Photosynthesis The process of photosynthesis takes place inside the chloroplasts, which are organelles found within plant cells. The production of glucose, sometimes known as sugar, is an end product of the process of photosynthesis, which takes place in the chloroplasts of plants. The chloroplasts are responsible for the initial phase of photosynthesis, which is the absorption of sunlight. The production of glucose from carbon dioxide and water is the second phase in the process of photosynthesis. The mechanism in question is known as carbon fixation. The generation of oxygen gas from water is the third and last phase in the process of photosynthesis. The term for this kind of reaction is photolysis. Plants manufacture glucose, sometimes known as sugar, via a process called photosynthesis, which takes place when sunlight is present.
