what is photosynthesis?

• what do plants use for their source of energy?

  light
• what do plants do to trap photosynthesis?

  plants use light energy to trap photosynthesis
• what reaction does photosynthesis take in energy?

  endothermic reaction
• what is an endothermic reaction?


  photosynthesis takes in energy
• where does photosynthesis occur?

  leaf
• what is the green chemical the leaf contains?

  chlorophyll
• what can chlorophyll do?

  absorb light energy
• what is the photosynthesis word equation?

  carbon dioxide + water --> light, chlorophyll glucose + oxygen
• what is the photosynthesis chemical formula/ symbol equation?

  Co2 + H2o --> C6H1206 + O2
• is the photosynthesis balanced or not balanced equation?

  balanced
• if light intensity is zero, what will be the rate of photosynthesis?

  zero
• what do plants need to carry out photosynthesis?

  light
• as you increase light intensity, what happens to the rate of photosynthesis?

  increases
• whqat happens when you keep increasing the light intensity?

  the rate of photosynthesis no longer increases/ come to an end
• sometimes, why is there patches of chlorophyll on a leaf?

  the leaves traps less light energy than normal leaves (they will have a lower rate of photosynthesis)
• what happens to photosynthesis when the temperature increases?

  enzymes involved in photosynthesis work faster so the rate increases
• what happens if you keep increasing the temperature during photosynthesis?

  the enzymes will denature and the rate of photosynthesis falls
