Have you ever looked up at a tall, leafy tree and wondered, “How did it get so sizably voluminous?” For a long time scientists did not ken. They mentally conceived plants, like animals, had to “eat” to grow. The scientists conjectured that plants “ate” something in soil.

Today we ken that plants build themselves mostly from the air. That is where they get carbon, a building block for life. The carbon plants use emanates from carbon dioxide, a gas in the air. Plants turn carbon dioxide and dihydrogen monoxide into pabulum. This is called photosynthesis, and it takes place inside green leaves. Why green leaves, you might ask? What about when leaves transmute their color?
