- This tree is about to eat! Let's closely observe how photosynthesis is made for food.
- Carbon dioxide enters the leaf first.
- Water is absorbed into the leaf.
- Photosynthesis takes place in the chloroplast which only plant cells have. Carbon dioxide and water are both reactants required for photosynthesis to take place.
- Light hits the pigment in the membrane of a thylakoid, splitting the water into oxygen.
- Light reactions are split up into two types; there is light independent and light dependent. This step is light dependent.
- And that is the process of photosynthesis!
- The Calvin Cycle ( light independent) uses the carbon dioxide that has been collected to help produce glucose. ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) give the energy for the reactions to occur.
- Carbon Dioxide Water
- 6CO2 + 6H2O
- Solar Energy
- The End.
- Photosynthesis
- C6H12O6 + 6O2
- Glucose Oxygen
- In light dependent reactions light energy is used to convert ADP (adenosine diphosphate) to ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) to NADPH (nicotinamide adenine dinucleotide phosphate).
- The second of two major stages in photosynthesis (after the light reactions), involving CO2 fixation and reduction of the fixed carbon into carbohydrate.
