B1.4 Photosynthesis Flashcards
Which type of organisms use photosynthesis to make their own food?
Producers
What type of reaction is photosynthesis?
Photosynthesis is an endothermic reaction
Where does photosynthesis take place?
Photosynthesis takes place in the chloroplasts
What is the word equation for photosynthesis?
Carbon dioxide + Water → Glucose + Oxygen
What is the symbol equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
What is the effect of temperature on the rate of photosynthesis?
- As temperature increases, so does the rate of photosynthesis
- Once the temperature exceeds the optimum, the rate of photosynthesis decreases as enzymes begin to denature
What is the effect of light intensity on the rate of photosynthesis?
As the light intensity increases, the rate of photosynthesis increases
What is the inverse square law?
As the distance from the light source
doubles, the light intensity quarters Light intensity ∝ 1 / distance2
What is the effect of carbon dioxide concentration on the rate of photosynthesis?
As the concentration of carbon dioxide increases the rate of photosynthesis increases
What is a limiting factor?
A factor that limits the rate of a reaction
when there is not enough of it.
