Question
- Cilia and flagella are some of the cell modifications found in animals. Which of the following specific functions is correct about the difference between the two?*1 pointA. Cilia help increase surface area, while flagella are used for defense.B. Cilia arise from the cell surface, while flagella are locomotory organelles.C. Cilia are long whip-like structures, while flagella are short hair-like projections that arise from the body of the organismD. Cilia are short hair-like structures, while flagella are long whip-like structures that grow from the body of microorganisms.
Solution
The correct answer is D. Cilia are short hair-like structures, while flagella are long whip-like structures that grow from the body of microorganisms.
Here's why:
Cilia and flagella are both structures that protrude from the cell body and are involved in cell movement. However, they differ in their size and function.
Cilia are short, hair-like structures that cover the entire surface of certain cells. They move in a coordinated, wave-like manner to propel the cell or move substances over the cell's surface.
On the other hand, flagella are longer, whip-like structures. They are usually fewer in number (one or two per cell) and move in a whip-like manner to propel the
