Question

Write three functionsof Cilia and flagella

Answer 1

Answer:

• Cilia and flagella move liquid past the surface of the cell.
• For single cells, such as sperm, this enables them to swim.
• For cells anchored in a tissue, like the epithelial cells lining our air passages, this moves liquid over the surface of the cell
• (e.g., driving particle-laden mucus toward the throat).

Answer 2

Answer:

Cilia

Motile' (or moving) cilia are found in the lungs, respiratory tract and middle ear. These cilia have a rhythmic waving or beating motion. They work, for instance, to keep the airways clear of mucus and dirt, allowing us to breathe easily and without irritation. They also help propel sperm.

Flagella

Flagella Function

They help an organism in movement. They act as sensory organs to detect temperature and pH changes. Few eukaryotes use flagellum to increase reproduction rates. Recent researches have proved that flagella are also used as a secretory organelle.
