The main function of flagella and cilia is to aid in cell movement and to move substances around cells.
Detailed Explanation
Flagella and cilia are cellular appendages found in both prokaryotic and eukaryotic cells. They extend from the cell surface and play crucial roles beyond just locomotion.
Here's a breakdown of their functions:
- Cell Movement: This is the primary and most well-known function. By beating or rotating, flagella and cilia propel cells through fluids.
- Moving Substances: Cilia, in particular, are often involved in moving substances around the cell or directing the flow of substances along tracts. Think of the cilia in your respiratory tract that sweep mucus and debris out of your lungs.
Function Summarized
| Feature | Function |
|---|---|
| Flagella | Primarily cell movement (locomotion) |
| Cilia | Cell movement and moving substances around the cell or along tracts. |
As mentioned in the reference, "Both prokaryotic and eukaryotic cells contain structures known as cilia and flagella. These extensions from the cell surface aid in cell movement. They also help to move substances around cells and direct the flow of substances along tracts."
