Photosynthesis is the process by which green plants prepare food. The process is done in the presence of sunlight.

We always want to know ‘Is photosynthesis exothermic or endothermic’. today we will find the answer.

Before we dip into the topic, we must know what is an exothermic reaction and endothermic reaction?


Exothermic reaction

The reaction in which heat is liberated.

Endothermic reaction

The reaction in which heat is absorbed.

What is photosynthesis?

Photosynthesis is the process in which food is prepared by green plants, actually, this process involves the conversion of light energy into chemical energy.

Photosynthesis is done by green plants, algae, and some bacteria.

Essential components of photosynthesis

1 Carbon dioxide

2. Water

3. Sunlight

4. Chlorophyll

Photosynthesis equation

`6CO_2 + 6H_2O \overset{sunlight}\underset{cholrophyll}{\rightarrow} C_6H_12O_6 +6O_2`

Photosynthesis is an endothermic process because it needs energy to convert carbon dioxide and water into glucose (carbohydrates).

Photosynthesis is done in the presence of chloroplast (green pigment – chlorophyll)found in the leaves of green plants in the presence of sunlight.

Green plants absorb sunlight and light energy is converted into chemical energy stored in glucose.

So, photosynthesis is an endothermic process
