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

Flashcards
Cell Growth Limit
Cell Growth Limit
Cells divide instead of continuously growing larger because a larger cell struggles to move nutrients and waste products across its membrane efficiently.
Surface Area to Volume Ratio
Surface Area to Volume Ratio
A ratio comparing the surface area of a cell to its volume
Surface Area to Volume (ratio)
Surface Area to Volume (ratio)
As cells get larger, their volume grows faster than their surface area.
