Document Summary

Demo bench objectives: examine the display of cork formation and a lenticel. Make sure you recognize the various layers of the structures. If macerated wood is available (chips of wood treated with strong acids and alkalis to separate the various cells), put a drop of suspension on a slide, cover with a coverslip, and look for fibers, tracheids and vessels. Are all softwoods soft?: explain and note items of interest for liriodendron wood. Compare this hardwood with displays of black ash (fraxinus nigra). What differences do you observe: examine the displays of pinus strobus and note items of interest. Make notes about how a bordered pit functions (see display). Compare this softwood to yellow cedar (chamaecyparis nootkatensis). What differences do you observe: examine displays of drimys. What is odd about this tree: using a dissecting scope, examine the 3 wood blocks provided (a, b, and c).
