B8 - Photosynthesis Flashcards
What is the word equation for photosynthesis?
-Carbon dioxide + Water –> Glucose + Oxygen
What is the balanced symbol equation?
-6CO2 + 6H2O –> C6H12O6 + 6O2
Is photosynthesis endothermic or exothermic?
-Endothermic
Where in the leaf does photosynthesis happen?
-Chloroplasts
What is the respiration word equation?
-Glucose + Oxygen –> Carbon dioxide + Water
What are limiting factors?
-Reactants which if in short supply, limit the rate of photosynthesis
How does the light intensity affect rate of photosynthesis?
-The brighter the light, the faster the rate of photosynthesis but only up to a certain point.
What is the inverse square law?
-Light intensity increases or decreases in inverse proportion to the square of the distance between the light source and the plant.
What is the equation for inverse square law?
-1/distance^2
How does temperature affect rate of photosynthesis?
-Temperature will help enzyme activity until they are denatured
How does the carbon dioxide concentration affect the rate of photosynthesis?
-The less carbon dioxide, the lower the rate of photosynthesis
How do lack of chlorophyll affect the rate of photosynthesis?
-No chlorophyll means no way the photosynthesise.
What could increase the rate of photosynthesis?
-Greenhouse conditions
In some greenhouses, the plants are grown in water. Why is that?
-It perfectly balances nutrients.
The action of growing plants in water to balance nutrients is called what?
-Hydroponics
