1 THS General Biology Unit 4 Exam Review Content: Photosynthesis & Cellular Respiration You should be able to complete all of the following tasks, objectives, and answer any questions, without the use of any notes or resources, in order to be successful on the quiz. Good Rule of Thumb : If you can have a conversation about it, then you know and understand it. This Exam: Is 60% of your class grade. Has 13 difficult multiple choice questions. o 4 questions on photosynthesis. o 4 questions on cellular respiration o 2 questions on the connection between photosynthesis and cellular respiration. o 3 questions on ATP and energy cycling. Has 1 difficult application, written response question. o Interrelatedness of photosynthesis and cellular respiration.

2 Photosynthesis Content: 1. Define photosynthesis. 2. Identify the full chemical equation for photosynthesis. 3. What is the purpose of photosynthesis? 4. Discuss how energy is transferred and converted during photosynthesis. Cellular Respiration Content 5. Define cellular respiration. 6. Identify the full chemical equation for cellular respiration. 7. What is the purpose of cellular respiration? 8. Discuss how energy is transferred during cellular respiration. Other Content: 9. What is ATP? 10. What is chemical potential energy? 11. What is electromagnetic energy? 12. What is kinetic energy? 13. How do photosynthetic organisms rely on non-photosynthetic organisms? 14. How does energy move through the environment?

3 BIG Written Question to Plan Ahead for: (We will NOT go over these answers in class. As a student, you are advised to practice writing out your responses ahead of time, and asking your teacher for any clarification if necessary.) Background Information: Scientists were trying to study the relationship/s between plants and animals in an experiment. The scientists set up the experiment and in one specific set-up, 1 small aquatic plant and 3 aquatic snails were all placed together in an aquarium tank. The organisms were given fresh, pure distilled water, and were provided a regular source of UV sunlight (through a sunlamp). After letting the plant and snails live together for 24hours, the scientists came back to record data and observations. Surprisingly they found that the plant was still living, but 2 out of the 3 snails had died.

4 The following includes a variety of data collected throughout the experiment: Experimental Set-Up SET-UP A 1 Aquatic Plant (in water with sunlight) SET-UP B 1 Aquatic Animal (in water with sunlight) SET-UP C 1 Aquatic Plant (in water without sunlight) SET-UP D 1 Aquatic Animal (in water without sunlight) SET-UP E 1 Aquatic Plant and 1 Aquatic Animal (in water with sunlight) SET-UP H 1 Aquatic Plant and 3 Aquatic Animals (in water with sunlight) Bromothymol Blue Results Blue Yellow Yellow Yellow Green Yellow-Green

5 Below is data collected from a lab conducted on an AQUATIC PLANT: Distance from Sun-Lamp (cm) Oxygen Gas Produced Oxygen Gas Consumed/Used Carbon Dioxide Gas Produced Carbon Dioxide Gas Consumed/Used Below is data collected from a lab conducted on an AQUATIC ANIMAL: Distance from Sun-Lamp (cm) Oxygen Gas Produced Oxygen Gas Consumed/Used Carbon Dioxide Gas Produced Carbon Dioxide Gas Consumed/Used

6 CER WRITING PROMPT: Use relevant pieces of data from the experiment, along with your understanding of Cellular Respiration and Photosynthesis, to EXPLAIN WHY THE 1 PLANT SURVIVED THE EXPERIMENT, BUT 2/3 OF THE SNAILS DIED.
