What to Focus On

  • Green plants are autotrophs.
  • Photosynthesis needs water, carbon dioxide, chlorophyll, and sunlight.
  • Photosynthesis occurs in mesophyll cells and chloroplasts.

  • Sunlight splits water during photosynthesis.
  • Oxygen comes from the hydroxyl ion.
  • Hydrogen ions combine with carbon dioxide to form glucose.

  • Glucose and oxygen are the end products of photosynthesis.
  • Glucose may be stored as starch.
  • At night starch changes back to sucrose for transport.

Common Mistakes to Avoid

Photosynthesis happens in every part of the plant.

Chlorophyll and chloroplast are the same thing.

Stomata are found only on the upper surface of leaves.
