• Water

• Light Energy

• Oxygen

Which of the following is NOT a use of the carbohydrates produced during photosynthesis?

• Energy Store

• Cell Wall Building

• Protein Synthesis

• Insect Attraction

What is the balanced chemical equation for photosynthesis?

• O2 + CO2 -> H2O + C6H12O6

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + O2 -> CO2 + H2O

Which structure in a leaf is responsible for the exchange of gases during photosynthesis?

What is the pathway of carbon dioxide from the atmosphere to chloroplasts in a leaf?

• Atmosphere -> Spongy Mesophyll -> Cuticle -> Chloroplasts

• Atmosphere -> Guard Cells -> Vascular Bundles -> Stomata

• Atmosphere -> Air Spaces -> Leaf Mesophyll Cells -> Chloroplasts

• Atmosphere -> Upper Epidermis -> Lower Epidermis -> Palisade Mesophyll

Which factor is responsible for controlling the rate of photosynthesis up to a certain temperature beyond which the rate decreases?

What is the main purpose of air spaces in the leaf structure?

• Nutrient Absorption

• Water Storage

• Photosynthesis

• Gas Exchange
