Questions and Answers

What is a primary reason cells prefer to divide instead of continuing to grow indefinitely?

  • Cells can only absorb nutrients if they are small. (correct)
  • Larger cells can produce more energy.
  • The surface area to volume ratio becomes unfavorable. (correct)
  • Larger cells have more DNA to meet their needs.
  • How is the surface area to volume ratio obtained?

  • By dividing the surface area by the volume. (correct)
  • By subtracting the volume from the surface area.
  • By adding the surface area and the volume.
  • By multiplying the surface area by the volume.
  • What happens to the surface area to volume ratio as cells increase in size?

  • It remains constant regardless of size.
  • It decreases, complicating nutrient exchange. (correct)
  • It fluctuates based on the type of cell.
  • It increases, making nutrient exchange easier.
