The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Also, the materials moving within the phloem are under pressure, which means that the cell walls of the phloem cells do not have to have as great a tensile strength. Why is phloem made of living cells, while xylem is made of dead cells? This active transport (called translocation) requires the cells to do work and use energy and can only be done while alive. 0 0 1. Unlike xylem, phloem vessels contain cytoplasm, and this goes through the holes in the sieve plates from one cell to the next. How do phloem cells compare to xylem cellss, and which are dead, which are alive??? principal function is the conducting of assimilates and food. Phloem actively transports sugars into a part of the phloem called sieve tubes. Phloem actively transports sugars into a part of the phloem called sieve tubes. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλοιός meaning "bark". 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; the other material that makes up the vascular plant transport system, the xylem, moves water and minerals from the root and is formed of non-living material. material in different plant parts judiciously. It is composed of sieve tubes (sieve tube elements) and companion cells. Copyright © 2020 Multiply Media, LLC. It is advantageous, in terms of rate of sap movement and the need to lift the sap against gravity to heights well above ground level, for a plant to have dead xylem elements in service for sap conduction from root to leaves. Primary xylem originates from the procambium during primary growth while secondary xylem has its origin in vascular cambium during secondary growth.
