The following is the difference between the transport of materials by xylem and phloem :
| Transport by Xylem |
Transport by Phloem |
The xylem carries water and soluble salts to the trunk, branches, and leaves of the tree. |
The food substances are transported from the leaves to other parts of the plant in a dissolved state. |
The rise of water and dissolved salts is due to the pull caused by evaporation. |
This increases the osmotic pressure, which transports substances from the phloem to the tissues and the pressure decreases. |
| It does not consume energy. |
It requires energy because it is an active process. |
