Photosynthesis is defined as the process by which plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This process primarily takes place in the chloroplasts of plant cells, where chlorophyll captures sunlight. During photosynthesis, carbon dioxide from the air and water from the soil are combined using this captured light energy to produce glucose and oxygen. This conversion of sunlight into chemical energy is crucial for the sustenance of plant life and serves as the foundation for the entire food web, supporting life on Earth.

Understanding photosynthesis is important for tree trimmers and those in the field of arboriculture, as it emphasizes the significance of trees in the ecosystem, showing how they produce food for themselves and oxygen for other organisms. Recognizing the role of photosynthesis can help professionals appreciate how to maintain and care for trees, ensuring they remain healthy and productive.
