3. What term would you use to describe a cell whose shape is thin, flat, and scaly, such as
those found on the surface layer (epidermis) of the skin?
A. Columnar
B. Cuboidal
C. Squamous
D. Fusiform

4. How does the relationship between surface area and volume impact how large a cell can
be?
A. Volume is proportional to the cube of the diameter of the cell, so if diameter increases,
volume will increase much faster than surface area, limiting exchange of wastes and nutrients.
B. Volume and surface area both increase the same amount if the diameter of the cell
increases.
C. Surface area increases proportionately more than volume as the diameter of the cell
increases and, therefore, exchange of wastes and nutrients is more efficient in a large cell.
D. If the diameter of the cell doubles, the volume of the cell will increase by a factor of four.
E. If the diameter of the cell doubles, the volume of the cell will also double.
