photosynthesis:the process in which carbon dioxide and water react in the presence of sunlight and chlorophyll(present in the leaves of plants) to form glucose is called the photosynthesis.oxygen and water are released in this process as bi_products.this process takes place in plants only in daytime as it needs sunlight.reaction is as follows: 6CO2 + 12H2O-----> C6H12O6 + 6O2 + 6H2O where C6H12O6 is the glucose.
respiration:the process in which breakdown of organic material(GLUCOSE) takes place in the presence of oxygen to give carbon dioxide and water is called the respiration.energy is also released in this process.it takes place in plants both in day and at night because it doesnt need sunlight.reaction is as follows: C6H12O6 + 6O2 -----> 6CO2 + 6H2O + ENERGY .
