Write what produces the fibres below

a)Cotton. c)Wool
b)Linen. d) Silk

a) Cotton - Cotton fibers are produced from the cotton plant, specifically from the fluffy fibers surrounding the seeds of the cotton plant, which is a genus Gossypium in the mallow family, Malvaceae. These fibers are spun into yarn or thread to create a soft, breathable textile.

b) Linen - Linen fibers are produced from the stalks of the flax plant, Linum usitatissimum. The fibers are located in the bast (the phloem of the plant), which must be separated from the rest of the stalk through a process called retting. Linen is valued for its strength and its cool, smooth texture well suited for warm weather.

c) Wool - Wool fibers are produced from the fleece of sheep or other animals like goats (cashmere and mohair), rabbits (angora), and some types of camel. Wool is crimped, elastic, and often has a natural waviness. It is spun into yarn for producing warm clothing and other textile products.

d) Silk - Silk fibers are produced by silkworms, which are the larvae of moths (primarily Bombyx mori). During the cocoon stage, the silkworms secrete a continuous filament of silk which is a protein substance called fibroin. This filament can be unwound to produce silk threads. Workers boil the cocoons to kill the silkworms and dissolve the gummy sericin, then unreel the silk filaments which are then spun into silk threads.
