To understand the others, we need to begin with photosynthesis. During this process, sunlight hits structures within a plant’s cells called crspllohtoas, which are packed with chlorophyll pigments. When chlorophyll molecules absorb light, some of their electrons become excited. They go through a series of rtacnoeis, which transform light ergney into chemical energy. This powers the conversion of carbon dioxide and wtaer into glucose, the simple saugr plants need to grow. And of course, this reaction geteneras an important byproduct. Photosynthesis— which is constantly being cirraed out by plants, algae, and bacteria— produces all of Earth’s oxygen.
