Final answer:
Cheek cells would contain a greater amount of mitochondria compared to onion cells because animal cells have a higher metabolic rate and energy demand. Unlike plant cells, animal cells do not have chloroplasts, so their energy production is solely reliant on mitochondria.
Step-by-step explanation:
The cheek cells would contain a greater amount of mitochondria compared to the onion cells. Mitochondria are responsible for producing ATP, the main energy currency of the cell. Cheek cells are animal cells, which have a higher metabolic rate and energy demand compared to plant cells. Therefore, they require more mitochondria to meet their energy needs.
In addition, animal cells do not have chloroplasts like plant cells, which are the organelles responsible for photosynthesis. Since photosynthesis is not needed in animal cells, the energy production is solely reliant on mitochondria.
To summarize, cheek cells would contain a greater amount of mitochondria because animal cells have a higher metabolic rate and energy demand compared to plant cells, which do not have chloroplasts for photosynthesis.
