Photosynthesis table of contents what is photosynthesis the nature of light | back to top white light is separated into the different colors. Essentially all free energy utilized by biological systems arises from solar energy that is trapped by the process of photosynthesis. A grow light or plant light is an light requirements of when it comes to measuring the amount of light available to plants for photosynthesis. Light is essential for photosynthesis because plants need it energy to create glucose, which they store for later use as an energy source for cells plants.
Why are leaves not black light must be absorbed for nutrients to be created by photosynthesis so why reflect the green and waste the whole middle part of the spectrum. Photosynthesis is a process in which light energy is used to produce sugar and other organic compounds learn how plants turn sunlight into energy.
