7th Grade Chapter 2 Lesson 7

  1. 1. Chapter 2 Lesson 7 Pgs. 68-72 For Student Use Only
  2. 2. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>Plants are producers </li></ul></ul><ul><ul><li>Anything that eats plants are consumers </li></ul></ul><ul><ul><ul><li>Herbivores- plant eating animals </li></ul></ul></ul><ul><ul><ul><li>Carnivores- meat eating animals </li></ul></ul></ul><ul><ul><ul><li>Omnivores- eats both meat and plants </li></ul></ul></ul>
  3. 3. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>The food manufacturing process of plants </li></ul></ul><ul><ul><li>Means “light” + “put together” </li></ul></ul><ul><ul><ul><li>Putting things together with light </li></ul></ul></ul>
  4. 4. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>Plant Parts: </li></ul></ul><ul><ul><ul><li>Chloroplasts: cell part that contains chlorophyll and are the chemical factories </li></ul></ul></ul><ul><ul><ul><li>Chlorophyll: the green pigment of plants </li></ul></ul></ul><ul><ul><ul><li>ATP- (Adenosine Tri-Phosphate)- chemical that is used as energy to create glucose </li></ul></ul></ul>
  5. 5. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>Glucose- Sugar used by plant </li></ul></ul><ul><ul><li>Water and Carbon Dioxide- combine to make Glucose </li></ul></ul><ul><ul><ul><li>Stomota- (tiny holes in leaves) bring in Carbon Dioxide (Stoma= one tiny hole in leaf) </li></ul></ul></ul>
  6. 6. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>6CO 2 + 6H 2 O + Energy= C 6 H 12 O 6 + 6O 2 </li></ul></ul>
  7. 7. Photosynthesis and Respiration <ul><li>Photosynthesis: </li></ul><ul><ul><li>Uses of Glucose: </li></ul></ul><ul><ul><ul><li>Uses to produce proteins, fat, cellulose, and vitamins </li></ul></ul></ul><ul><ul><ul><ul><li>Cellulose- carbohydrate found in the cell wall of the plant </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Vitamins- Originate in plants </li></ul></ul></ul></ul>
  8. 8. Photosynthesis and Respiration <ul><li>Respiration: </li></ul><ul><ul><li>The breaking down of glucose with oxygen to make energy (ATP) for storage </li></ul></ul><ul><ul><li>Opposite of photosynthesis </li></ul></ul><ul><ul><ul><li>Glucose + Oxygen= Carbon Dioxide + Water+ Energy </li></ul></ul></ul>
