A scientist examined a section through a young root near its growing tip.
| Region | Observations |
|---|---|
| A | Many cells are dividing. Cells produced in this region later develop different structures. |
| B | Hollow tubes are formed from dead cells. Their walls contain lignin, and the tubes contain water and mineral ions. |
| C | Living, elongated cells are joined end to end. There are pores in the end walls, and the cells contain dissolved sugars. |
A student claims that regions B and C are the same tissue because both transport substances.
Evaluate the student's claim. Use evidence from all three regions and the organisation of the root in your answer.
