Cell Surface Area to Volume Ratio Problem: Which cell has the greatest surface area to volume ratio? Hypothesis: ______________________________________________________________________________ Variable Identification: Independent: ____________________________________________________________ Dependent: _____________________________________________________________ Constants: ______________________________________________________________ ________________________________________________________________________ Materials Scalpel Agar Ruler 250 ml beaker 100 ml sodium hydroxide solution Timer Plastic spoon Paper towel Procedure: 1. Obtain a piece of agar that is 4 cm by 3 cm. Make three model cells by using the knife to cut three cubes from the phenolphthalein agar. Cell A should be 3 cm on each side, cell B should be 2 cm on each side, and cell C should be 1 cm on each side. Use the ruler to make exact measurements. 2. Calculate the area of one side of each cell. Calculate the total surface area of each cell. Record your data in Table 1. 3. Calculate the volume of each cell. Record your data in the table. 4. Calculate the ratio of surface area to volume for each cell. Record your data. 5. Put the model cells in the beaker. Carefully cover them with 100 ml sodium hydroxide solution, which turns the agar pink.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
