Determine which cell size will be the most efficient at obtaining the most amount of nutrients or eliminating wastes What factors will affect the movement of molecules?

Calculate the area and volume for each cube. Remember, always Include the unit of measure. For area, its is cm 2 and volume is cm 3. How do you calculate surface area of a cube? SA = L*W*6

Powdered agar + distilled water + phenolphtalein

Why did the investigation use phenolthalien?

Calculate the nondiffused area by using The formula, A=L*W
