Plant Growth Under Different Colors Of Light
Camila Farah
I ve chosen to let garden cress grow underneath various colors of light.
Plants get their energy from light but different colors of light have different energy levels. The results of the plant under orange light will be between green and blue light. Blue light is essential at the beginning of a plant s growth cycle as this is the type of light that plants first absorb to help with chlorophyll production. Red light impacts plant growth in several ways including during the blooming and flowering phase.
White red green blue. This process is called photomorphogenesis. My hypothesis is correct. Overall blue light has an influence over multiple functions in a plant s life and is a crucial color to have in your own grow room or grow box in order to ensure the most optimal growth.
Plants with blue light grew on average tallest followed by red and lastly by green. A crucial component to plant growth is sunlight which energy that allows a plant to go through photosynthesis and produce glucose. Sunlight contains all of the colors of the visible. This video is part of a biology project of mine.

It was thought that the green light would cause the plant to grow faster since it is a green plant. Blue light also has an effect on photosynthesis and more exposure to this light can increase a plant s growth and maturity rates. The color lights used were green red blue and white. Blue light for example helps encourage vegetative leaf growth.
The plants were watered and measured daily before the lights were turned out. For one week the plants were put under their assigned light color for 12 hours and spent 12 hours in darkness.
