Nate's Photosynthesis
Products of photosynthesis
Sugar
Food for Plants and animals
Test for starch
Boil the leaf
To break down cell walls
Immerse the leaf in hot alcohol
To remove green pigment
Use iodine
If starch is present
Iodine will turn dark blue
If starch is not present
Iodine will remain reddish brown
Transported from leaves to other parts of the plant
Excess
Stored as starch in storage organs
Stems
Roots
increases when the rate of photosynthesis increases
Oxygen
Test for oxygen
Place a glowing spilt at the mouth of the test tube
If it relights
Oxygen is presented
Needed for respiration for both plants and animals
Materials needed for photosynthessis
Water
Carbon dioxide
test if carbon dioxide is needed for photosynthesis
Not the same when testing if carbon dioxide is present
Lime water test
Chlorophyll
Traps light
When light intensity increases, rate of photosynthesis increases
Test if light is needed for photosynthesis
Cover part of the leaf with black paper
After a few hours, plluck the leaf from the plant and test for starch
Part of the leaf exposed to light
Positive for starch
Part of the leaf under the black paper
Negative for starch
Test if chlorophyll is needed for photosynthesis
Green chlrophyll is present
Examples
Purple leaves
Red leaves
Orange leaves
Green leaves
And will test positive for starch
Green chlorophyll is not present
And will test negative for starch
Example
White leeves
Yellow leaves
