(1) Fibre (Fibre cell) [ Botany ]


	In botany a fibre is an elongated plant cell with tapering, pointed ends that has walls thickened with lignin and is a major component of the plant’s supporting and strengthening tissue (sclerenchyma)

Fibre cells are frequently found in the outer walls of plant stems and interlock to form a strong, rigid tissue that usually occur in bundles or strands. See: fibre cell

(2) Fibre (Fibrous root) [ Botany ]


	A fibre is a thin narrow root one of the slender rootlets of a plant

(See: Fibrous root and Fibrous root system )

(3) Fibre (Natural fibre) [ Botany ]


	A natural vegetable fibres is a long, thin, and strong fibre capable of being spun into yarn, generally consist of cellulose

For examples the cotton or the fibres of Agave sisalana .

(4) Fibre (Fibre plant) [ Botany ]

Holdfast roots [ Botany ]
Dictionary of botanic terminology - index of names

Some species of climbing plants develop holdfast roots which help to support the vines on trees, walls, and rocks. By forcing their way into minute pores and crevices, they hold the plant firmly in place.

Climbing plants, like the poison ivy (Toxicodendron radicans), Boston ivy (Parthenocissus tricuspidata), and trumpet creeper (Campsis radicans), develop holdfast roots which help to support the vines on trees, walls, and rocks. By forcing their way into minute pores and crevices, they hold the plant firmly in place. Usually the Holdfast roots die at the end of the first season, but in some species they are perennial. In the tropics some of the large climbing plants have hold-fast roots by which they attach themselves, and long, cord-like roots that extend downward through the air and may lengthen and branch for several years until they strike the soil and become absorbent roots.
