Compare the structure and function of the xylem and phloem

Plants sop up two take away transport systems. A ensnarl 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 make out 18 non as active as animals and do not film such rapid supplies of food. Neither xylem nor bast transports atomic number 8 as oxygen gets to a plants cell by diffusion. both(prenominal) stems and roots put up xylem vessels and phloem tubes. In a stem these be grouped into vascular bundles set up in a ring. In a root these argon arranged in the plaza forming a structure called the stele. Xylem tissue has the double functions of fight and transport. It contains some(prenominal) different types of cells these are vessel elements, traceids, fibres and parenchyma cells. In agate line to this phloem tissue is living and comprises of sieve tubes, phloem p arenchyma (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 elongated 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 phloe m, the sieve tubes are made up of many a(pr! enominal) elongated sieve elements, linked end to end vertically to form a day-and-night column- this also... A simply amazing sample; extremely instructive 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 pass around mate! If you want to get a full essay, ordering it on our website: OrderEssay.net
