This statement is false. While it is true that photosynthesis primarily occurs in plants, it does not mean that only plants can perform this process. Photosynthesis also occurs in some types of algae and certain bacteria. These organisms use sunlight, carbon dioxide, and water to produce glucose and oxygen, similar to plants.
On the other hand, cellular respiration is not exclusive to animals. In fact, all living organisms, including plants, fungi, and bacteria, perform cellular respiration. This process involves breaking down glucose to produce energy, carbon dioxide, and water. For plants, cellular respiration occurs continuously, even during the night when photosynthesis is not happening.
In summary, both processes are vital to the energy cycle on Earth and are not limited to just plants or animals.
