Question

Name the tissue represented by the jute fibres used for making the ropes.

Answer 1

Hint:In dicotyledonous plants, some fibres are collected and later used in ropes, and other needed things. It is the inner bark of the tree from which ropes are made.

Complete answer
Xylem and phloem are vascular tissues that take part in the transfer of water and nutrients from soil to every part of the plant. Phloem is responsible for the transfer of sugar molecules from several photosynthetic tissues or several leaf cells. Not only sugars, several m-RNA and proteins are also transferred through phloem. In a cell phloem is of four types such as sieve cell, sieve tube, Phloem parenchyma and phloem fibre. Phloem fibre is also called bast fibre. Bark of several plants are used as bast. In monocotyledons, it is called leaf fibre. Bust fibres occur in bundles and are sealed with calcium and pectin which makes it solid in nature. Not only ropes but also many synthetic fibres, cotton, several textiles are also made from phloem fibres. For making ropes, at first the fibres are glued together and then soaked for hours. It causes about 3-4 months. The bundles of phloem fibres are mainly long (about several feet) and it is composed of cellulose fibres which are overlapped. These fibres are present in the epidermis, or in the bark surface. Most of the bast fibres are strong and commonly used in making ropes, bagging of materials,or other industrial fabrics. Nowadays, jutes are used for sacking or wrapping purposes.

Hence, Phloem fibre or Bast fibre is the correct answer.

Note:There is a technique that is maintained in making ropes by using bast fibres and it costs more time than that of others. Bast fibre is the plant fibre from collected phloem or bast surrounding the stem of certain dicotyledonous plants.
