Draw conclusions what happens to the surface area of a cell as its volume increases? one reason cells are small is that they need a large surface area as compared to volume so nutrients can dif- fuse in and wastes can diffuse out. solve the problem look at the cubes shown below. note the size and magnitude of difference in surface area and volume.

you need use the c-e-r for each question the c-e-r mind claim, evidence and reasoning.
thinking critically 1. estimate how many small cubes (1 mm) do you think it would take to fill the largest cube (4 mm)? c g 2. use models using the cubes as models, describe how a cell is affected by its size 3. infer explain how small change in cell size can have a huge impact on cellular processes.
