प्रश्न
What are the differences between the transport of materials in xylem and phloem?
उत्तर
| 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. |
