Question

Mark the fibre yielding plant 'Patsan' of Malvaceae
a) Malvaviscus arboreus
b) Hibiscus cannabinus
c) Althea rosea
d) Malvastrum tricuspidatum

Answer 1

Fibre crops or plant fibres are also referred to as natural fibres because they are obtained naturally and straightforwardly from various wellsprings of plants and their products. These fibre crops are notable for their length, width, tenacity, consistency, turning malleability, and adaptability. Cotton, jute, coir, hemp, and flax are the various sources of plant filaments.

Complete answer:
Filaments are a section of the plant skeleton of sclerenchyma cells which is related to vascular tissue. The cells are long with sharp ends. They are the harsh materials that become yarn and textures as flimsy, long strings and suitable strings.
Normal fibres were used to assemble the material, paper, cables and so on before the presentation of the designed fibres. In the assembly companies the fibre crops were the source of these characteristic fibres. Because cellulose is present, these strands are extremely strong.
Almost all members of the Malvaceae family yield bast filaments, which can be used in materials. Other malvaceous species include Indian Mallow (Abutilon theophrasti), Kenaf (Hibiscus cannabinus), Roselle (Hibiscus sabdariffa), and Okra, Hibiscus esculentus , Sida acuta , and Hibiscus tiliaceus. Hibiscus cannabinus is also known as Sougri, Sann, and Patsan. A greasy oil derived from patsan seeds is used in the manufacture of paints, stains, and tile, and its refined oil is edible. Its fibre is used to make ropes, veil, belts, convey packs, and enhancing items.

Hence, option B-Hibiscus cannabinus is the correct option.

Note:
Three classes of fibre plants are assembled: material strands, cordage filaments, and filling strand. The increasing demand for artificial fibres such as nylon is making plant fibres less significant. Artificial fibres are more durable and stronger than natural fibres, are cost-effective and resistant to chemicals.
