Commercial fibres obtained from plants are The fibres support the conductive cells of the phloem and provide strength to the stem. Fibres are abundantly found in many plants. These fibres occur in the phloem pericycle wood fivres in xylem etc. Their walls are lignified. The fibres occur in all those parts where mechanical strength is required, viz., leaves, petioles, cortex, pericycle, phloem, xylem and around vascular bundles (e.g., monocot stem). Phloem is a heterogeneous tissue which is mainly composed of sieve tube, companion cell, phloem parenchyma and phloem fibres.
