TRANSPORTATION

Expert Answer:

In plants, transportation of water and food occurs through xylem and phloem respectively. Roots absorb water and minerals which is transported to the upper parts of the body, through xylem. Transpiration pull and root pressure are important in this transportation. No energy is required for this process.

Translocation on the other hand occurs through phloem where the products of photosynthesis are transported. The food is transported from leaves to other parts of the plant body through xylem. This process uses energy from ATP.
