photosynthesis is created by leaves and sunlight it is what creates the food for the plant
Energy from the sun is what allows plants to make their own energy through photosynthesis.
The main function of plant cells is to carry out photosynthesis, which is the process by which they convert sunlight into energy in the form of glucose. Additionally, plant cells also provide structure and support to the plant, store nutrients and water, and facilitate reproduction through processes like cell division and fertilization.
