Detailed explanation-1: -Photosynthesis in plants makes useful organic compounds out of carbon dioxide through carbon-fixation reactions. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce oxygen and organic compounds.

Detailed explanation-2: -Photosynthesis reverses these processes by starting with inorganic carbon dioxide and transforming it into organic compounds that can be used as fuel. In this way, photosynthesis is an important part of carbon cycling, because photosynthesis has a reciprocal relationship with glycolysis and cellular respiration.

Detailed explanation-3: -Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

Detailed explanation-4: -Photosystems absorb light and use electron transport chains to convert energy into the chemical energy of ATP and NADH. The subsequent light-independent reactions then assemble carbohydrate molecules with this energy. Photosynthesis in desert plants has evolved adaptations that conserve water.
