Cilia can be found in both animal and plant cells, but they are more prevalent in animal cells.
Cilia: A Cellular Component
Cilia are microscopic, hair-like structures that extend from the surface of certain cells. Their primary function involves movement, either of the cell itself or of substances across the cell's surface. Understanding their presence in different organisms is crucial.
Cilia in Animal Cells
- Widespread Occurrence: Cilia are found in most animal cells, playing vital roles in various physiological processes.
- Examples:
- The respiratory tract utilizes cilia to clear mucus and debris.
- Ciliated cells line the fallopian tubes, aiding in the movement of the egg.
Cilia in Plant Cells
- Limited Presence: Cilia are found only in some plant cells.
- Examples: Cilia can be found in motile sperm of certain plants like cycads and ginkgo.
