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 + 6H20 -> C6H12O6 + 6O2
What is the effect of temperatures on the rate of photosynthesis?
As the temperature increases, so does the rate of photosynthesis
Once the temperature exceeds 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 intesity ~ 1/distance 2
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
