Cell Growth and Cell Size

To stay alive, a cell needs materials to move in and out across its membrane. As a cell grows bigger, its volume increases _____ than its surface area. At a certain point, the cell’s volume would be _____ compared to the area available for materials to move in and out.

• faster / too small

• faster / too large

• slower / too small

• slower / too large

Checks for cell size, nutrients, growth factors, and DNA damage.

• G1 checkpoint

• G2 checkpoint

• Spindle checkpoint

• DNA polymerase

During most of interphase, DNA is found in a relaxed form called

• chromosome

• centromere

• centriole

• chromatin

The cell cycle is regulated by this

• cyclins

• stem cells

• cyclin-dependent kinases

• both cyclins and cyclin-dependent kinases

Some scientists name the stage where cells carry out their normal functions but are unlikely to divide. The name they give this stage is _________.

• G0

• G1

• G2

• G3

Why do cells remain small in size? (Select ALL that apply)

• Maintain high surface area to volume ratio

• More energy efficient

• Easier to destroy if something goes wrong

• Smaller cells divide quicker

The growth phase of the cell cycle is called

• Interphase

• Telophase

• Prophase

• Anaphase

What is the primary reason cells remain small in size?

• To maintain a high surface area to volume ratio

• To conserve energy

• To avoid mutations

• To increase DNA content

Which phase of the cell cycle is primarily responsible for cell growth?

• G1 phase

• S phase

• G2 phase

• M phase
