After a period of frost, scientists found that cells at the growing tip of the main shoot were damaged in some seedlings. Cells in the roots were not damaged.
The scientists measured the seedlings immediately after the frost and 10 days later.
| Seedlings | Mean shoot length immediately after frost in mm | Mean shoot length after 10 days in mm | Mean root length immediately after frost in mm | Mean root length after 10 days in mm |
|---|---|---|---|---|
| No damage | 38 | 63 | 22 | 39 |
| Shoot tip damaged | 39 | 40 | 23 | 40 |
Explain how the damage caused the pattern of growth shown in the table.
