Homework Help: Science: Biology: Cotton

It is almost impossible to determine the original habitats of the various species of cotton. Scientists have determined fiber and boll fragments from the Tehuacán Valley of Mexico to be about 7000 years old.

Cotton is produced by small trees and shrubs of a genus belonging to the mallow family, which also includes hibiscus, okra, and the familiar swamp mallow.

The length of the individual fibers ranges from 1.3 to 6 cm (0.5 to 2.5 in). Shorter fibers that grow from the seeds are called linters.

Cotton was used also by the ancient Chinese,Egyptians, and North and South Americans.
