Why do sunflowers always reach towards the sun? There are two schools of thought:
- It’s due to differential growth of the stem. There’s a growth-regulator that builds up in the shaded side of the sunflower’s stem, making that side grow faster than the sunny side. This causes the stem to bend towards the sun.
- Go outside, stand on your tippy-toes, stretch your arms out wide, and feel the warmth of the sun on your face. Feels good, eh?
