Question

From which part of the cotton plant (Gossypium), maximum cellulose fibre can be obtained?
A. Root hair
B. Seed hair
C. Stem surface
D. Leaf surface

Answer 1

Hint: Bast, leaf, and seed-hair fibres are cellulose-based fibres. Flax, hemp, jute, and ramie are bast fibres that emerge from the plant's stem. Manila and sisal are two leaf fibres that are extracted from the plant's leaves. Cotton and kapok seed-hair fibres are obtained from seeds or seed casings.

Complete answer:
Cotton is the most well-known and widely used natural cellulosic fibre, derived from the cotton seed. Cotton fibre is made up of 87 percent to 90 percent cellulose and 5 percent to 8% water in the field, with the rest being natural impurities. The amount of cellulose in the fibre rises as it matures.
In textiles, large quantities of immature cotton fibres can cause a variety of issues. Cotton's moisture content fluctuates with storage circumstances, while the quantity and types of contaminants vary with growth area, fertiliser, and variety.
Cotton is the seed-hair fibre of a variety of plants of the genus Gossypium, which belongs to the hibiscus or mallow family (Malvaceae) and is native to most of the world's subtropical regions. The fibre is almost entirely made up of cellulose. Cotton bolls have a tendency to promote seed dispersion under natural conditions. As a result, option B is right.
Cotton is a natural (vegetable) fibre derived from the cotton plant's seed. It is a polysaccharide or polymeric sugar. Cotton fibre is particularly well suited for most garment and home end purposes because of its combination of strength, durability, and comfort qualities.
Cotton also has a high temperature resistance, which is crucial in the dyeing and finishing operations in textile mills, as well as in consumer care.

Note: Cotton fibre is made up of four basic components:
-The cuticle, a waxy coating that repels water and acts as a lubricant.
-The main wall, which includes natural impurities.
-The second wall, which is made entirely of cellulose.
-The lumen, which is an open space in the fiber's middle through which nutrients flow.
