Multiple Choice

Calculate the surface area, volume and SA:Vol ratio for the cube

• 6:1

• 2:1

• 3:1

• 1.5 : 1

Remember:

As cells grow, the SA:Vol ratio decreases

Multiple Select

Select all of the below processes that are part of the cell cycle.

• Mitosis

• Meiosis

• Interphase

• Cytokinesis

Remember

Multiple Choice

Which of the below processes is the longest phase of the cell cycle?

• Mitosis

• Meiosis

• Interphase

• Cytokinesis

Multiple Choice

Using the image, identify the structure C

• Centriole

• Microtubule

• Chromatid

• Centromere

Multiple Choice

Using the image, identify the structure D

• Centriole

• Microtubule

• Chromatid

• Centromere

Multiple Select

Which of the below statements are true about cancer cells. Select all that apply.

• They spend less time in interphase

• They lose their control in dividing during cell cycle

• They stay mostly paused/stopped at the S phase of the cell cycle

• They grow rapidly and absorb nutrients needed by other surrounding cells

Multiple Select

Which two components combine to control the cell cycle/ cellular reproduction process?

• Cyclins

• Carcinogens

• Chromosomes

• Cyclin-dependent kinases

Remember:

Proteins called cyclins bind to enzymes called cyclin-dependent kinases (CDKs) in the stages of interphase and mitosis to start the various activities that take place in the cell cycle. 

Multiple Choice

Which of the following statements best defines apoptosis?

• It is harmful for the cells

• It is called programmed cell death

• It is known as uncontrolled growth of cells

• It is caused by a failure in the regulation of cell cycle

Multiple Select

Select all that apply. How do cancer cells kill organisms?

• Killing individual cells

• Destroying tissue function

• Crowding out normal cells

• Allowing individual cells to grow too large
