It is also to be noted as a significant fact, that the cellulose wall was intact at the apex, instead of showing the opening through which in ordinary cases the gonidium escapes.
But they live chiefly on half-decayed leaves; and these would be useless to them unless they could digest the cellulose forming the cell-walls; for it is well known that all other nutritious substances are almost completely withdrawn from leaves, shortly before they fall off.
In awe they looked down at the mighty rock masses, as they swung low over the mountains, gazing in wonder at the green masses of the strange vegetation; strange, indeed, for they for uncounted ages had grown only mushroom-like cellulose products, and these mainly for ornament, for all their food was artificially made in huge factories.
Hard Wheat, or that grown in hot climates and on fertile soil, has much more nitrogen than that of colder countries. In hard wheat, in a hundred parts, twenty-two will be of nitrogen, fifty-nine starch, ten dextrine, &c, four cellulose, two and a half of fatty matter, and three of mineral, thus giving many of the constituents found in animal food.
Here also belong the gums and cellulose found in fruit, cereals, and all vegetables which form the basis of the plant cells and fibers. Honey, molasses, and manna are included in this class. The physiological value of the starches and sugars lies in the fact that they are oxidized in the body, and a certain amount of energy is thereby liberated.
After six generations the strength of the spawn decreases and the yield of the mushrooms will be less. Substratum: Paddy straw is the main substratum used for growing mushrooms-it contains cellulose and lignin, both of which are necessary for the growth of mushrooms.
Yet in so doing he had no intention of subordinating the cell wall. The fact that Payen, in 1844, had demonstrated that the cell walls of all vegetables, high or low, are composed largely of one substance, cellulose, tended to strengthen the position of the cell wall as the really essential structure, of which the protoplasmic contents were only subsidiary products.
"Carbon and oxygen constitute about ninety per cent. of the dry matter of ordinary farm crops, and with the addition of hydrogen very important plant constituents are produced; such as starch, sugar, fiber, or cellulose, which constitute the carbohydrate group. As the name indicates, this group contains carbon, hydrogen, and oxygen, the last two being present in the same proportion as in water.
Before long, the complex hydrocarbons and cellulose would all be innocent little molecules of carbon, oxygen, hydrogen; they might turn up in new combinations as sugar on the table! The Mentorian grumbled, "You young people think the rules mean everybody but you," and strapped him far too tightly into the bunk.
As cellulose usually surrounds nutritive material of vegetable origin, it must be softened and loosened sufficiently by cooking to permit the nutritive material to be dissolved by the digestive juices. Then, too, in old vegetables, there is more starch and the cellulose is harder and tougher, just as an old tree is much harder than a sapling.
