What are the similarities between animal and plant cells?
Both contain nucleus, cell membrane, mitochondria and cytoplasm
What are the differences between animal and plant cells?
Plant cells have a refusal shape and animal cells have irregular shapes
What does the cytoplasm do?
Where chemical reactions happen
What does the cell membrane do?
Controls what goes in and out of the cell
What does the nucleus do?
Carries the genetic information and control what happens inside the cell
What does the mitochondria do?
Where respiration happens
What does the vacuole do?
Contains a liquid (cell sap) which keeps the cell firm
What does the cell wall do?
Made of tough substance called cellulose which supports the cell
