Be sure to note the enzymes/molecules used, the amount of ATP used/produced, and any specialized organelles 2 Based upon what you know about photosynthesis, which reactant is most limited in plants that live in deserts? How do you think plants may overcome this limitation? 3 Based upon what you know about osmosis and diffusion, why do you think plants convert glucose into starch for the energy-storing molecule? 4 The overall equation for photosynthesis is 6CO2+12H20-->C6H12O6+6O2+6H2O If either of the reactants is limiting, photosynthesis grinds to a stop a. Explain how CO2 is transported from the atmosphere to the site of photosynthesis, including how this transport is regulated b. What is the first thing that happens to Co2 when it reaches the site of photosynthesis? c. Explain how H20 is transported from the soil to the site of photosynthesis d. Which mechanism is responsible for the majority of water transport? e. What is the purpose of the water in photosynthesis? 5 Where do Ca and C3 pathways undergo in C4 plant, respectively? What is relat the both pathways? 6 How does greenhouse effect impact plants with different photosynthetic pathways? 7 Why Ca plants are more effective in photosynthesis than C3 plants? 8植物在长期黑暗中能不能进行暗反应?为什么? 9比较C3植物与C4植物的异同。 10叙述光合作用中光反应和暗反应的关系 11光合磷酸化与氧化磷酸化的过程如何?它们之间有什么区别和相似之处? 12为什么说光合作用与硝酸还原的关系是间接的? 13光呼吸有什么生理意义?如何控制光呼吸? 14在生产实践中如何利用光补偿点提高光合产量?5 光饱和现象 6 光合作用中心 7 吸收光谱 8 光合色素 9 暗反应 10 光合产物 11 光呼吸（photorespiration） 五 解释现象 1 光合作用中的叶子突然停止光照会引起 3—磷酸甘油酸含量上升。 2 秋天叶子变红。 3 作物合理密植会增产。 4 肉质类植物适应热带干旱条件。 5 离体叶绿素有明显的荧光现象，而活体植物叶子荧光现象非常弱。 六 问答题 1 Compare and contrast photosynthesis and cellular respiration.
