Sap Sap Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Sap is distinct from latex, resin, or cell sap; it is a separate substance, separately produced, and with different components and functions. Saps may be broadly divided into two types: xylem sap and phloem sap. Xylem sap (pronounced ) consists primarily of a watery solution of hormones, mineral elements and other nutrients. Transport of sap in xylem is characterized by movement from the roots toward the leaves. Over the past
Japanese tissue Japanese tissue Japanese tissue is a thin, strong paper made from vegetable fibers. Japanese tissue may be made from one of three plants, the "kōzo" plant ("Broussonetia papyrifera", paper mulberry tree), the mitsumata ("Edgeworthia chrysantha") shrub and the gampi tree ("Diplomorpha sikokiana"). The long, strong fibers of the kōzo plant produce very strong, dimensionally stable papers, and are the most commonly used fibers in the making of Japanese paper (washi). Tissue made from "kōzo", or kōzogami (楮紙), comes in varying thicknesses and colors, and is an ideal paper to use in the mending of books. The majority of mending tissues
