|It is an anabolic process in which simple inorganic substances react to synthesize complex organic food.
|It is a catabolic process in which complex organic foods are oxidized or broken down into simpler inorganic forms.
|Carbon dioxide is absorbed.
|Carbon dioxide is released.
|Oxygen is evolved.
|Oxygen is absorbed or used.
|It occurs in the presence of light.
|Light is not essential for this process as it occurs day and night.
|It occurs only in green plants. i.e. presence of chlorophyll is necessary for this process.
|It takes place in all plants and animals. The presence of chlorophyll is not necessary.
|Carbon dioxide and water are used as raw materials.
|Glucose and oxygen are used as raw materials.
|It is an endothermic process as energy is stored during this process.
|It is an exothermic process, because energy is released during this process.
|In this process, food is accumulated and dry weight of the plant is increased.
|Weight of the plant is decreased due to the oxidation of food.
|It occurs in chloroplast.
|It occurs in mitochondria.
|The end products are glucose and oxygen.
|The end products are carbon dioxide and water.
|In this process, radiant energy (light energy) is converted into chemical or potential energy.
|In this process, chemical or potential energy is converted into other forms like muscular energy, kinetic energy etc.
|During this process, one glucose molecule is synthesized and 18 ATP molecules are utilized.
|During this process, one glucose molecule is oxidized and 38 ATP molecules are formed.
