Plant growth with different colored Lights. The purpose of this experiment is to find out if plants grow better a certain color light. It was thought that the green light would cause the plant to grow faster since it is a green plant. ... There was a tie between the plant under the blue and white light.
1. Make a hypothesis about which color in the visible spectrum causes the most plant growth and which color in the visible spectrum causes the least plant growth? If red and blue are absorbed more by the plant then red and blue will be the most effective and green will cause the least plant growth.
Plants use the food they make for growth and for other life processes. Sunlight is the natural energy source for photosynthesis. White light from the sun is a mixture of all the colors of the visible spectrum: red, orange, yellow, green, blue, indigo, violet.
False in a sense because it is not random. It is just that some organisms have more advantageous characteristics than others. These genes are then passed on which makes the likelihood of the next generation surviving greater.
Answer:
D. carbon dioxide
Explanation:
An increase of a plant's biomass is the result of photosynthesis. Therefore, carbon dioxide and water ultimately contribute to the huge increase in the pine tree's biomass.
