• Divide into smaller pieces

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

• Surface area

• Perimeter

• Volume

• Weight

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

This image shows how materials move into various sized cells in a given amount of time.... why does one square cell have more pink coloring than the others? 

• The surface area was too larger to get through
• The volume of the other cells was too large for the dye to get through
• There was not enough surface area for the dye to get through
• The volume was too low for the dye to stay in the square

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
