What Is The Role Of Light In Photosynthesis
The reduction of carbon dioxide co 2 by these hydrogen atoms to form organic molecules.
What is the role of light in photosynthesis. Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide co 2 which is reduced to organic products. Plants convert water and carbon dioxide into energy required for carrying normal functions in the presence of sunlight through a process called photosynthesis. Light is the major factor for photosynthesis to take place and by doing this experiment we need to prove that light is necessary for photosynthesis. The role of light the heart of photosynthesis as it occurs in most autotrophs consists of two key processes.
Photosynthesis is a process by which phototrophs convert light energy into chemical energy which is later used to fuel cellular activities. Read more about the best led light for 4 4 grow tent. Converts light energy into chemical potential energy to provide the organism with a source of food. This occurs in the plant s thylakoid membrane in which light energy is turned into chemical energy.
In plant photosynthesis the energy of light is used to drive the oxidation of water h 2 o producing oxygen gas o 2 hydrogen ions h and electrons. The role of light energy within photosynthesis helps out during the light dependent reactions that occur in the thylakoids membranes of the. Chlorophyll beta carotene and other pigments group together in the membrane and absorb different colors of light. The chemical energy is stored in the form of sugars which are created from water and carbon dioxide.

The photosyntheticaliy active spectrum of light is between 400 700 nm. Light supplies the energy for the process and varies in intensity quality and duration. Light plays a key role in the light stage of photosynthesis wherein the plant absorbs light energy and triggers electron transfers. Light energy is absorbed by chlorophyll a photosynthetic pigment of the plant while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
