Photosynthesis is a light-dependent and endothermic reaction.
Photosynthesis is an endothermic reaction.
Photosynthesis is an endothermic reaction.
To determine the type of reaction that is photosynthesis, we first need to understand the different types of reactions. There are two main categories of reactions: endothermic and exothermic.
An endothermic reaction absorbs energy from its surroundings in order to proceed. In the case of photosynthesis, energy in the form of sunlight is absorbed by chlorophyll molecules in plant cells to drive the reaction.
On the other hand, an exothermic reaction releases energy into its surroundings. Examples of exothermic reactions include combustion, where fuel burns and releases heat and light energy.
In the case of photosynthesis, it is the conversion of light energy into chemical energy in the form of glucose and oxygen. This process requires the absorption of light energy, making it an endothermic reaction.
Therefore, the correct response is: endothermic.
