Usage examples of "filaments".

The sensitive filaments are formed of several rows of elongated cells, filled with purplish fluid.

Circumnutation was observed in the above specified cases, either by means of extremely fine filaments of glass affixed to the radicles in the manner previously described, or by their being allowed to grow downwards over inclined smoked glassplates, on which they left their tracks.

As the filaments project at right angles to the surface of the leaf, they would have been liable to be broken whenever the lobes closed together, had it not been for the articulation which allows them to bend flat down.

Their hypocotyls were secured to sticks, and glass filaments bearing little triangles of paper were affixed to the cotyledons of both.

In those cases in which radicles with attached filaments were placed so as to stand up almost vertically, they curved downwards through the action of geotropism, circumnutating at the same time, and their courses were consequently zigzag.

A pinna was cemented with shellac on the summit of a little stick driven firmly into the ground, immediately beneath a pair of leaflets, to the midribs of both of which excessively fine glass filaments were attached.

Upright filaments were fixed to the hypocotyls of two seedlings, which stood vertically in the morning.

Extremely fine filaments of glass, bearing two minute triangles of paper, were fixed to the summits of young stems, frequently to the hypocotyls of seedlings, to flowerpeduncles, radicles, etc.

The whole upper surface is covered with glandbearing filaments, or tentacles, as I shall call them, from their manner of acting.

We shall hereafter see that the filaments on the leaves of Dionaea are likewise insensible to the impact of fluids, though exquisitely sensitive to momentary touches from any solid body.

I have seen two leaves with four filaments on each side, and another with only two.

These filaments are remarkable from their extreme sensitiveness to a touch, as shown not by their own movement, but by that of the lobes.

These filaments, from their tips to their bases, are exquisitely sensitive to a momentary touch.

Although these filaments are so sensitive to a momentary and delicate touch, they are far less sensitive than the glands of Drosera to prolonged pressure.
