Zohra's Photosynthesis
Products of Photosynthesis
Increases When The Rate of Photosynthesis Increases
Oxygen
Needed For Respiration For Both Plants & Animals
Test For Oxygen
Place A Glowing Splint at The Mouth of The Test Tube
If It Relights
Oxygen is Present
Sugar (Glucose)
Food For Plants & Animals
Transported From Leaves to Other Parts of The Plant
Excess
Stored As Starch in Storage Organs
Stems
Roots
Test for Starch
Boil The Leaf
To Break Down Cell Walls
Immerse The Leaf in Hot Alcohol
To Remove Green Pigment (Chlorophyll)
Use Iodine
If Starch is Present
Iodine Will Turn Dark Blue
If Starch is Not Present
Iodine Will Remain Reddish Brown
Materials Needed For Photosynthesis Are
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
Test If Chlorophyll Is Needed For Photosynthesis
Use A Bicolored Leaf To Test For Starch
Green Chlorophyll is Present
And Will Test Positive For Starch
Example
Purple Leaves
Red Leaves
Orange Leaves
Green Leaves
The Green Chlorophyll is Hiding Under These Colors
Green Chlorophyll is Not Present
Example
White Leaves
Yellow Leaves
And Will Test Negative For Starch
Traps Light
When The 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, Pluck 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
