The cells in the phloem need to be alive to provide energy for active transport when transporting sucrose around the plant. The phloem cells are laid out end-to-end throughout the entire plant, transporting the sugars and other molecules created by the plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. What are the structural, functional and metabolic differences between xylem and phloem?

Phloem actively transports sugars into a part of the phloem called sieve tubes. What does contingent mean in real estate? The non-green parts are depended on the photosynthetic cells for nourishment. Yes, Phloem cells are alive. Phloem consists of living cells arranged end to end. Therefore phloem is a cell which is made of specialized tissue known as “Vascular tissue” that allows conductance of food in the vascular plants. Xylem tissue dies after one year and then develops anew (rings in the tree trunk). And so xylem cells can afford to lose all of their stuff because they are dead, right? Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. This active transport (called  translocation) requires the cells to do work and use energy and can only be done while alive. In their lifestyles and beliefs, the Beats celebrated all of the following EXCEPT. Structure: At maturity, xylem is a dead tissue, with no cell content. The perforated end wall of a sieve tube is called a sieve plate. Companion cells, sieve-tube elements, fibers and parenchyma are all parts of the phloem, which is a vascular tissue necessary for the transport of sugars, proteins and mRNAs from source to sink in plants. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’. 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.
