Effect of light color on plants

Without this process, life would almost cease to exist. Photosynthesis by plants and algae provides us with food, fuel, and chemicals. This process also helps to maintain the O2: CO2 balance in the atmosphere surrounding us Rao,

Effect of light color on plants

One lamp with a normal light bulb One lamp with a green light bulb One lamp with a red light bulb Notebooks Optional: Camera to record progress Procedure: Take the three flower pots and add the soil.

Photosynthesis Virtual Lab

Insert one plant into each flower pot and cover it well with the soil. Water the plants, as plants need water to survive. Set the plants far enough apart that they cannot share the same light source.

Effect of light color on plants

Give each plant a letter. Plant A will be the plant that gets a regular light bulb. Plant B will get a green light bulb. Plant C will get a red light bulb.

Establish a journal or notebook to record the progress of your science project. Create a hypothesis about what you think will happen to each plant and why, and record it in your notebook. Also record the process you are going to use to find a conclusion. Set the lamps over each plant and keep them lit all day, but turn them off at the end of the school day, if this is a classroom project, or at the end of the evening, if this is a science fair project.

Make sure the plants all receive equal exposure to light and dark. The records should include pictures as well as descriptions. You should update your journal every couple of days in order to document a clear progression.

Continue the process for a week or two. Documenting and Presenting the Results What happened to each of the three plants?

Write the conclusion to this project in your notebook. Share why your hypothesis was correct or incorrect. You can now use the contents of your journal to set up a display board or other form of presentation for your science fair, or as the oral presentation component of a classroom project.Plant physiological reactions to green light and the effects of green light on plant growth have been investigated, but there is no report of plants being cultivated under green light only.

Hence, the question arises whether the plants could be grown under green light only. Plants can be grown under artificial lights, but these lights are just mimicking the effects of sunlight. Dependent on the type of plant and its natural habitat, the amount of sunlight required for healthy growth will vary, but no plant will survive for long in the absence of light.

Effect of Different Colored Lights on Photosynthesis. Anastasia Rodionova, Cassidy Davis, Sara Cucciniello. CU Boulder, Fall Our experiment tested which color (red, blue, green) would influence the plant to produce the most amount of photosynthesis.

- Read the summary in the side bar which explains how colors of light affect plant growth. - Read the procedure. Many of your tasks will be recorded in the journal which you will print out to turn in - there are 5 questions to answer in the journal, use complete, thoughtful sentences for each of these questions.

In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light. Different Colors, Different Growth Benefits Though green light has the least benefit to plants, red and blue light can have different but complementary effects on plant growth.

that white light is a mixture of all the colors in the visible spectra. In the thylakoid membranes of plants the light absorbing molecules called pigments absorb and or reflect wavelengths of light.
