PHOTOSYNTHESIS Final Exam Questions and Graded Answers, 100 %
Guaranteed
What is the word equation for photosynthesis? - ✔✔Carbon dioxide + water + light →
glucose + oxygen
What type of reaction is photosynthesis? - ✔✔An endothermic reaction
What is the role of chlorophyll in photosynthesis? - ✔✔Chlorophyll traps sunlight energy
needed for the reaction.
What happens to the rate of photosynthesis as temperature increases? - ✔✔The rate of
photosynthesis increases until it reaches 45°C, after which it drops to zero.
What is the limiting factor in photosynthesis? - ✔✔The factor that stops the reaction from
going any faster.
How does carbon dioxide concentration affect photosynthesis? - ✔✔As CO₂ concentration
increases, the rate of photosynthesis increases until a certain point.
What effect does light intensity have on photosynthesis? - ✔✔As light intensity increases,
the rate of photosynthesis increases until it reaches a saturation point.
What happens to the enzymes controlling photosynthesis at high temperatures? - ✔✔They
are destroyed, causing the rate of photosynthesis to drop to zero.
What is produced as a result of photosynthesis? - ✔✔Glucose and oxygen
What is the significance of photosynthesis in terms of energy? - ✔✔It converts energy from
sunlight into chemical energy in the form of glucose.
