Photosynthesis.

?
What is the equation for photosynthesis?
carbon dioxide + water --> glucose + oxygen.
1 of 10
What is the essential catalyst for photosynthesis?
Light.
2 of 10
Why are leaves green?
The chlorophyll in the leaves reflects green light, but absorbs the others.
3 of 10
What role does chlorophyll play in photosynthesis?
It traps the sunlight energy.
4 of 10
How can you test for photosynthesis in a land plant?
Use iodine to test for starch in the leaf.
5 of 10
Which factors limit photosynthesis?
Temperature, light intensity and concentration of carbon dioxide.
6 of 10
Why does increasing the temperature eventually halt photosynthesis?
The enzymes which make the reaction possible denature.
7 of 10
What happens to the glucose produced during photosynthesis?
It is used to respiration, or converted to fats or glucose or starch, or it is used to form cellulose.
8 of 10
What is the standard level of carbon dioxide in the atmosphere?
0.04%.
9 of 10
What are three ways of increasing the level of carbon dioxide in the atmosphere?
Propane burners, flue gases and liquid carbon dioxide.
