What is the source of glucose for living things? It is made by plants and certain other organisms. The process in which glucose is made using energy in light is photosynthesis. This process requires carbon dioxide and water. It produces oxygen in addition to glucose. Photosynthesis consists of many chemical reactions. Overall, the reactions of photosynthesis can be summed up by this chemical equation: 6CO2 + 6H2 O + light energy ! C6 H12 O6 + 6O2 In words, this means that six molecules of carbon dioxide (CO2 ) combine with six molecules of water (H2 O) in the presence of light energy. This produces one molecule of glucose (C6 H12 O6 ) and six molecules of oxygen (O2 ).

Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
Cell walls: provide structural and mechanical support, protect cells against pathogens, maintain and determine cell shape, control the rate and direction of growth and generally provide form to the plant. Cytoplasm: provides the platform for most chemical processes, controlled by enzymes.
Cell membrane: acts as a barrier, controlling the movement of substances into and out of the cell.Chloroplasts: As described above, simply contain chlorophyll, a green substance which absorbs light energy for photosynthesis.
How many components are needed for photosynthesis to occur?
The light dependent reaction requires light energy from the Sun which is composed of a range of wavelengths (colours). During the process light energy is converted into chemical energy by forming the energy-carrying molecule ATP and and the hygrogen-carrying molecule NADPH.
Where does photosynthesis occur in plant? | Biology - …
This diagram depicts photosynthesis. Photosynthesis is the process in which plants synthesize glucose. The process uses carbon dioxide and water and also produces oxygen. The plant gets energy from sunlight using a green pigment called chlorophyll. Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose is used for energy by the cells of almost all living things. Plants make their own glucose.
Where does photosynthesis occur in plant
This diagram shows the process of photosynthesis, the process of how plants convert sunlight into energy. The plant uses sunlight and water to make glucose and creates oxygen as a waste product. Chemical energy is stored in the bonds of glucose molecules.
