It is not just important for plants, which depend on it for their food, but is equally important for humans. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. This whole process of making food by plants is called photosynthesis. Various factors influence/affect the photosynthesis process. vanessa on March 07, 2011: these diagrams were very helpful for my assingment of drawing a diagram to explain photosynthesis that a young child would understand, thankyou!! Chlorophyll is necessary for photosynthesis; hence photosynthesis takes place only in green plants. Factors Affecting Photosynthesis. CBSE Class 10 Science Practical Skills – Light is Necessary for Photosynthesis. Roots aren't exposed to light, so there's no point for a plant to put chlorophyll in them. Photosynthesis is the primary source of energy in autotrophs where they make their food by utilizing carbon dioxide, sunlight, and photosynthetic pigments. Answer: Glucose and oxygen are the final products after photosynthesis. It is the only known method by which oxygen is added to the atmosphere to compensate for oxygen being used in the respiration of organisms and burning of organic fuels. Important Science Diagrams From All Chapters For CBSE Class 7 Answer: Water is transported to the leaves through pipe like structures from the roots of plant. Photosynthesis helps to maintain a balance between oxygen and carbon dioxide in the atmosphere as it absorbs carbon dioxide and release oxygen. Question 9: What is the ultimate source of energy?
