Question

Answer

Silk is animal fibre

Answer

Silk is not a plant fibre because plant fibre is the fibre we obtain from plants such as jute ,but silk is obtained from silk worm that is a kind of insect not a plant hence silk is not a plant fibre

Answer

Silk is not plant fibre,,, but,,, it is Animal fibre...

Answer

Silk is a animal fibre and obtained from silk worms

Answer

Explanation:

Introduction:
Plant fibers are fibers obtained from various parts of plants, such as stems, leaves, and seeds. These fibers have been used for various purposes for thousands of years, including making fabrics, ropes, and paper. They are versatile, renewable, and biodegradable materials.

Options:
a) Coir: Coir is a natural fiber extracted from the husk of coconuts. It is commonly used in making ropes, mats, and brushes. Coir is a plant fiber.

b) Flax: Flax is another natural plant fiber that is obtained from the stem of the flax plant. It is commonly used in the production of linen fabric. Flax is a plant fiber.

c) Hemp: Hemp is a plant fiber derived from the Cannabis sativa plant. It is known for its strength and durability and is used in making textiles, ropes, and paper. Hemp is a plant fiber.

d) Silk: Silk is not a plant fiber; it is an animal fiber. Silk is produced by silkworms, which spin cocoons made of silk fibers. These fibers are then harvested and used to make silk fabric.

Conclusion:
Silk is not a plant fiber; it is an animal fiber. The correct answer is option 'D'.

Answer

Silk is obtained from silkworm not from any plant whereas hemp, coir and flax are obtained from plants thus, silk is the correct answer.

Answer

Most crop residue can be processed as cellulose. The cost of many of them isn't worth the effort unless there are some special circumstances such as being the only source within 800 miles.

Cotton, Jute, Hemp and Flax are the big ones as crops. On a smaller scale Nettles, Yucca, Luffa, and fibers taken form the wild make most of what comes off the farm.

Bamboo, Papyrus and wood products are managed as forests on much more complex continuous harvest management plan than annul corps.

Rice fiber for paper may be a specialty crop like some wheat is grown for thatched roofs in the UK but their considered by byproducts.

Silk is animal husbandry not a crop. The crop is mulberry leaves you feed silk worms.

Silk may soon be pharming operation. There are transgenetic goats that make spider silk protein in their milk. I don’t see why yeast couldn't make it as well. The protein may be too complex for yeast to metabolize. Rayon was one of our first efforts at man made cotton. I was failure. The microfiber that resulted form rayon, mixed with 40% cotton makes really nice shirt. None of the cotton fiber grown in the laboratory are good enough or cheap enough to bring to market but their better than Rayon was.

We are nearing a place that the tools in genetic research and computing have nearing the point in the economies of scale the limiting factor is ideas and effort not time, money or machinery. These will make the thing like cotton fibers grown in vats of yeast possible freeing up some of the best soil in the world to gtoe eomr

One must be clever but the world is theirs if they can visualize it. I feel that’s true in many fields today for those that have the courage to reach out and take the risks and reap the rewards and occasional failures. If you fail pick another one the looks good and hook your spurs in the cinch and ride it.
