1. Answer the following questions using the diagram to the right
What is the name of structure G and what process takes place there?
Mitochondria (cellular respiration)
b. What is the name of structure B and what process takes place there?
chloroplasts (photosynthesis)
c. What is the name of structure F and what is the function of this structure?

(stores water)

3. 2. Complete the chart: Cell structure Process Function Equation
mitochondria 
Cellular respiration
Creates energy (ATP) from sugars
C6H12O6 + 6O2 → 6CO2 + 6H2O  
chloroplast
photosynthesis 
Transforms light energy into chemical energy (sugar) 
6CO2 + 6H2O →C6H12O6 + 6O2

adenine ribose phosphate groups

10. 17. How are cellular respiration and photosynthesis almost opposite processes?
Each makes what the other needs (a cycle)
18. How is energy stored in the ATP molecule? How is it released?
Energy stored in phosphate bonds
Energy released when bond holding 3rd phosphate group breaks

11. 19. Where in the chloroplast is chlorophyll found?
 in the thylakoids
20. What is chemosynthesis and where does it occur?
 making sugars using chemicals instead of light (found at deep sea thermal vents at bottom of ocean)

called
producers (autotrophs)
23. Organisms that can make their own food are called? consumers (heterotrophs)
