Photosynthesis & Cellular Respiration
•
They are the reverse of each other.
• Common Misunderstanding:
• Photosynthesis occurs only in plant cells, and some in Protista
• No it does not occur in animal cells
• Cellular respiration occurs in all eukaryotes!
• The source of the glucose is what varies.
• Plants – autotrophs
• Animals – heterotrophs
• Fungi – heterotrophs  Detritivores

Follow-up Questions:
1. Compare the time it took the bromothymol blue
solution to change color before exercise and after
exercise. Explain why there was a difference.
2. In this investigation, we measured the amount of
carbon dioxide produced to find the rate of
cellular respiration. What else could we measure
to find out the rate of cellular respiration?
