1

Define photsynthesis.

The production of carbon compounds in cells using light energy.

2

Distinguish between the action and absorption spectra for photosynthesis.

Action: the rate of photosynthesis at each wavelength
Absorption: The percentage of light absorbed at each wavelength

3

Where does all of the oxygen come from in photsynthesis? Write the equation of the reaction.

Photolysis of H2O: 2H2O --> 4e- + 4H+ + O2

4

Write a word equation for the process of photosynthesis.

carbon dioxide + water --> carbohydrate + oxygen

5

What is the granum of the chloroplast?

Structure containing carotenoids and chlorophyll; site of photosynthesis

6

What are thylakoid membranes?

site of light-dependent reactions

7

What is the stroma?

Where CO2 converted into sugar

8

What is the lumen of the chloroplast?

It is the thylakoid space. Where molecular oxygen is produced from water. Where photosynthesis takes place.
