exam Flashcards
Where does photosynthesis occur
leaves , palisade layer/mesophyll , chloroplasts
How does oxygen/carbon dioxide get into leaves
Diffusion through the stomata (lower epidermis)
What is diffusion
Movement from high to low concentration
State the three limiting factors for photosynthesis
Temperature , light intensity, carbon dioxide concentration
What is the independent variable
The thing you change
What is the control variable
The thing u keep the same
What is the dependant variable
The thing measure
Independent variable of photosynthesis practical and where does it go
Light intensity , bottom of the graph
What is the control variable of the photosynthesis practical
Same type and volume of pond weed
What is the dependant variable of the photosynthesis practical
Number of/amount of bubbles
How to make a test more accurate
(3 ways)
Repeat 3x , remove anomalies , calculate a mean
Photosynthesis word equation
Water + carbon dioxide —-> glucose + oxygen
Photosynthesis chemical equation
6CO(2) + 6H(2)O (light)—>(chlorophyll) C(6)H(12)O(6) + 6O(2)
Aerobic respiration equation
glucose + oxygen —> carbon dioxide + water + energy
Anaerobic respiration (humans) equation
glucose —> lactic acid
