PHOTOSYNTHESIS: THE BASICS

摘要

Photosynthesis is the process by which plants, algae and some bacteria Convert carbon dioxide and water into carbohydrates using energy from sunlight. In most cases, they achieve this by splitting apart the hydrogen and oxygen in water (H2O), giving off oxygen (O2) as a by-product. In many ways, photosynthesis is the reverse of respiration: when we animals respire, we use O2 to burn up carbohydrates, releasing CO2 and producing the energy we need to live.
