Photosynthesis is a process in which energy is produced in the plants with the help of sunlight. In photosynthesis, carbondioxide react with water forming oxygen and food material in the form of glucose. It occurs only in plants.
Respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules with the help of oxygen produces water, carbondioxide and energy in the form of Adenine tri phosphate (ATP). It occurs in all living organisms.
