Document Summary
Fibers are found in just about any plant organ. Fiber is a chain of long thin cells that are thread like with thick lignified walls. Sclerids are sclerenchyma cells that functions in structural support in fruits (also known as stone cells) Fiber cells are elongated, have tough cell wall. Plant cells: main component= cellulose, heat treatment= very resistant, dye treatment= adheres poorly, water treatment= great absorbent, pests= mostly resistant. Animal cells: main component= protein, heat treatment= very sensitive, dye treatment= adheres well, water treatment= poor absorbent, pests= very sensitive. All plant fibers are not alike: most valuable fibers are nearly pure cellulose and white, lignin and tannin tend to darken fiber, making it less valuable. Fibers are classified according to their associated plant organ. Surface fibers are usually associated with fruits and seeds. Leaf fibers are classified as hard fibers. Luffa aegyptiaca- skeleton is all fiber, used for bathing: are associated with the leaf veins of monocotyledonous plants.
