Topic 8 - Photosynthesis Flashcards
What is the word equation for photosynthesis?
Carbon Dioxide + Water —> Glucose + Oxygen
What is the formula for the glucose?
C6H12O6
What is the balanced symbol equation for photosynthesis?
6CO2 + 6H2O —> C6H12O6 +6O2
Photosynthesis is what type of reaction meaning that it?
It is endothermic and thus it absorbs energy from the surroundings.
What does chlorophyll do?
Absorbs heat and light for photosynthesis and turns plants green.
In photosynthesis, _____ energy is transferred into _________ energy in glucose which is a ____________. What three words finish the sentence?
Light, chemical, carbohydrate.
When testing for photosynthesis in a plant, what material are you testing for?
Starch, energy stored from photosynthesis as a carbohydrate.
What do we use to test for starch (can be used for topic 3 too)
Iodine.
What is a limiting factor?
A limiting factor is any factor in a reaction that slows the process down.
Temperature can be a limiting factor of photosynthesis, what does it limit?
Enzyme activity.
The amount of Carbon Dioxide can be a limiting factor of photosynthesis, what does this limit?
The amount of glucose created as it is the source of carbohydrates.
The amount of light can be a limiting factor of photosynthesis, what does this limit?
The amount of energy in the reaction.
When using light intensity as a limiting factor, what is the
relationship between light intensity and distance? Give the name of the relationship and the equation.
The inverse square relationship, where light intensity = 1/distance2
Why is photosynthesis an endothermic reaction?
Light energy is required to produce glucose.
How do plants produce proteins?
Glucose is linked with nitrates absorbed with the soil.
