A plant shoot is grown in a cabinet with light entering from the left. After a period of growth, the increase in length is measured on the two sides of the shoot.
| Side of shoot | Increase in length (mm) |
|---|---|
| Lit side | 4 |
| Shaded side | 8 |
Explain the results in the table and explain which side of the shoot will grow faster if the light is moved to the right side of the cabinet. Use auxin in your answer.
