8. Sunflowers: Tracking the Sun’s Path
Sunflowers are famous for their heliotropism—the ability to track the sun’s journey across the sky each day. This graceful movement from east to west is guided by internal circadian clocks that “remember” the sun’s position and anticipate its movement. By aligning their faces to the sun, sunflowers maximize photosynthesis and growth efficiency. This daily dance reveals a sophisticated internal system that combines memory, timing, and environmental awareness.
