Bast fibres are soft and flexible, as opposed to leaf fibres from monocotyledonous plants, which are hard and stiff. [2] Since the valuable fibres are located in the phloem, they must often be separated from the woody core, the xylem, and sometimes also from the epidermis.
In the embryo, root phloem develops independently in the upper hypocotyl, which lies between the embryonic root, and the cotyledon. [20] In an adult, the phloem originates, and grows outwards from, meristematic cells in the vascular cambium. Phloem is produced in phases. Primary phloem is laid down by the apical meristem and develops from the ...
Phloem fiber; Phloem parenchyma. Phloem is an equally important plant tissue as it also is part of the 'plumbing system' of a plant. Primarily, phloem carries dissolved food substances throughout the plant. This conduction system is composed of sieve-tube member and companion cells, that are without secondary walls.
However, Hilaire de Chardonnet was the first to patent a nitrocellulose fiber marketed as "artificial silk" at the Paris Exhibition of 1889. [53] Commercial production started in 1891, but the result was flammable and more expensive than cellulose acetate or cuprammonium rayon. Because of this predicament, production ceased early in the 1900s.

Low-VOC paint types include latex (water-based), acrylic, and milk paint, with most relatively easy to recycle. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC.
