~1~ DishaEducentre Exhaustive Notes 5. Photosynthesis PHOTOSYNTHESIS Scope of Syllabus: The internal structure of chloroplast should be explained to give an idea of the site of light and dark reaction. Opening and closing of stomata should be explained. Teachers should stress upon the importance of a correct balanced chemical equation. The terms photochemical for light phase and biosynthetic for dark phase must be introduced. In the light reaction, activation of chlorophyll molecule followed by photolysis, release of O2, formation of ATP and NADPH should be taught. In the dark reaction, (detailed equations are not required) only combination of hydrogen released by NADP with CO2 to form glucose to be discussed. Adaptations in a plant for photosynthesis and experiments with regard to the factors essential for the process should be discussed. I. Definitions and Explanations 1. Photosynthesis 2. Chlorophyll 3. Chloroplasts 4. Photolysis 5. Phosphorylation 6. Photophosphorylation Photosynthesis is an anabolic process by which living plant cells containing chlorophyll produce food substances (glucose and starch) from carbon dioxide and water by using light energy, and releasing oxygen as a waste product. The green colouring pigment found in chloroplasts of the leaves are called as chlorophyll. Chloroplasts are microscopic oval bodies bounded by a double membrane that are present in plant cells. They contain the green pigment chlorophyll. The reaction in which water molecules splits in the influence of light, and forms hydrogen and oxygen is known as photolysis. In any reaction, if the phosphoryl group is added, it is called phosphorylation. The conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP), which occurs in the presence of light and chlorophyll, is known as photophosphorylation. It can be represented as:light , chlorophyll 7. Destarched Plant ADP ATP A plant from whose leaves starch has been removed is known as a destarched plant. This is done by keeping the plant in dark for 5-6 days. 8. 9. II. Questions-Answers 1. What is photosynthesis? Mention its raw materials and its by-products. Write the overall chemical equation involved in photosynthesis. ANSWER Photosynthesis is the process by which living plant cells containing chlorophyll produce food substances (glucose and starch) from carbon dioxide and water by using light energy, and releasing oxygen as a waste product. Raw materials: carbon dioxide, water By-products:glucose, oxygen, water, energy Notes Prepared by Neil Valentine D Silva
