WHAT IS PHOTOSYNTHESIS : Photosynthesis is the process by which green plants synthesis organic food as carbohydrates in the presence of SUNLIGHT , WATER , CHLOROPHYLL , CO2 and other raw materials . Photosynthesis is a bio-chemical process by which green plants, in presence of sun light and chlorophyll with the help of Carbon Dioxide and water, manufacture carbohydrate as a main product and oxygen as a by-product. It involves a chemical reaction where water, carbon dioxide, chlorophyll, and solar energy are utilized as raw materials (inputs) to produce glucose, oxygen, and water (outputs). Chlorophyll is the main light-absorbing pigment in photosynthesis. Photosynthesis takes place mainly in the leaves of green plants and also in the stems of herbaceous plants as they also contain chlorophyll. 3. 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. The easiest way to measure the rate of photosynthesis is to quantify the carbon dioxide or oxygen levels using a data logger. Now that we know what the photosynthesis equation is, let’s break down each piece of the photosynthesis formula. Photosynthesis is the process in which green plants use sunlight to make their own food. The rate of photosynthesis can also be measured by determining the increase in the plant’s biomass (weight). Although all the above factors together interact to affect the rate of photosynthesis, each of them individually is also capable of directly influencing the process without the other factors and thus called limiting factors.
