How has the phloem cell adapted
WebStructure Of The Phloem Tissue: This is a long tube that runs alongside the xylem tissue. They are made of long narrow tubes with perforated sieve plates along the thin length. The function of the phloem tissue is to transport food nutrients such as glucose and amino acids from the leaves and to all other cells of the plant, this is called translocation. WebThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant.

Web27 jun. 2024 · Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body. It is typically composed of three cell types: sieve elements, parenchyma, and sclerenchyma. WebPhloem cells form tubes similar to xylem vessels, except the cells still retain some subcellular structures and are therefore living Function: transport of dissolved sugars (e.g. sucrose) and amino acids Adaptations: Made of living cells (as opposed to xylem vessels, which are made of dead cells) that are supported by companion cells
