Photosynthesis and Respiration Photosynthesis is the process by which cells use the energy of light to convert carbon dioxide and water into sugar. Photosynthesis provides the basic energy source for nearly all living things. Plants use the glucose produced to build leaves, flowers, fruits and seeds. Photosynthesis is broken down into two separate stages, the light-dependant reactions and light-independent reactions. In the light-dependant reaction, the chloroplast traps light energy from the sun and it is …

…only occur in light while respiration can occur at any time. The input of photosynthesis is carbon dioxide and water and the output is reduced carbon compounds, oxygen, and water. The input of respiration is reduced carbon compounds and oxygen, and the output is carbon dioxide and water. In photosynthesis energy is stored, and in respiration energy is used. The product of photosynthesis is glucose, and the product of respiration is CO2 and H2O.
