The separation between plants that have veins and plants that do not is one of the great divides within the plant kingdom. This separates plants into vascular and non-vascular plants. Most plants have xylem and phloem and are known as vascular plants but some more simple plants, such as mosses and algae, do not have xylem or phloem and are known as non-vascular plants.

Phloem and xylem are closely associated and are usually found right next to one another. Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds.

Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems. Phloem The phloem carries important sugars, organic compounds, and minerals around a plant.

Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. Sieve-tube members Sieve-tube members are living cells that create chains of cells running the length of the plant.

The companion cell can sometimes also deliver sugars and other substances into the sieve-tube members from neighboring cells. Xylem The xylem is responsible for keeping a plant hydrated.

Two different types of cells are known to form the xylem in different plant groups: Tracheids are found in most gymnospermsfernsand lycophytes whereas vessel elements form the xylem of almost all angiosperms.

Xylem cells are dead, elongated and hollow. Tracheids Tracheids are long thin cells that are connected together by tapered ends. The tapered ends run alongside each other and have pits that allow for water to travel from cell to cell.

Their secondary cell walls contain lignin — the compound that creates wood. The lignin in tracheids adds structural support to the xylem and the whole plant.

Vessel elements Vessel elements are shorter and wider than tracheids and are connected together end-on-end. The perforation plates have a number of holes in their cell walls which allows for water to travel freely between cells.

Xylem and phloem in leaves Photosynthesis in leaves requires a lot of water from the xylem and produces a lot of sugar for the phloem. With the exception of lycophytes, veins divide multiple times in a leaf which creates a good spread of veins and makes it easier to collect sugars and deliver water to photosynthesizing parts of the leaf.

Vascular tissue also provides structural support to leaves. In eudicotsvascular bundles are arranged in a ring within the stem.The xylem is a tubular shape that has no cross walls which allows a continuous column of water and minerals a more rapid transport within the xylem, there are two types protoxylem first formed xylem and metaxylem mature xylem which depends on pattern of lignin, the phloem is an elongated tubular shape with thin walled sieve tubes.

The sieve. Mar 15,  · Cell wall is a fairly rigid, protective and supportive layer surrounding the cell external to plasma membrane of plants, bacteria, archaea, fungi and algae. Xylem is one of the two types of transport tissue in vascular plants, phloem being the other.

The basic function of xylem is to transport water from roots to shoots and leaves, but it also transports nutrients.

The word "xylem" is derived from the Greek word. Phloem and xylem are complex tissues that perform transportation of food and water in a plant.

Xylem is the tissue responsible for supporting the plant as well as for the storage and long-distance transport of water and nutrients, including the transfer of water-soluble growth factors from the organs of synthesis to the target organs.

Main Difference. Xylem Phloem are the vascular tissues that transport the food, minerals and water within the plant. Xylem transport the water and minerals while Phloem transport food and nutrients.

Phloem Xylem: Xylem is composed of four different kinds of elements, namely, tracheids, vessels, xylem fibres and xylem parenchyma. • Tracheids are elongated or tube like cells with thick and lignified walls and tapering ends.
