1

If you looked at the cells of an elephant and a longhorn beetle with a light microscope, you would find that

the cells would be approximately the same size.

2

Which of the following statements regarding cell size is correct?

1. A higher surface-area-to-volume ratio is more efficient for cellular activity.

2. A lower surface-area-to-volume ratio is more efficient for cellular activity.

3. Bacteria have a lower surface-area-to-volume ratio than plant cells because they have a smaller surface area.

4. Larger cells are more efficient than smaller ones because they are able to perform more activities within the interior of the cell.

1. A higher surface-area-to-volume ratio is more efficient for cellular activity.

3

____________ is the evolutionary process by which cells have developed organelles, specialized structures that perform specific functions, in order to increase the efficiency of cell metabolism.

Compartmentalization

4

One recognizable difference between plant and animal cells is that

plant cells have thick, rigid cell walls. Animal cells do not have cell walls.

5

What is the function of the plasma membrane in plants and animals?

1. it allows the cells to divide

2. it compartmentalizes the cell

3. to regulate entry and exit of materials

4. it increases the surface area of the cell

3. to regulate entry and exit of materials

6

Compartmentalization is the process by which cells

have evolved organelles, membrane-enclosed structures that perform specific functions, to increase the efficiency of cell metabolism.

7

Both plant and animal cells are bound by _________ ___________ that enable the
regulation of materials passing into and out of the cell

plasma membranes

8

The surface-area-to-volume ratio is used to measure

1. cell structure

2. cell efficiency

3. cell membranes

4. animal and plant membranes

2. cell efficiency

9

organelles are,

the main units of cell
function.
