Sieve tubes are specialized structures within the phloem responsible for transporting nutrients. They contain pores called sieve plates through which nutrients flow. Sieve tubes are assisted by adjacent companion cells, which provide metabolic support and help regulate nutrient transport.

The substances transported by the phloem are especially directed to storage organs such as roots, fruits, and seeds, as well as to growing organs where they are needed for growth and development.

In addition to the products of photosynthesis, the phloem transports amino acids and various other substances essential for plant growth and metabolism.

Translocation is the movement of soluble products of photosynthesis and other substances throughout a plant. This process occurs in the phloem, a specialized vascular tissue responsible for transporting organic nutrients.

Transpiration facilitates the movement of water and dissolved minerals from the roots to the leaves. As water is drawn upward through the xylem, it carries minerals dissolved in the soil solution, ensuring their transport to all parts of the plant ...
