In our wheat fields, phototropism is when the young shoots lean towards the morning sun, and gravitropism is how the roots know to go down, no matter how the seed falls. But I'll tell you, the book answer is too simple. From my tractor, I see our modern wheat varieties don't bend to the sun so strongly—they stand more upright, by design, so we can plant them closer together. Life isn't about a single sun or gravity; it's about breeding a plant that fits the field and the farmer's heart.
