Chapter Test
Multiple Choice (+2 Points Each)
Write the letter that best answers the question or completes the statement on the line provided.
_____ 1. Compared to small cells, large cells have more trouble
a. dividing.
b. producing daughter cells.
c. storing needed materials and waste products.
d. moving needed materials in and waste products out.
_____ 2. Which of the following happens when a cell divides?
a. The cell’s volume increases.
b. It becomes more difficult for the cell to get get rid of wastes.
c. Each daughter cell receives its own copy of the parent cell’s DNA.
d. It becomes more difficult for the cell to get enough oxygen and nutrients.
_____ 3. A multicellular organism begins life as a single cell—a fertilized egg with a complete set of chromosomes.
This cell divides to become two cells, then four cells, eight cells, and so on. Which of the following
statements best describes what happens during this process?
a. Chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
b. Chromosomes are divided evenly during cell division so that each new daughter cell has an equal share
of the original set.
c. Chromosomes are stored in the original cell to direct the division of all daughter cells, which do not
have their own chromosomes.
d. Chromosomes are randomly distributed during cell division so that some new cells have partial sets
while others have complete sets.

a. G1 phase
c. M phase
b. G2 phase
