photosynthesis

• 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
