Photosynthesis (Equation) Flashcards
What is the reaction that plants use to trap energy?
Photosynthesis
Because photosynthesis takes in energy, it’s an…
Endothermic reaction
Leaves contain the green chlorophyll, what does this absorb?
Light energy
What is the equation for photosynthesis?
. Light
Carbon + Water —————> Glucose + Oxygen
Dioxide Chlorophyll
What is the equation in symbol form?
CO2 + H2O ————-> C6H1206 +O2
Why does the rate of photosynthesis drop when light intensity does?
Photosynthesis needs light to carry out, so when there is no light, photosynthesis can’t take place
Why does the rate of photosynthesis increase when light intensity does?
The more light available to the plant, the faster photosynthesis will be able to take place
If we increase the light intensity and photosynthesis also increases, that tells us that the light is…
A limiting factor– photosynthesis was not as fast as it could’ve been because there wasn’t enough light
If we keep increasing the light intensity, there comes a point when photosynthesis…
No longer increases– light intensity is not a limiting factor anymore and something else is in short supply, like CO2 in the air
As we increase the CO2 levels, the rate of photosynthesis…
Increases—CO2 is a limiting factor
When the rate of photosynthesis stops increasing…
CO2 is no longer a limiting factor
Because leave with less chlorophyll can’t absorb as much light, this will…
Lower the rate of the photosynthesis
As we increase the temperature, the enzymes involved in photosynthesis work faster so the rate…
Increases
If we keep increasing the temperature, the enzymes will denature and the rate of photosynthesis…
falls
