If water be driven into the pores of wood the latter becomes heavier than water, as the lignin of which it is composed has a density of about 1ยท6.
The woody matter consists principally of fibrous tissue on to which the lignin or so-called incrusting matter has been deposited.
Every year a layer of lignin is deposited on this part by the juices which are absorbed by the roots and drawn up by the leaves; for this reason the age of trees may be determined by the number of lignin layers deposited.
Any number of things: Perhaps theLignin in the nerve paths was poisonous.
Like tropical rains from a jungle roof, lignin dripped from the vaults, and in falling, burst into flames.
A main nerve stem burst asunder and the lignin poured from its cracked plastic walls like crude oil from a burning gusher, rushing over acres of electronic tubes, branding against banks of radioactive pyramidal cells, swamping them as a wave.
Down at his feet the spilled lignin formed a widening pool; it threatened to envelope his feet.
With the third blow the plastics cell cracked and the lignin poured out, a syrupy curtain sliding down.
The lignin material generally consists of two types of substances, one of which contains a closed-ring nucleus of unknown composition and the other is probably a pentosan.
In the preparation of wood pulp for the manufacture of paper, the ligninmaterials are dissolved off by means of various chemical reagents, leaving the cellulose fibers in nearly pure form for use as paper.
Cellulose and lignin are the two substances that make up the hard, permanent, and woody parts of plants; these materials cannot be digested by most soil animals.
Some of these differences are due to variations in lignin content which is highly resistant to decomposition, but speed of decomposition is mainly influenced by the amount of protein and mineral nutrients contained in the leaf.
The amount of pentosanes in the Schweizer extract was relatively greater in the second than in the first year, but decreased in the lignin more in the second year than in the first: this result is also given with reserve.
In the second year the ligninalone increased to the end; the cellulose decreased at the end of June.
In the first year it seemed an absolutely as well as relatively greater amount of cellulose, and lignin was produced in the second year; this, however, requires confirmation.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "lignin" in a variety of sentences. We hope that you will now be able to make sentences using this word.
