Why do plants bend toward windows?
Show answer & explanation
Answer: Phototropism makes stems grow toward light
Phototropism makes stems grow toward light ✓ — Correct! Indoor plants bend toward windows because of phototropism. Light from one direction causes auxin (a growth hormone) to gather on the shaded side, where cells elongate faster and bend the stem toward the light for better photosynthesis. Rotating the plant now and then keeps growth even.
Plants like the view outside the window — Wrong. Plants don't see or prefer a view. They bend because light from one side triggers a growth response, not because they enjoy the scenery.
Windows provide warmth that pulls the plant — Wrong. Plants don't bend toward warmth; they respond to the direction of light. The warmth from a window is not what steers the stem.
