- Centrioles, flagella, cilia
- Centrioles
- Only in animal cells
- make and organise microtubules
- made of a protein called tubulin
- During cell division- microtubules form the spindle
- Flagella
- long, thin extensions from the cell
- Cilia
- Cilia are shorter structures found in large numbers
- Cilia
- Flagella are longer and usually found in ones or twos
- Usually cause the cell to swim through a liquid
- long, thin extensions from the cell
- Cilia
- Cilia are shorter structures found in large numbers
- Centrioles
- Produce movement
- Found in some animal cells but rarely in plant cells
- Contain microtubules arranged in a 9+2 arrangement
- ie) 2 microtubules in centre
- + a ring made of nine microtubule pairs
- movement is formed by these microtubules moving against each other
- + a ring made of nine microtubule pairs
- ie) 2 microtubules in centre
- The movement of the cilia can move fluids over the surface of the cell
- eg) lining of the bronchus, cilia in throat
