WebThe xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant. It is also used to replace water lost during transpiration and photosynthesis. WebPlants do not have a heart, blood or a circulation system, but they do need a transport system to move food, water and minerals around. They use two different systems - xylem moves water and...

Transport in plants and the structure of specialised plant cells
WebJan 15, 2024 · The xylem transports mostly water. Starches are not very soluble in water, so dissolving and transporting them in water is not likely. Sugars like glucose and … WebFigure 1. (a) Phloem is comprised of cells called sieve-tube elements. Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Lateral sieve areas connect the sieve-tube elements to the companion cells. WebIn the chloroplast, light energy is captured and the first steps are taken in the chemical pathway that converts the energy in light into forms of energy that the plant can transport and store, like sugar and starch.
