Put a STAR next to any question you could not answer without using your notes.
CLG 3.2.1 A: Organelles In the Venn Diagram below, place the following words in their correct location to show if it applies to plant cells, animal cells, or both. Ribosomes Lysosomes Cell Membrane Cell Wall Mitochondria
Chloroplast Onion Cells Human Cheek Cells Perform Respiration One Large Vacuole Many small Vacuoles Perform Photosynthesis Nucleus Plant Cells Both Match the following functions to the correct organelle. 1. Nucleus: ___________ A. Capture light energy and converts it to chemical energy in plants 2. Mitochondria: ________ B. Directs cell activities and contains DNA 3. Chloroplast: ________ C. Releases energy in the form of ATP 4. Vacuole: ________ D. Site of protein synthesis 5. Cell Membrane: _______ E. Controls what enters and exits the cell 6. Cell Wall: ______ F. Short, hairlike fibers that help the cell move 7. Ribosomes: ________ G. Whip-­‐like tail that helps the cell move 8. Cilia: ________ H. Stores water, food, and waste 9. Flagella: ________ I. Found outside the cell membrane; adds extra protection and support to plants 10. Pseudopodia: ________ J. Moves the cell by reshaping itself CLG 3.1.3 A: Photosynthesis/Chemosynthesis 1. What do plant cells need to perform photosynthesis (the reactants)? 2. What do plant cells make in photosynthesis (the products)? 3. Write the overall chemical equation for photosynthesis in words and symbols: Animal Cells Name:_____________________________________ Period:______ Date:__________________ 4. Which of the following is not used in photosynthesis? A) Carbon Dioxide B) Water C) Oxygen D) Sunlight 5. Autotrophs can store energy in the form of: A) Oxygen B) Nucleic Acids C) Water D) Carbohydrates 6. What process provides most of the oxygen found on Earth? A) Chemosynthesis B) Photosynthesis C) Aerobic Respiration D) Anaerobic Respiration 7. If the amount of carbon dioxide in the atmosphere increases, will the Elodea plants grow MORE or LESS? (Circle One) What process explains this? A) Chemosynthesis B) Photosynthesis C) Aerobic Respiration D) Anaerobic Respiration 8. Some bacteria live in environments where sunlight cannot reach them. However, they are still autotrophs because they convert inorganic compounds into carbohydrates. What process explains how they can do this? A) Chemosynthesis B) Photosynthesis C) Aerobic Respiration D) Anaerobic Respiration 9. In what cell organelle does photosynthesis occur? _________________________________ CLG 3.1.3 B: Cellular Respiration/Carbon Cycle 1. What is required for cellular respiration to occur (the reactants)? 2. What is made from cellular respiration (the products)? 3. Write the overall equation for cellular respiration in words and symbols. 4. What is the difference between aerobic and anaerobic respiration? 5. List two examples of heterotrophs. 6. For the following processes, say whether they increase (I) or decrease (D) the amount of carbon dioxide in the air. A) Burning Fossil Fuels: ________ B) Cellular Respiration: ________ C) Decomposition (animals rotting): ___________ D) Photosynthesis: __________ 7. True or False: Plants undergo cellular respiration. 8. True or False: Cellular respiration requires light to complete the reaction. 9. What process releases energy from sugars? A) Chemosynthesis B) Photosynthesis C) Cellular Respiration D) Decomposition 10. In what cell organelle does cellular respiration occur? ______________________________
