Xylem vessels and phloem tubes are gathered together into collections called vascular bundles. They are found in different regions of the leaf, stem and root.

Xylem vessels and phloem tubes are different in structure and do different jobs:
| Xylem | Phloem |
|
Carries water and minerals from roots to the leaves |
Carries dissolved food substances both up and down the plant |
|
The movement of water up the plant and out of the leaves is called transpiration |
The movement of the dissolved food is called translocation
|
|
Made of vessels which are hollow tubes made of thickened dead cells |
Made of columns of living cells |
Remember phloem for food and xylem for water.
