Reference no: EM1389783

A) Abstract: (In 250 words)

B) Introduction: (Briefly describle the reaction in the light and dark reactions, what is the summary equation? What are the functions of each set of reactions? Set-up the equation: What did you expect to learn from following procedures)

C) Discussion: (Discuss what the data mean about each stages of photosynthesis , Concisely state the generak cinclusions from you work)

Chart:

Chloroplasts	0.1 M PO₄ Buffer (ph 6.5)	H₂0	0.2 mM DCPIP
0.5mL	3mL	1.5mL	0
0.5mL	3mL	0.5mL	1mL
0	3mL	1.0mL	1mL
0.5mL	3mL	0.5mL	1ml

There was a limited amounts of materials used in this lab they include: four test tubes what were labeled one-four, 1.5mL of chloroplast, 12.0mL of 1.0M PO₄ which was used as a buffer at a pH 6.5, 3.5mL of distilled water, 3mL of 0.2 mM DCPIP. A 10mL graduated cylinder was used to measure the output of each solution, test tube rack and a light bulb was also used.

Test tubes were prepared according to table 13.2 and contents were mix toughly. Test tubes one-three were placed in font of light bulb and the forth was wrapped with aluminum foil and placed next to the other three tubes. And the description of the color changes were recorded.

Results

Tube #
1	Color remains clear
2	Color changes from blue to clear
3	Color remains Blue
4	Color remains Blue
