hi frnd
here is ur answer

Materials
2 1-foot tall cardboard boxes with lids
Piece of cardboard
Ruler
2 small lamps
2 full spectrum light bulbs
Box cutter knife
Masking tape
1 3” x 3” piece of clear, red, green, and blue cellophane
Water
Spray bottle
Camera
8 bean seeds
8 small pots
Procedure
First, get your plants growing. Plant two of your bean seeds in two different pots, water them, and wait for them to poke out of the ground.
While you’re waiting, get your boxes ready. Cut a hole 2” in diameter about 3 inches from the bottom of each box. Place the clear cellophane over the hole. This will let all of the light into the box. Over the hole in the other box, place the red cellophane. This will only let red light into the box.
Put one plant in the first box and one in the second. Use a ruler to position each bean plant two inches away from the cellophane window. Take a photo of the plants, looking downward from the top of the box.
Put the boxes on different sides of the same room.
Now it’s time to light things up! Put the lamps next to the boxes on the side with the cellophane window. Take out your ruler again and measure to make sure that the lamps are the same distance from the hole.
Put the lids on each box.
Every morning, turn on each lamp. Every night, turn off the lamps before you go to bed. Leave the plants to grow for a week.
After a week has passed, remove the lid and take a photo looking downward. Then remove the plants and take a photo from the front. Do the plants look different? Is one taller than the other? Is one twisted in a different direction?
Do the same experiment with new bean plants, but change the color of cellophane to blue. Finally, repeat the experiment with green cellophane.
Compare the photos of each bean plant after it had been growing for a week. Did the plants turn more toward a certain color? Was there a color they didn’t like?
Results
The control plants will do better than the plants that are only exposed to one wavelength of light. The plants will grow better in red and blue light than in green light. The plants will grow toward red and blue light but will not move toward the green light.
hope its helpful, ,,,.. and if it is helpfull then plz mark as brainliest
