Cell Growth

If a cell cannot move enough material through its membrane to survive, then the ratio of its surface area to volume is

• too large.

• just the right size.

• too small.

• growing too quickly.

During interphase a cell grows, duplicates organelles, and

• copies DNA.

• divides the nucleus.

• divides the cytoplasm.

• produces a new cell.

Why do the cells lining the stomach divide more quickly than those in the liver?

• They are much smaller cells.

• They have fewer chromosomes.

• They need much more surface area.

• They undergo more wear and tear.
