Sap by the fact that phloem sap is physiologically extreme in terms of animal digestion, and it is hypothesized that few animals take direct advantage of this because they lack two adaptations that are necessary to enable direct use by animals. These include the existence of a very high ratio of non-essential/essential amino acids in phloem sap for which these adapted Hemiptera insects contain symbiotic microorganisms which can then provide them with essential amino acids; and also insect "tolerance of the very high sugar content and osmotic pressure of phloem sap is promoted by their possession in the gut of sucrase-transglucosidase
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
