicellular organism is specialized for movement. D. The cell of a unicellular organism is responsible for movement.
C. One cell in a multicellular organism is specialized for movement.
The correct statement about the movement of unicellular organisms and multicellular organisms is:
C. One cell in a multicellular organism is specialized for movement.
To determine which statement is correct about the movement of unicellular organisms and multicellular organisms, we can break down each option and consider the characteristics of these organisms.
A. Parts of a unicellular organism are specialized for movement.
When it comes to unicellular organisms, such as bacteria or protozoa, they are made up of only one cell. This single cell is responsible for all the functions of the organism, including movement. Therefore, statement A is correct.
B. Every cell of a multicellular organism is responsible for movement.
In multicellular organisms, such as animals or plants, there are specialized cells within the organism that perform specific functions, including movement. However, not every cell is responsible for movement. Cells in multicellular organisms have specific roles and functions, such as muscle cells for movement, nerve cells for communication, or skin cells for protection. Thus, statement B is not correct.
C. One cell in a multicellular organism is specialized for movement.
In multicellular organisms, there are indeed specialized cells responsible for movement. For example, in animals, muscle cells allow for locomotion. In plants, specialized cells called trichomes can move to capture prey. Therefore, statement C is correct.
D. The cell of a unicellular organism is responsible for movement.
As mentioned earlier, unicellular organisms consist of a single cell, and that cell is responsible for all their activities, including movement. Therefore, statement D is correct.
In conclusion, both statements A and D are correct about the movement of unicellular organisms, while statement C is correct about the movement of multicellular organisms.
