Bushings are one of those things that most people don't really think about until they find out they have a $600 mechanic's repair bill on their hands. Some even think the mechanic is trying to rip them off when they mention bushings needing replaced.
Lignin is a phenolic compound, chemically related to benzene. The cell walls of fungi are diverse among the taxonomic groups, but most contain chitin microfibrils embedded in a polysaccharide matrix and covered with a loose coating of additional molecules combining sugars and peptides (amino acid chains).
cell wall-Complex, with peptidoglycan (and in gram negatives, lipopolysaccharide). cell wall-Chemically simple, in plants (the polysaccharides cellulose and pectin as well as the phenol polymer lignin) and fungi (the polysaccharide chitin). no membrane bound organelles-but there are numerous inclusions and granules. Numerous small ribosomes in cytoplasm.
