Green plants, in fact, have to make or rather synthesise the food they need and all other organisms depend on them for their needs. Green plants carry out ‘photosynthesis’, a physico-chemical process by which they use light energy to drive the synthesis of organic compounds.
Major Concept. In this Unit you will learn: Ø Introduction and Role of ATP Ø Photosynthesis. Ÿ Introduction of Equation Ÿ Role of Chlorophyll and Light Ÿ Limiting Factors in Photosynthesis. Ø Respiration. Ÿ Aerobic Respiration, Anaerobic Respiration Ÿ Mechanism of Respiration (Glycolysis, Krebs Cycle, Electron Transport Chain) Major Concept.
CHAPTER 10-Photosynthesis. • Life on Earth is solar powered. • Photosynthesis nourishes almost all the living world directly or indirectly. All organisms use organic compounds for energy and for carbon skeletons. Organisms obtain organic compounds by one of two major modes: autotrophic or heterotrophic.
photosynthesis. If you carefully observe a cross-section of a leaf under the microscope (shown in Fig. 5.1), you will notice that some cells contain green dots. These green dots are cell organelles called chloroplasts which contain chlorophyll. Let us do an activity which demonstrates that chlorophyll is essential for photosynthesis. 2024-25
During the process of photosynthesis, carbon dioxide enters through the stomata, water is absorbed by the root hairs from the soil and is carried to the leaves through the xylem vessels. Chlorophyll absorbs the light energy from the sun to split water molecules into hydrogen and oxygen.
