• Only Heterotrophs
• Autotrophs and Heterotrophs

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

Plants need ________ for photosynthesis

• oxygen
• soil
• carbon dioxide
• sugar

Chlorophyll absorbs a higher percentage of _____ and _______ light.

• purple and green
• red and blue
• black and orange
• yellow and green

Which statement about photosynthesis is correct?

• Plants get the energy they need for photosynthesis from water.
• Plants get the energy they need for photosynthesis from soil.
• Plants get the energy they need for photosynthesis from sunlight.
• Plants do not require energy to perform photosynthesis.

Where do the light-dependent reactions occur? 

• thylakoid membrane
• stroma
• mesophyll
• mitochondria

Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis? 

• The light-dependent stage
• The light-independent stage (The Calvin Cycle)
• The electron transport chain
• ATP formation

Use the diagram to answer the question. Which chemical is an electron carrier molecule?

• H₂O
• carbon dioxide
• NADP⁺
• oxygen

Is ADP or ATP more like a fully charged battery, and why?

• ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
• ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
• ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.

In which  organelle does photosynthesis occur?

• mitochondria
• stomata
• xylem
• chloroplast
