Question
What are the differences between the transport of materials in xylem and phloem?
Solution
| Transport of materials in xylem | Transport of materials in phloem |
| Xylem involves the transport of water and minerals from the soil via roots to the rest of the plant body. | Phloem involves transport of food materials from the leaves to different parts of the plant body. |
| Movement of water is unidirectional, i.e. upwards from the roots to the aerial parts of the plant. | Movement of food is bidirectional, i.e. both upward and downward. |
| Transport of material in xylem requires physical forces such as transpirational pull. | Transport of material in phloem requires energy in the form of ATP. |

The transport system in plants consists of two kinds of tissues X and Y. The tissue X is made up of living cells and consists of two components A and B. The component A has tiny pores in its end walls and contains only cytoplasm but no nucleus. On the other hand, component B has cytoplasm as well as nucleus. The tissue Y is made up of dead cells and consists of two components C and D. The component C has open ends whereas component D does not have open ends. In flowering plants, either only C or both C and D transport water but D is the only water conducting tissue in non-flowering plants.
