A chef cuts his finger while slicing tomatoes for the night’s signature recipe. Upon injury, the chef’s cells divide....
Scenario 1
Three reasons why cells divide:
1. Too BIG
(surface area to volume ratio is small; inefficient osmosis & diffusion)
2. To replace damaged or dead cells
3. For growth and development (embryo)
Which one of these reasons relates to Scenario 1 and why?
