Cells and Cell Contents
- Organelles
- Have their own specific
role within the cell
- Each contribute to the
survival of the cell
- DIVISION OF LABOUR
- Cytoskeleton
- Cells contain a network
of fibres made of protein
- They provide an internal framework = cytoskeleton
- Actin filaments
- Fibres are able to move against each other
- Cause the movement in some
white blood cells
- Microtubules
- May be used to move a
microorganism through a liquid
- Undulipodia & Cilia
- Structurally they are the same
- Made up of a cylinder containing nine
microtubules arranged in a circle
- Another two microtubules in
a central bundle
- Undulipodia are longer than cilia
- Undulipodia and cilia can move
- The microtubules use energy produced by Adenosine triphosphate (ATP)
- Some Bacteria have flagella
- Have a different internal structure to Undulipodia
