The following table shows the surface area-to-volume ratio of four cube-shaped cell models.

Cells are small, and their surface area is large in relation to their volume. This is an important feature for the transport of nutrients and water in to and out of the cell. Which of the four model cells do you think will be best able to supply nutrients and water to its cell parts?

• Cell model A

• Cell model B

• Cell model C

• Cell model D
