    Unit 4 Test Cellular Respiration & Photosynthesis

    1. Write down the question (s) you missed.
    2. Write down the answer.
    3. Write down any ‘notes’ or help you need to be able to answer the question in the future.


    This is not optional.

    You cannot retake your test without this assignment.

    Test retakes / makes ups are Friday 2.14.20 & 2.21 during walk time tutoring at 2:30 in room 905.

    If you do not come to one of these retake sessions, you can have your parent make arrangements to bring you in early or to pick you up after school.

    Cellular Respiration & Photosynthesis End of Unit Assessment 2020         Mrs. Albert

    1. What is the chemical equation for Photosynthesis?
      1. 6CO2 + 6H2O + light energy = C6H12O6 + 6O2
      2. CO6 + H6O + light energy = C6H12O6 + 6O2
      3. C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 or 38 ATP.
      4. 6CO2 + 6H2O + light energy = 6CO2 + 6H2O + 36 or 38 ATP.


    1. What is the main source of energy for most living things?
      1. Food
      2. Water
      3. Sun light
      4. Oxygen


    1. Which of the following is true about chemical reactions?
      1. In a chemical reaction, substances called reactants are changed into other substances called products.
      2. You can change one element into another in a chemical reaction
      3. Only products are used in chemical reactions
      4. Substances cannot be changed due to chemical reactions


    1. Photosynthesis means:
    2. the green material in plants that traps energy from sunlight and uses it to break down water molecules into atoms of hydrogen and oxygen.
    3. in a plant, the growth tissue that produces the xylem and the phloem.
    4. the process by which green plants use chemicals from the environment and energy from the sun to make their own food.
    5. using glucose to make energy


    1. What is the function of stomata?
      1. Release CO2
      2. Absorb water
      3. Release O2, absorb CO2
      4. Absorb O2


    1. Glucose and oxygen are turned into large amounts of ATP in which organelle?
    2. Nucleolus
    3. Mitochondrion
    4. Nucleus
    5. Chromatin


    1. Glycolysis, Krebs Cycle and Electron transport chain are steps in what process:
      1. Photosynthesis
      2. Aerobic cellular respiration
      3. Transpiration
      4. Water cycle


    1. What three things do plants need to make food?
      1. Glucose, oxygen, water
      2. Water, oxygen, light energy
      3. Water, carbon dioxide, light energy
      4. Water, ATP, carbon dioxide


    1. In which process or step of cellular respiration is the greatest amount of ATP released?
      1. Krebs & Glycolysis
      2. Glycolysis
      3. Electron Transport Chain
      4. Krebs cycle


    1. CO2 is the chemical formula for:
      1. Oxygen Hydroxide
      2. Water
      3. Carbon dioxide
      4. Carbon


    1. C6H12O6 is the chemical formula for:
      1. Water
      2. Photosynthesis
      3. Glucose
      4. Carbon Dioxide


    1. Claim, Evidence Reason:

    Claim:  If there were no plants, there would be no photosynthesis; if there was no photosynthesis there would be no life, or very different types of life, on Earth.

    Evidence:  Plants take up CO2 & H2O to make Glucose, and in the process release Oxygen into the atmosphere.


    1. Most organisms require oxygen to carry our cellular respiration, and they get rid of carbon dioxide in the process
    2. Plants make the carbon dioxide that animals need to make glucose
    3. All living things need carbon dioxide
    4. Only plants carry out cellular respiration

    The following Questions 13 - 18 ARE NOT multiple choice!!  Bubble in the letter that answers the question.

    1. In the following diagram, which letter represents the release of O2: A, B, or C
    2. In the following diagram, which letter represents the absorption of C02: A, B, or C









    1. In the following diagram, which letter represents the Mitochondrion : A, B, or C


    1. In the following diagram, which letter represents Glycolysis: A, B, or C








    1. In the following diagram, which letter represents chloroplasts: A B or C ?                             










    Use the Diagram Below to answer questions 18 - 19                                                                                              








    1. Which side of the diagram represents photosynthesis, A or B?

    1. Chemical reactions are either endothermic or exothermic. What is the difference?
      1. Exothermic reactions release energy, endothermic reactions absorb energy
      2. Exothermic reactions absorb energy, endothermic reactions release energy
      3. Exothermic reactions are always fast, endothermic reactions are always slow
      4. Exothermic reactions are always slow, endothermic reactions are always fast
