Biology Chapter 13 Part A

If the length of a cell increases 10 times, its volume increases about:

• 5 times

• 10 times

• 100 times

• 1000 times

The speed with which wastes are produced by a cell depends on the cell's:

• ratio of surface area to volume

• environment

• volume

• surface area

All of the following are problems that growth causes for cells EXCEPT:

• DNA overload

• excess oxygen

• obtaining enough food

• expelling wastes

Compared to small cells, large cells have more trouble:

• dividing

• producing daughter cells

• moving needed materials in and waste products out

• making copies of their DNA

The process by which a cell divides into two daughter cells is called:

• cell division

• metaphase

• interphase

• mitosis

Which of the following is NOT a way that cell division solves the problems of cell growth?

• Cell division provides each daughter cell with its own copy of DNA

• Cell division increases the mass of the original cell

• Cell division increases the surface area of the original cell

• Cell division reduces the original cell's volume

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 enough oxygen and nutrients.

• c. The cell has DNA overload.

• d. Each daughter cell receives its own copy of the parent cell’s DNA.

When during the cell cycle are chromosomes visible?

• a. only during interphase

• b. only when they are being replicated

• c. only during cell division

• d. only during the G1 phase

Which pair is correct?

• a. G1 phase, DNA replication

• b. G2 phase, preparation for mitosis

• c. S phase, cell division

• d. M phase, cell growth

When during the cell cycle is a cell’s DNA replicated?

• a. G1 phase

• b. G2 phase

• c. S phase

• d. M phase
