cell-walls

No. 6 is a section of a Potato tuber: A, the cell-walls; B, the starch grains; C, the mycelial hyphæ.

No. 5 affords a view of another piece of tissue of the stem of a Potato plant, and shows the hyphæ of = Phytophthora infestans = running in the cell-walls; (= a =) nucleus of a cell; the other contents shown are crystals and chlorophyll corpuscles.

As common adaptive features in the leaves the occurrence of papillae or outgrowths of the cell-walls to retain water, and the white hairlike leaf tips, which assist in protecting the young parts at the apex of many xerophytic mosses, may be mentioned.

For the first thread it spins is manifestly for its own covering or the ornamentation of its own cell-walls.

The animal body, if it be composed of many cells, follows a different architectural plan; the compact nature of its food, and the yielding nature of its cell-walls, result in a form of structure consisting essentially of tubular or spherical masses of cells arranged concentrically round the food-cavity.

The cell-walls are capable of imbibing water rapidly, and their thickness stands in relation to this rather than to the prevention of loss of water from the plant.

In spite of this, however, they are in great part dependent on the absorption of water through the general surface of the shoot, and the power of rapid imbibition possessed by their cell-walls, the crowded position of the small leaves on the stem, and special adaptations for the retention of water on the surface, have the same significance as in the foliose liverworts.

These are the thickened cell-walls of a definite layer of cells (p), and appear [v. 04 p. 0651] as separate teeth owing to the breaking down of the unthickened cell-walls.

In most mosses the teeth are portions of thickened cell-walls but in the Polytrichaceae they are formed of a number of sclerenchymatous cells.

No chemical change has yet intervened to break down their cell-walls, or interfere with the occupations assigned them.
