Do plants grow differently in different colors of light?
In this experiment you will test the growth of plant seedlings under different colors of light. Within the cells of a plant’s leaves and stems, there are various pigments that react to light to perform photosynthesis. The pigments vary in color and concentration. Each pigment absorbs all colors of light except the color of the pigment itself, which is reflected. For example, if a plant contains mostly green pigments such as chlorophyll, the plant should grow well under all colors of light except green because it reflects most of the green light without absorbing it. As a result, the plant is “starved” for light and cannot perform the photosynthesis process needed to produce food and grow. To begin this experiment, use what you know about…
