Which colors of light are most effective for photosynthesis
Different colors of light changed to see how each color effects the photosynthetic rate.
The principal colors of light used in photosynthesis.
The plant responded to the different colored light as follows: The rate of photosynthesis was the most successful in white light, and more successful in red and blue lighting, than in green and yellow lighting systems.
In addition, since the team used different lights for the different colors, the light intensity may have been unequal, also resulting in inaccurate data.
If we were to do the lab again, we would include a trials with more colors of the visible light spectrum such as orange and violet to get a more comprehensive and seamless set of data.
What Is Photosynthesis? From Light Energy to Chemical …
Light Filters are used and
light intensity stays the same The colors used in order of wavelength
blue being the smallest and red the largest so the order will go
white, blue, green, yellow, orange, red.
Our results show that different color lights definitely does have a strong direct correlation with the rate of photosynthesis/growth of a plant.
LIGHT ABSORPTION IN PHOTOSYNTHESIS
Absorption spectra showing how the different side chains in chlorophyll a and chlorophyll b result in slightly different absorptions of visible light.
photosynthesis notes - Biology Junction
If white light is a mixture of several wavelengths of colors and the chlorophyll in green leaves absorb energies from all visible light except green, then exposing white light to a green plants will result in the fastest rate of photosynthesis, followed by blue or red.
Therefor, the faster the rate of photosynthesis, the faster the leaves rises.
There are five matters that affect the rate of photosynthesis: light intensity, temperature, CO2, water, and the color of light in general.

Photosynthesis - Wikipedia
affect the rate of photosynthesis: light intensity ..
Red will have a very high photosynthetic rate
as even though it has the longest wavelength and therefore carries the
least energy it will be greatly absorbed so a lot of the light energy
will be used rater than reflected.
Photosynthesis - Part I: The Sun and Light ..
Green or yellow light will have the slowest rates of photosynthesis because they are reflected by the pigments in the plant.
DESCRIPTION & ANALYSIS
SOURCES OF ERROR AND IMPROVEMENTS
In this lab experiment, the team examines how the rate of photosynthesis is affected by different light colors in the leafs.
It actually uses only certain colors to make photosynthesis ..
Record or report findings.
Rate of photosynthesis (measured by ET50, time it took for 50% of the leaf disks to float up)
Color of light (wavelength of light)
Light intensity, temperature, bicarbonate concentration (0.2%), depth of bicarbonate solution, direction of incoming light, pH, amount of soap, size of leaf disk, type of plant
Ten trials for each color, however for each trial, a few disks did not float up.

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....
