Effect of colour of light on the rate of photosynthesis
Follow the guidelines in the Universal Rubric and the Lab Report Grading Template
Rubric on Laulima.
Your report must consider/ include all the colors of light that were measured, and the
absorption data of the chlorophyll extracted from the Elodea, even if you didn’t do the
effect of light intensity on photosynthesis experiment
Glucose may be oxidized completely if sufficient
oxygen is available, illustrated by the following equation:
C6H12O6 + 6 O2 ⟶6 H2O + 6 CO2 + energy
The rate of photosynthesis is affected by numerous factors including the amount
and the wavelength of light available.
Energy is inversely proportional to wavelength,
so that long wavelengths, such as radio waves carry less energy than short
wavelengths such as gamma rays.

Why do you think the color of light has an influence on the rates that you measured?

Cellular Respiration and Photosynthesis
(Boundary: The fact that plants capture energy from sunlight is introduced at this grade level, but details of photosynthesis are not.) It is important to be able to concentrate energy so that it is available for use where and when it is needed.

When you are done with your readings dispose of the EtOH and the pigment extract in the
“waste ethanol” container.

You will either measure the respiration/ photosynthesis rate of Elodea under two of
five colors of lights (blue, green, orange, red, and white) (Parts A & B); or, you will record the
absorption spectrum for Elodea (Parts C & D), and measure the respiration/ photosynthesis rate
of Elodea under one of five colors of lights (blue, green, orange, red, and white) (Parts A & B).
Each color of light (blue, green, orange, red, and white) represents one treatment.
