Photosynthesis is a light-dependent, temperature-independent, and endothermic reaction.
Photosynthesis is a light-dependent and endothermic reaction.
To determine the answer, we need to understand the process of photosynthesis. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, which is stored in the form of glucose and other organic molecules. This process involves several steps, including the capture of light energy, the conversion of carbon dioxide and water into glucose, and the release of oxygen as a byproduct.
Now let's consider the given options:
1. Temperature-independent: This refers to a reaction that is not affected by temperature. However, photosynthesis is affected by the intensity and quality of light, which makes it temperature-dependent. Therefore, this option is not correct.
2. Light-independent: This option is incorrect because photosynthesis is not a light-independent reaction. It actually depends on light energy for the process to occur.
3. Exothermic: An exothermic reaction is a reaction that releases heat energy. In the case of photosynthesis, it is not correct because it requires energy input from sunlight rather than releasing heat.
4. Endothermic: An endothermic reaction is a reaction that absorbs heat energy from its surroundings. This is the correct answer for photosynthesis because it requires the absorption of energy from sunlight to drive the process.
So, the correct answer is: photosynthesis is an endothermic reaction.
