During photosynthesis light energy is …
Absorbed by a pigment called chlorophyll
Chlorophyll is found in …
The chloroplasts of plant cells
There is no photosynthesis because …
No glucose and no starch
There is photosynthesis because …
There is glucose and starch
Leaf Experiment - Photosynthesis :
Blue/Black
Leaf Experiment - No Photosynthesis :
Orange/Brown
The glucose made by photosynthesis is stored …
In the form of starch
The production of starch can be tested using …
Iodine solution
The need for carbon dioxide can be tested using …
Soda lime
What does the soda lime does what …
It traps the carbon dioxide by a chemical reaction and removes it from the air.
Alternatively the consumption of carbon dioxide can be tested using …
Lime water
Experiment Light Is Needed :
The covered up art of the leave will not make oxygen so it will use up the starch deposit, so it will remain brown in iodine
Experiment Chlorophyll Needed
The areas with chlorophyll will photosynthesis so that it will change colour in iodine. The area without chlorophyll doesn’t photosynthesis so it doesn’t change in colour.
Experiment Oxygen is Needed:
Elodea gives off oxygen bubbles. We trap the oxygen and bring the test tube up. It will relight a burning splint, as the test tube is full of oxygen
Leaf function : carry out …
