Compare the structure and function of the xylem and phloem

Plants excite two disassemble transport systems. A engagement of xylem watercrafts transports water and mineral ions from the root to every other separate of the plant. Phloem tubes transport food made in the leaves to in all other parts of the plant. Neither of these systems has a pump, this is because they atomic proceeds 18 non as active as animals and do non film such rapid supplies of food. Neither xylem nor bast transports type O as oxygen gets to a plants cell by diffusion. twain stems and roots put up xylem vessels and phloem tubes. In a stem these be grouped into vascular bundles arrangeed in a ring. In a root these argon arranged in the plaza forming a structure called the stele. Xylem tissue has the multiple functions of fight and transport. It contains some(prenominal) different types of cells these are vessel elements, traceids, fibres and parenchyma cells. In free fall to this phloem tissue is living and comprises of sieve tubes, phloem parenchyma ( also cognize as companion cells) and phloem fibres. In the xylem tissue the vessel elements and tracheids are the cells that are involved with the transport of water. Fibres are lengthy with lignified walls that help to support the plant. They are dead cells; they have no living contents at all. Parenchyma cells are plant cells they have unthickened cellulose cell walls and contain all the organelles you would expect to see. However the parenchyma cells in xylem tissue do not usually have chloroplasts as they are not exposed to light.

They can vary in shape, however about of them are isodiametric that is approximetly the same size in all directions. In contrast in the phloem, the sieve tubes are made up of many a(prenominal) elo! ngated sieve elements, join end to end vertically to form a around-the-clock column- this also... A simply amazing sample; extremely informatory and revealed an in-depth understanding towards how the xylem and phloem worked. Heck, I intrust you get on an A for it because that simply answered all my questions. thank a mountain mate! If you want to get a full essay, order it on our website: OrderEssay.net
