For an organism to utilize light energy, it has to be absorbed. In living systems, pigments absorb light energy. Some pigments, such as melanin, absorb all wavelengths of light, and they appear black. At the other end of the spectrum, many pigments absorb only certain wavelengths of light …

The Best Plant Light Spectrum for Growing Flowering Plants | Hom…
The one with the biggest growth was plant under the red light, followed by a tie between the white light and blue light and last was the plant under the green light. CONCLUSION: The purpose of this experiment was to determine which color light the plant would grow best under. The hypothesis was that if a plant grew under a green light, then it ...

You will calculate the plant growth by measuring the height of each plant under different colors of light. You will compare these measurements and interpret a graph to determine which colors of the spectrum cause the most plant growth. Directions: Make a hypothesis (prediction) about what part of the light spectrum will cause the most plant ...

Aug 14, 2014 · Plants use the food they make for growth and for carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light from the sun in a mixture of all colors of the light spectrum: red, orange, yellow, green, blue, and violet. Light can be either absorbed or reflected by substances called pigments.
