  1. Photosynthesis & Respiration

    Slide 1 - Photosynthesis & Respiration

  2. What is Photosynthesis?

    Slide 2 - What is Photosynthesis?

    • Photosynthesis is a chemical reaction which occurs in plants and some algae.
    • Photosynthesis takes carbon dioxide, water, and light energy and produces glucose and oxygen.
    • Photosynthesis takes place in the chloroplasts of plants
  3. What is the equation for the chemical reaction of photosynthesis?

    Slide 3 - What is the equation for the chemical reaction of photosynthesis?

  4. What is the equation for the chemical reaction of photosynthesis?

    Slide 4 - What is the equation for the chemical reaction of photosynthesis?

    • Six molecules of carbon dioxide react with six molecules of water to form 1 molecule of glucose and six molecules of oxygen.
  5. Why is this important to us?

    Slide 5 - Why is this important to us?

    • We cannot make our own food (glucose, energy), we must get our food from plants.
    • Plants are the first step in the food chain.
    • The oxygen released during photosynthesis is necessary for all living things.
  6. What is Cellular Respiration?

    Slide 6 - What is Cellular Respiration?

    • Cellular respiration is also a chemical reaction.
    • The chemical energy created in photosynthesis must be transformed so it is useful to the organism.
  7. What is the chemical equation for cellular respiration?

    Slide 7 - What is the chemical equation for cellular respiration?

  8. Describe Cellular Respiration

    Slide 8 - Describe Cellular Respiration

    • The breakdown of glucose molecules to release energy
    • Takes place in all living things
