Libriform fibers are long pit-containing cells found throughout this tissue, and perforation plates found at the ends of this tissue can be described as simple, foraminate, or scalariform.
Libriform fibers are long pit-containing cells found throughout this tissue, and perforation plates found at the ends of this tissue can be described as simple, foraminate, or scalariform. The primary type of this tissue is located closest to the pith, and it is made up of tracheid vessels in most conifers with trachea elements performing most of its function. This tissue must use the evaporation of water at mesophyll cells in leaves and negative back-pressure at the roots to carry out its function in a process called transpirational pull, which allows water and minerals to travel up through plants.  For 10 points, identify this dead vascular tissue in plants that functions differently from phloem.
