A student kept equal-sized samples of root storage tissue in the same external solution for 30 minutes.
| Sample | Carbohydrate stored | Mass at start / g | Mass after 30 minutes / g |
|---|---|---|---|
| A | glucose | 12.0 | 13.2 |
| B | starch | 12.0 | 12.1 |
Use the results in the table to explain why storing carbohydrate as starch would benefit the plant.
