Are vacuoles in plant cells larger or smaller than in animal cells?
Larger
***Plant cells need to store more food/water than animal cells do***
Why are vacuoles bigger in plant cells than they are in animal cells?
They hold more water
**DOUBLE POINTS**
Why do animal cells NOT have chloroplasts?
Because animals do NOT do photosynthesis and do NOT have the make their own food.
