Book 29, Question 42
How can corn grow so tall so fast?
Corn is a grass that grows quickly in warm weather, shooting up several inches in a single day during the best days of summer.
It uses a special form of photosynthesis that works well in heat and bright light. Many cornfields grow taller than a grown-up. Gardeners plant corn in blocks so that wind can carry pollen from the tassels to the silks.
