What determines the rate of nutrients and waste are exchanged from the cell and the environment?

• surface ratio
• volume
• surface area
• 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

What does not grow with the cell?

• DNA
• Vacoules
• Mitochondria
• None of the above

Which type of cell will make greater demands for DNA?

• 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

The rate at which wastes are produced by a cell partially depends on the cell’s

• surface area
• volume
