Question

The fibers of Gossypium are

Answer 1

Hint: The fibers which are collected from seeds of a number of plants are known as seed fibers. These fibers are used in making durable yarn, packaging, fabric, and paper. Some examples of seed fibers are jute, flax, kenaf, ramie, and industrial hemp, rattan, and vine fibers.

Complete answer: Cotton, seed-hair fiber or testa are a range of plants belonging to the genus Gossypium which belongs to the Hibiscus or mallow, and the family Malvaceae. These are native to most of the subtropical parts of the world. Gossypium is a genus of flowering plants or angiosperms belonging to the tribe Gossypiella of the mallow family, Malvaceae. Cotton is harvested from the family Malvaceae. Gossypium is native to the tropical and subtropical regions of the Old and New Worlds. Cotton is a soft and fluffy staple fiber grown in a boll or a protective capsule that grows all over the seeds of the plant. These fibers are nearly pure cellulose. The cotton bolls incline to increase the dispersion of the seeds under natural conditions. So, the fibres of Gossypium is the outgrowth of the testa and are not the outgrowth of pericarp or pappus hair or bast fibres.
So, the correct answer is option C.

Note: Most of the wild cottons are diploid in nature. But a group of five specific species from America and Pacific islands are found to be tetraploid, seemingly because of a single hybridization event that occurred around 1.5 to 2 million years ago. The tetraploid species include G. hirsutum, G. tomentosum, G. mustelinum, G. barbadense, and G. darwinii.
