Notes from NEET topper
Structure of Cilia and Flagella:
- Cilia and flagella are slender, hair-like organelles found on the surface of many eukaryotic cells.
- They are composed of microtubules arranged in a 9+2 pattern (nine doublet microtubules surrounding two central singlet microtubules).
- Cilia are shorter and usually occur in large numbers on a cell’s surface, while flagella are longer and typically exist singly or in pairs.
- The core structure of cilia and flagella is called the axoneme, and it is responsible for their movement.
