phloem means: The tissue found in vascular plants. The main purpose of this tissue is to carry sugars and other foods materials, such as amino acid, from the leaf to other parts. It could go from the leaf to the root to supply the growth chemicals. It could come from the leaf, or even a fruit in development that has high levels of sugars. Photosynthesis is what makes sugars. This happens in the green part of plants like leaves. Amino acids are formed from sugars, minerals and nitrates absorbed from soil. Phloem tissue can be found near xylem which is the transport tissue for water and minerals in plants. Non-woody plants have phloem, xylem in bundles such as leaf veins. Phloem is made up of Sieve elements, their companion cells and some types of sclerenchyma or parenchyma cells. The sieve elements consist of long thin cells with thin walls joined together to form sieve tubes. Large pores allow for continuous flow of nutrients through the wall. The xylem water-conducting tissue is often found with Phloem. However, it is not a living tissue. (in Community Dictionary, added by Kelsie Harris)

  • This tissue is the part of vascular plants that transports photosynthesis-produced food to all areas of the plant. It consists of fibers and sieve elements. (in AZ Dictionary)
