The amount of space something takes up is called the....

• Surface area (SA)

• Density

• Volume (V)

• Mass

For cells to stay alive they require what type of SA:V ratio?

• Large SA, Large V

• Small SA, Large V

• Large SA, Small V

• Small SA, Small V

High Surface area to volume ratio allows cells to do what quickly?

• Move materials around inside the cell

• Move materials in and out of the cell

• Communicate to other cells

• Divide

Microvilli are tiny projections that extend off the cell to increase the Surface Area.  What purpose might that serve? 

• Increased absorption
• Better communication among cells
• Maintain homeostasis 
• Decreased oxygen use

The amount of nutrients needed is determined by...

• The cell's volume

• The cell's surface area

As a cell becomes larger, its

• surface area increases faster than its volume.
• volume increases faster than its surface area

The larger a cell is, the more difficult it is for the cell to move enough nutrients and wastes across its cell membrane to maintain its normal functions.

• True
• False
