Assignment: Cell Size Exploration
Cell
Length of one side
Area of one side of the cube
(l × w)
Surface area (area of one side × 6 sides)
Volume
(l × w × h)
Surface area/volume
The ratio of surface area to volume
(for example, 5:1)
A
1 cm
B
2 cm
C
3 cm
Refer to your data table to answer these questions.
What happens to the ratio of surface area to volume as the cell size increases without the cell changing shape?
What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
