Ap Biology Cell Surface Area to Volume Ratio

Which cells are more efficient at obtaining nutrients?

• Small Cells
• Medium Size Cells
• Large Cells
• X-Large Cells

The absorption of nutrients is determined by...

• The cell's volume
• The cell's surface area
• The cell's ribosomes
• The cell's DNA

The amount of nutrients needed is determined by...

• The cell's volume
• The cell's surface area
• The cell's Rough ER
• The cell's Smooth ER

Which type of cell is easier to get Oxygen in and waste out?

• small cell
• large cell

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

As a cell’s size increases, its ratio of surface area to volume decreases.

• True
• False

How can surface area (SA) be increased? 

• Grow larger
• Divide into smaller pieces

Define Surface area

• The total area on the surface of an object
• Length X Width 
• 6 X (length X width)
• Add up the sides and divide by 4

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

• Surface area
• Perimeter 
• Volume
• Weight
