What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During cellular respiration? In Photosynthesis light energy along with carbon dioxide are used to make molecules
Premium Oxygen Cellular respiration Adenosine triphosphate
Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Photosynthesis summary Photosynthesis [photosynthesis: The chemical change
Premium Photosynthesis Oxygen Plant
Photosynthesis is a process through which plants and some certain types of bacteria get energy from the sun’s UV-rays and use it to create and store sugar that is transformed into ATP by cellular respiration later on in the process. In plants‚ this process takes place in chloroplasts‚ which concentrate in the mesophyll cells‚ with the help of chlorophyll‚ the green pigment‚ which is directly involved in photosynthesis. It is important to understand that we see leaves green simply because the green

Materials: * 600mL beaker * Access to water * Safety glasses * Bunsen burner * Tripod * Gauze mat * A large white evaporating dish * Scissors and forceps | * Glass stirring rod * Test tube rack * Test-tube (30mm x 180mm) * Methylated spirits * Iodine solution * 100mL
Premium Photosynthesis Water Leaf
Photosynthesis The leaves are the part of a plant where most photosynthesis takes place. If you cut a leaf in half and look at the cut end‚ it would look like this: Key: 1. Waxy cuticle: this gives the leaf a waterproof layer‚ which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of damp‚ loosely packed cells. 5. Lower epidermis: layer of cells on the lower surface. 6. Air
