The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’. Ask your question. This active transport (called translocation) requires the cells to do work and use energy and can only be done while alive. Main Difference – Xylem vs Phloem. Why are the end walls not completely gone like in the xylem? The cells that make up the phloem tissues need to be alive to facilitate the active transport of sucrose throughout the plant. Top Answer.

Click here to get an answer to your question ️ xylem=phloem=In both cells dead or aliveFunction direction of flowcytoplasmpermeability 1. 1. Lignin gives strength and support to the plant. Copyright © 2020 Multiply Media, LLC. With our help, your homework will never be the same! Are phloem cells alive? Phloem cells are alive at maturity, mainly because movement of materials within the phloem requires energy. And so xylem cells can afford to lose all of their stuff because they are dead, right? 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. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements. Phloem cells are alive, using ATP to actively move the sugars from the leaves to the phloem. Phloem originates from meristematic cells in vascular cambium- primary phloem from apical meristem and secondary phloem fr… This ... What did one 1920s observer describe as the same to business as fertilizer was to the farm? For details use the links please. Xylem is formed by tracheary elements like tracheids and vessels predominantly. principal function is the conducting of assimilates and food. Phloem. Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. Food is synthesized in the green parts of a plant. Companion cells contain the cell nuclei. Xylem contains heterogeneous cells in structure and function like parenchyma cells, xylem fibers, vessels, and tracheids. All Rights Reserved. How many candles are on a Hanukkah menorah? Learn Phloem with free interactive flashcards. Why don't libraries smell like bookstores? This active transport (called translocation) requires the cells to do work and use energy and can only be done while alive. Phloem has life cells. The formation of sieve plates between phloem sieve-tube elements allows. Phloem actively transports sugars into a part of the phloem called sieve tubes. Answer. What are the structural, functional and metabolic differences between xylem and phloem? 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.
