photosynthesis (B.25)

• Name the two reactants in photosynthesis

  Carbon dioxide and water
• Name the two products formed in photosynthesis

  oxygen and glucose
• word equation for photosynthesis

  Carbon dioxide + water -> oxygen and glucose
• symbol equation for photosynthesis

  CO2 + H20 -> 02 +C6H12O6
• describe what happens to the rate of photosynthesis as temperature increases

  rate increases and then decreases
• describe what happens to the rate of photosynthesis as light intensity increases

  rate increases and then remains constant
• describe what happens to the rate of photosynthesis as carbon dioxide increases

  rate increases and then remains constant
• Define limiting factor

  A factor that directly affects the rate for photosynthesis on its own, regardless of the level of other factors.
• Name the plant used to investigate the effect of different factors on rate of photosynthesis

  Pondweed
• How can you calculate the rate of photosynthesis of an aquatic plant?

  count the number of O2 bubbles produced in a minute
• how can you more accurately calculate the rate of photosynthesis of an aquatic plant?

  record volume of gas produced (using gas syringe)
• which cells are adapted for increased photosynthesis ?

  Palisade cells
• How are palisade cells adapted for increased rates of photosynthesis

  lots of chloroplasts (and chlorophyll )
• three limiting factors for photosynthesis

  1)Carbon dioxide concentration 2)Temperature 3)Light intensity
