Photosynthesis

Paper Summary:

The paper examines the absorption spectrum of a chloroplast suspension. The paper further examines the determination of the effect of light quality (wavelength) on photosynthetic rate. The paper explores how to measure photosynthetic rate with dichlorophenolindophenol (DCPIP), determining the extent of color loss of the dye DCPIP.

From the Paper:

"The second experiment of this lab is determination of the effect of light quality on photosynthetic rate. The cabbage has the highest photosynthetic rate, xxxx(nm) in blue light. But the spinach has the highest photosynthetic rate, xxxxx(nm), in green light. Red cabbage and spinach have different photosynthetic rates in four different kinds of light, because red cabbage and spinach have different-colored leaves. For red cabbage, the highest to lowest photosynthetic rate is blue (xxxxx nm), broad spectrum (xxxxx nm), red (xxxxxnm), and green (xxxx nm)."
