Here's why:
* Photosynthesis is the process where plants use sunlight, water, and carbon dioxide to create glucose (a sugar) and oxygen.
* Glucose is a type of carbohydrate that stores chemical energy within its bonds.
* Plants use this chemical energy in glucose to fuel their growth and other life processes.
So, while plants absorb light energy from the sun, they transform it into chemical energy stored in the form of glucose.
