Photosynthesis

    The term photosynthesis has a connotation of meaning "putting together with light". The actual definition of photosynthesis is the process through which light energy, water, and carbon dioxide are converted to carbohydrates and oxygen in the presence of chlorophyll. Chemically expressed:
H₂0 + CO₂ + light energy ------>C₃H₆O₃ + O₂
Photosynthesis is necessary to produce the carbohydrate which can be stored or used in cellular respiration.
