Answer:
(a) Cotton is obtained from the fruit of the cotton plants. The cottonseed which is a fruit which on ripening splits open to release white fibers of cotton. (b) Jute is obtained from the stem of the jute plant. ... So jute is obtained from stems of the jute plan.
Jute plants are harvested or cut at the time of the flowering stage because at this stage plant contains more of fibres and we obtain a good quality of fibre. If it is allowed to grow after the flowering and then harvesting is done after-ripening of seeds, then the fibre lacks lustre and elasticity.
