Chapter 8: Photosynthesis Flashcards
Name the products of photosynthesis
Glucose and oxygen
Name 4 limiting factors of photosynthesis
- Amount of chlorophyll
- Temperature
- Carbon dioxide levels
- Light intensity
What is the inverse square law
1/distance(d) squared
Where in a plant does photosynthesis take place?
Palisade layer in the Chloroplasts
What is an endothermic reaction?
A reaction in which the energy enters a source from the environment
What is the word equation for photosynthesis?
(6)CO2+(6)H2O= C6H12O6+(6)O2
Why do plants store glucose as starch?
They do this as at a time where photosynthesis is unable to happen like the winter, the glucose is ready and stored for photosynthesis.
What is meant by a limiting factor in photosynthesis?
A limiting factor in photosynthesis is when something like temperature, amount of carbon dioxide or light intensity is limiting the reaction
What effect would a low carbon dioxide level have on photosynthesis?
This would slow down the rate of photosynthesis occuring
How are light intensity and the inverse square law linked?
They are linked as light intensity is equal to the distance of the light from the source squared
How could you measure the effect of light intensity on photosynthesis?
You could use a pond weed to show the amount of oxygen being produced which is the same amount of photosynthesis. You could adjust the distance of a lamp from the source and see how this effects the rate.
