Activity 6.2 — Phototropism in Plants
NCERT Activity 6.2: Place a potted plant near a window and observe how the stem bends toward light (phototropism) and roots grow away.
How To Perform
1
Place Plant Near Light
Position the potted plant near a window so light comes from one side.
2
Observe Auxin Redistribution
See how auxin moves to the dark side of the stem when light shines from one direction.
3
Watch Stem Bend
The stem bends toward light as cells on the dark side elongate more.
4
Root Response
Roots grow away from light — negative phototropism.
5
Classify the Response
Understand the mechanism of phototropism and auxin's role.
⚠️ Safety Notes
- •Ensure the light source is not too hot to avoid damaging the plant.
- •Use a healthy, growing plant for best results.
- •Allow the plant to respond for a few hours in a real experiment.
