Photosynthesis is the process of producing glucose using the raw materials water, carbon dioxide and radiant energy. Which gets trapped by the chlorophyll molecules and then oxygen is emitted as a byproduct of the process. It is the conversion of radiant energy into chemical potential energy. The occurrence of photosynthesis is very important for us humans, because it provides us with the oxygen we need to breathe and plants are at the base of every food chain and therefore without them. , Crollerei.Photosynthesis has 4 factors needed to occur: chlorophyll, water, carbon dioxide and sunlight (radiant energy), these also affect the rate of photosynthesis depending on the amount. In this investigation the (solar) light factor will be studied. We already know that light is necessary for photosynthesis to occur, but it will be demonstrated by an experiment and literature reviews that it is indeed necessary. Light is necessary for photosynthesis to occur and with greater light intensity photosynthesis will occur more. demonstrate that the above hypothesis is true by carrying out research in the form of literature reviews on the factor and photosynthesis and carrying out a survey/experiment.Literature Review1. The effect of full, 60% or 90% radiant energy with reduced intensity was studied on a certain type of grass. What was studied was the rate of photosynthesis, the growth of the plant, and some other factors. These were compared to plants grown in shade and it was concluded that plants grown in full sunlight produce more biomass, or organic matter used as fuel, stems, leaves and roots. Plants grown in 60% and 90% shade flowered... in the center of the paper... and this affected the results a bit. One recommendation is to allow more than an extra week for the experiment so that you can look for the sunniest days for the experiment in order to get the best and correct results.
