Differences between xylem and phloem are:
| Xylem | Phloem |
|---|---|
| Conducts water and mineral salts from the roots to the aerial parts of the plant. | Translocates food from the leaves to the storage organs and growing parts of the plant. |
| Made up of tracheids, vessels, xylem parenchyma and xylem fibres. | Made up of sieve tubes, companion cells, phloem parenchyma and phloem fibres. |
| Conducting cells (vessels and tracheids) are dead. | Conducting cells (sieve tubes) are living. |
| Conduction is unidirectional. | Conduction is bidirectional. |
| Conduction does not require any expenditure of energy. | Conduction requires expenditure of energy. |
