Dictionary entry overview: What does phloem mean? 4 minutes ago by. Transportation In Plants. Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant.These cells transport water and nutrients throughout the plant.. Sap is distinct from latex, resin, or cell sap; it is a separate substance, separately produced, and with different components and functions. Biology. In plant biology, the secondary phloem is a part the cambium vascular growth of a tree or woody plant. Biology. 9th grade . Translocation is the movement of materials from leaves to other tissues throughout the plant. Play this game to review Biology. The phloem is made up of living tissue which uses turgor pressure and energy in the form of atp to actively transport sugars to the plant organs such as the fruits flowers buds and roots. phloem meaning: 1. the type of plant tissue that transports food from the leaves to the other parts of the plant 2…. Learn how plants transport sugars via the phloem (translocation) and water via the xylem (transpiration) between the roots and leaves. Biology | Phloem. Four independent phloem strands grow between each bar of the xylem cross. In vascular plants, phloem is the living tissue made up of small tubes which carry watery sap containing sugar and other organic nutrients to all parts of the plant where the nutrients are used for growth, or stored until needed. Known as translocation, this transport process ensures the proper growth and development of the plant. Xylem & Phloem Vessels, this A-Level Biology section of Revision Science explains xylem and phloem vessels. Phloem is tissue where substances can flow up and down to carry the food throughout the plant. The different elements of phloem include sieve tubes, companion cells and phloem parenchyma and phloem fibres. Edit. Phloem is a complex tissue of a plant which was first introduced by a scientist Nageli in the year 1853.It is a part of the vascular system in a plant cell which involves the translocation of organic molecules from the leaves to the different parts of plants like stem, flowers, fruits and roots..
