Photosynthesis Flashcards
Word equation for photosynthesis
Carbon dioxide + water——(light) glucose + oxygen
What is the symbol equation for photosynthesis
6CO2 + 6H2O ——(light) C6H12O6 + 6O2
Define limiting factor
Anything that stops photosynthesis from happening
Name the limiting factors on photosynthesis
- amount of chlorophyll
- light
- too little carbon dioxide
- temperature
How does light affect photosynthesis
-light provides energy
-intensity of light increases=photosynthesis increases
Only increases up to one point
How does carbon dioxide affect photosynthesis
Only increase up to one point
How does temperature affect photosynthesis
-affects the enzymes involved
-if plant gets too hot, the enzymes denature
—at around 45 degrees C
Name the 5 ways glucose is used
- respiration
- making cellulose
- making amino acids
- stores as oils or fats
- stores as starch
How is glucose used for respiration
Transfers energy from glucose which
How is glucose used for making cellulose
Converted into cellulose for making strong plant cell walls
How is glucose used for making amino acids
Glucose is combined with nitrate ions to make amino acids which are made into protein
How is glucose stored as oils or fats
Turned into lipids for storing seeds
How is glucose stored as starch
Glucose is turned into starch and stored in the roots stems and leaves.
Starch is insoluble—better for storing than glucose
