Key Questions:

1. Compare an animal and plant cells.
   • Plant and animal Cells both have: Cell membrane; cytoplasm; nucleus; mitochondria & ribosomes. Only plant Cells have: Cell wall; permanent vacuole and sometimes chloroplasts.
2. How are you able to tell the difference between an animal and plant cell?
3. Give 3 examples of specialised plant or animal cells. How are they different to other cells and how does this help the cells complete their specialist function?
   • That Cells have special characteristics, different organelles and shape, in order to fulfill their function.
4. What is the function of a root hair cell and how is the cell specialised to do this?
   • Root hair Cells have a large surface area to absorb water and nutrients. RHC have no chloroplasts as light does not get to them.
5. What adaptations do red blood cells have in order to efficiently carry oxygen around the body?
   • Red blood Cells have a rounded shape to allow it to flow smoothly. Is red due to the iron compound used to carry oxygen. RBC have no nucleus and a biconcave cross section to increase oxygen capacity.
6. What special adaptation do Elodea have? Why do they have this?
   • Elodea Cell have lots of chloroplasts to capture light.
7. Why do ciliated cells have hairs?
