Answer:
(1) Ropes as per their need should have high tensile strength as well as should be quite flexible. Natural ropes such as made from jute or hemp are but the phloem/ bast fibres. These fibres, surely provide plant, mechanical strength.
(2) Cotton is obtained from the fruit part of plant
(3) Coir, seed-hair fibre obtained from the outer shell, or husk, of the coconut, the fruit of Cocos nucifera, a tropical plant of the Arecaceae (Palmae) family.
(4) In which state of our country, jute growing is a major source of income.
Hope it helps!
Please mark this as the brainliest answer!!!
1. BECAUSE THE FIBRES WHICH ARE OBTAINED FROM PARTS OF PLANTS THAT CONTAIN BAST FIBRES , SOMETIMES ASSOCIATED WITH XYLEM TISSUE,ARE STRONG AND FLEXIBLE AND CONTRIBUTE MAINLY TO STEM FIBRES
2. COTTON FIBRESIS OBTAINED FROM SOFT FLUFFY FRUIT OF PLANT OF COTTON.
3. Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose.
4. West Bengal is the largest producer of jute in India. India is the largest producer of jute in the world. Approximately 60 percent of the total world produce of jute is cultivated in India with an annual estimated production of 11494 thousand bales of jute.
