Plants prepare their food by photosynthesis. Photosynthesis, Nutrition in Plants, Class 7 - The process by which green plants make their own food from carbon dioxide and water by using sunlight energy is called photosynthesis. Equation 6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2 H 2 0 – Water. Photosynthesis is the process by which green plants, algae and some forms of bacteria use energy from sunlight to convert carbon dioxide and water into glucose. Answer: The process by which green plants make their own food from carbon dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis. Required fields are marked *.

Join now. This reaction results in the formation of 12 molecules of phosphoglyceric acid (PGA). NCERT Extra Questions for Class 10 Science Chapter 6 Life Processes with Answers will help to score more marks in your CBSE Board Exams. Class 6 Biology Getting to Know Plants. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. The … Without it there would be no green plants, and without green plants there would be no animals. Because PGA is a three-carbon compound and is the first stable product of the process, hence dark reaction is also called the cycle.
