photosynthesis

Cards (10)

  • Examples of limiting factors.
    Carbon dioxide concentration, light intensity, temperature
  • Where do plants get their energy?
    sun
  • Word equation for photosynthesis
    Carbon dioxide + water -> glucose + oxygen
  • what absorbs the energy required for photosynthesis?
    chlorophyll
  • In what part of the cell does photosynthesis take place?
    in chloroplasts
  • Which type of reaction is photosynthesis?
    endothermic
  • What can the glucose made during photosynthesis be used for?
    stored as starch for later
    respiration
  • How do plants get the carbon dioxide required for photosynthesis?
    It diffuses from the air into the leaves via stomata
  • What makes starch a useful long term storage molecule?
    it is insoluble in water
    it is compact
    it can easily be broken down when needed
  • What are the main uses of glucose in plants?
    cellular respiration - break down the glucose to release energy
    make cellulose - which are used to make strong cell walls
    make starch - which are used to store glucose for a later time
    make amino acids - which are used to make proteins
    make lipids - these store the energy as fats or oils for later use
