What is the equation for Photosynthesis |
Carbon dioxide + water ~ Glucose + oxygen |
|
|
Glucose |
Used for respiration Converted to starch for storage Converted to amino acids to make proteins for growth |
|
|
Oxygen |
Used for respiration |
|
|
Testing a leaf for starch |
Leave in boiling water - stops chemical reactions, kills leaf Put in boiling ethanol - remove chlorophyll Dip into hot water - softens leaf, ethanol makes it brittle Put on white tile, add iodine solution - test for starch - colour change yellow brown-blue black indicates presence of starch |
|
|
Destarch |
Place the plant in a dark cupboard for at least 2 days. If starch is present at the end of the experiment it was made throughout |

Testing for carbon dioxide with hydrogen carbonate indicator |
Increasing Co2 Yellow Remaining Co2 Red Decreasing Co2 Purple |
|
|
Compensation point |
The rate of photosynthesis = the rate of respiration |
