The function of the phloem are:- The phloem collects photo assimilates in green leaves,distributes them in the plant and supplies the heterotrophic plant organs. Phloem tissue transports and distributes sucrose and nutrients produced by the plant during photosynthesis Phleom Phloem tissue is a living tissue that carries food material , from the place it is available to the place where it is needed . It transport the organic material usually from leaves to other part of the plant like , root , growing tips of stem and leaves, flower, fruit etc . The food prepared in the leaves through the process of photosynthesis needs to be transported to each and every. Phloem (/ ˈfloʊ.əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation

Phloem or bast is a complex, permanent tissue of vascular plants which conducts organic food. Its elements were discovered by Hartig (1837). The term was coined by Nageli (1858). Phloem consists of four types of elements- sieve cells or sieve tube elements, companion or albuminous cells, phloem parenchyma and phloem fibres Phloem parenchyma cells, called transfer cells and border parenchyma cells, are located near the finest branches and terminations of sieve tubes in leaf veinlets, where they also function in the transport of foods. Phloem fibres are flexible long cells that make up the soft fibres (e.g., flax and hemp) of commerce

Components of Phloem Tissue. The phloem tissue is made up of several various components. Each of these components performs functions by working together, these functions include facilitating the conduction of sugars and the amino acids, from source tissues to the sink tissues where they are consumed or stored. The elements of phloem are as follows Although several phloem sap proteins have been identified from protein extracts of heat-treated Arabidopsis seedlings using FPLC gel filtration columns, many of the physiological roles played by these proteins remain to be elucidated. We functionally characterized a phloem protein 2-A1, which encodes a protein similar to phloem lectin

  3. Phloem sap has a high pH (7-8) and contains high concentrations of solutes, on average 15-25% dry matter. A comprehensive analysis of phloem sap composition is shown in Table 3.8.The main component is usually sucrose, which may comprise up to 90% of the solids. The proportion of sucrose to other solutes depends on the site of phloem sap collection; it can be very high at the loading sites.

The hypothesis of Phloem Translocation. From the 1930s to the mid-1970s, the mechanism of phloem translocation was a subject of research. Now, one theory is generally accepted as the correct explanation for translocation. This theory called the pressure-flow hypothesis is favored by most plant physiologists and was proposed by E. Munch in Germany in 1926 The plant anatomy of the higher class plants such as angiosperms and gymnosperms contains an excellent system of transportation of water and organic compounds. One of the prime tissues that constitute this transportation system is the phloem. This tissue is made of a cluster of sieve tubes and other complex cells to cater to the functions
