The movement of products of photosynthesis is called translocation, and it occurs in the phloem, a part of the vascular tissue.

Root pressure is more important at night, while during the day, when stomata are open, transpiration pull becomes the major driving force for the movement of water in the xylem.

Transpiration aids in the absorption and upward movement of water and dissolved minerals from roots to leaves, facilitated by the suction effect created during leaf cell evaporation.

Water lost through stomatal transpiration is replaced by water from xylem vessels in the leaf, driven by the suction created through evaporation from leaf cells.

The pressure created by water movement into the root xylem is unlikely to move water over significant heights. Plants employ another strategy, possibly involving transpiration and cohesion, to move water upwards in the xylem to the highest points of the ...

Cells in contact with the soil actively take up ions at the roots, creating a concentration difference. Water moves into the root xylem from the soil to eliminate this difference, establishing a steady upward flow.

The vessels and tracheids of the roots, stems, and leaves are interconnected in the xylem tissue, forming a continuous system of water-conducting channels that reach all parts of the plant.

Very tall trees face the challenge of large distances for transport systems. Despite this, plants have independently organized conducting tubes (xylem and phloem) to efficiently move energy stores from leaves and raw materials from roots.

Xylem transports water and minerals from the soil to various parts of the plant, while phloem moves products of photosynthesis from leaves, where they are synthesized, to other plant tissues.

Plants have low energy needs as they do not move and contain a significant proportion of dead cells. This allows them to use relatively slow transport systems.
