The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide. PHOTOSYNTHESIS. • Occurs in plants, algae and some prokaryotes • Anabolic (small molecules combined) • Endergonic (stores energy) • Stored as carbohydrate in their bodies. It allows the plants to absorb the energy coming from the sunlight, which is essential for photosynthesis. make their own food using light Called photosynthetic autotrophs. Photolysis Photophosphorylation It is a process of splitting of water molecule into 2H+ + 4e- + 1/2 O2 in the … These are light-dependent reactions and light-independent reactions or dark reactions. The required amount of CO2 is 300-400 PPM. Hindi Science. This process also results in the release of oxygen into the air. Photosynthesis is one of the most crucial life processes on the Earth. In photosynthesis solar energy (sunlight) is converted to chemical energy and is stored in plants as starch. (1). It helps in the survival of the plants, the creation of products essential for the survival of living beings, and also to maintain the environmental balance. The chloroplast is found only in plant cells and is essential for photosynthesis reaction. Pathway. of all life on earth relies on photosynthesis for their energy. photosynthesis. Name: Class: Photosynthesis and Respiration What is the relationship between photosynthesis and cellular As in the chemical reaction of 6CO2 + 6H2O + light C6H12O6 + 6O2. They are called anoxygenic photosynthetic bacteria, and those who do it are called oxygenic photosynthetic bacteria. 3. There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. Live. This sugar is the source of food used by most plants and ultimately, by all other consumers. It is not dependent on light and takes place in chloroplast where the products from the earlier step are used. The C 3 plants use the C 3 pathway or the Calvin cycle for the dark reaction of photosynthesis. 4.
