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).
4. Fungi have cell walls made of chitin. The cellwalls of fungi are built of polysaccharides (chains ofsugars) and chitin, the same tough material a crabshell is made of. The cell walls of plants are made ofcellulose, also a strong building material. 5.Fungi have nuclear mitosis.Mitosis in fungi isdifferent from that in plants or most other eukaryotesin one key respect: the nuclear envelope does notbreak down and re-form.Instead, mitosis takes place within the nucleus.he cell walls of plants are made ofcellulose, also a strong building material. 5.
