What is Photosynthesis
The Process of Photosynthesis <p>Photosynthesis takes place in the leaves of plants only. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color. Chlorophyll absorbs the sun’s energy. It is this energy that is used to split water molecules into hydrogen and oxygen.Oxygen is released from the leaves into the atmosphere. Hydrogen and carbon dioxide are used to form glucose or food for plants. Some of the glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants. Here is the process in greater detail: Photosynthesis occurs in two stages commonly known as Light dependent Reactions and the Calvin Cycle.Light dependent Reactions Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy.k Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photo
<p>systems responsible for photosynthesis.
Water is used to provide electrons and hydrogen ions but also produces oxygen. Do you remember what happens to the oxygen? The electrons and hydrogen ions are used to create ATP and NADPH. ATP is an energy storage molecule. NADPH is an electron carrier/donor molecule. Both ATP and NADPH will be used in the next stage of photosynthesis.Details about the flow of electrons through Photosystem II, b6-f complex, Photosystem I and NADP reductase have not been included here but can be found under The Process of Photosynthesis in Plants.
