Experiments Expected Results

Question 1

Experiment to show light is necessary for photosynthesis (card clipped on leaf)

Answer 1

Areas covered by paper cannot photosynthesise and produce starch = different colouration of leaf

Question 2

Experiment to show chlorophyll/chloroplasts is needed for photosynthesis

Answer 2

Different colouration of starch test dependent on concentration of chloroplasts

Question 3

Experiment to show without co2 starch cannot be produced during photosynthesis/ the plant cannot store energy

Answer 3

No leaves show starch production

Question 4

Experiment to show more carbon is used in the chemical process so oxygen is released from co2

Answer 4

Normal starch production
