How does a plant grow towards a light source?
What will be an ideal response?
Auxin in the tip of the shoot causes the pH inside these cells to drop, and this acidic condition causes an enzyme to become active, which weakens the cellulose in the cell wall. This causes the walls to stretch and the cell elongates. This stretching and lengthening causes a shoot to grow towards light, even if it doesn't mean growing straight up.
