Definition of photosynthesis
Table of Contents
Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight into chemical energy stored in glucose or other sugars. It takes place in chloroplasts, where pigments like chlorophyll absorb light energy and convert it into chemical energy through a series of complex reactions. Carbon dioxide from the air and water from the soil are utilized in this process, with oxygen released as a byproduct. Essentially, photosynthesis is the fundamental mechanism that sustains life on Earth by providing plants with the energy they need for growth and maintenance.
