1. Name _________________________________________ Date ___________________ Period _________ QUIZ: PLANTS • Directions: Put all your responses directly on this quiz sheet. For multiple choice questions, place the letter of your response on the line provided. Think about all the examples, demonstrations, and pictures with which we’ve dealt in class. Remember to take your time and read each question carefully. Once you have made your response, make sure that it addresses what the question is asking. Before you turn in your quiz, give a big hug to the person to your right. Leave no questions blank, as they will be marked off at twice the rate of a wrong answer. Good luck, have fun, and learn much! • 0. What is the best flavour of ice cream? • 1. What is the overall purpose of photosynthesis? • 2. Why might a plant want to open its stomata only at night? • Conserve water B. Perform the Calvin Cycle Backwards • C. Excrete extra carbon dioxide D. Make sure to balance pressure in the leaf _________ • 3. How does water move up a plant? • 4. What is pumped INTO the thylakoid space during the light reactions? • A. Protons B. Beef C. Hadrons D. ATP _________ • 5. Stuart puts his plant in a jar that is filled with only oxygen. What will happen to his plant? • A. The plant will continue to do photosynthesis, because it has all the oxygen it needs. • B. The plant will die because oxygen absorbs sunlight and shoots off an electron. • C. The plant will start converting the oxygen to carbon dioxide using the Krebs cycle. • D. The plant will start adding oxygen to RuBP instead of carbon dioxide. _________ • 6. The Calvin cycle takes in ___________ and produces ___________. • A. Orphans; superheroes. • B. Sugar; ATP. • C. Carbon dioxide; three-carbon sugars • D. Carbon triiodide; glucosamine _________ • 7. What is one advantage and one disadvantage of plants being pollinated by wind? • 8. List one way that plants can spread their seeds and one way that they can be pollinated.

2. 9. In the drawing to port, what is chlorophyll doing? 10. After chlorophyll shoots up an electron, what charge will it have? 11. Chlorophyll would simply fall apart every time sunlight hit it, if it shot off electrons and never replaced them. Where does chlorophyll find replacement electrons? WHY IS THIS IMPORTANT FOR HUMANS? (hint: maybe this process makes something that humans need) 12. What is released as a by-product of the light reactions? A. ATP B. NADPH C. Xylem fluid D. Oxygen _________ 13. Plants and some bacteria can use the process of photosynthesis to make their own food. Ergo, we can call these types of organisms: A. Awesome, dude B. Autotrophs C. Heterotrophs D. Mesotrophs _________ 14. Solutions with a high concentration of H+ (protons) are very acidic (have a low pH). Compare the pH of the thylakoid space when there is sunlight present, and when it is dark. (hint: think about the light reactions and where protons are being pumped). You may write, draw, or both.
