  4. Throughout the year.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The suitable climate for growing jute is a warm and wet climate, which is offered by the monsoon climate during the fall season, immediately followed by summer. Temperatures ranging from 25-30 °C and relative humidity of 70%–90% are favorable for successful cultivation. Jute requires 160-200 cm of rainfall weekly with extra needed during the sowing period. River basins or alluvial or loamy soils are best for jute cultivation. Jute cultivation in red soils may require a high dose of manure.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fibres can be classified as natural fibres and synthetic fibres.
Natural fibres are obtained from plants and animals. The examples of such fibres include cotton, jute, silk and wool.
Synthetic fibres are made from chemical substances, which are not obtained from plant or animal sources. Examples include polyester, nylon and acrylic.

Which of the following fibre is recyclable?

  1. Hemp

  2. Flax

  3. Sisal

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A, B and C are natural fibres. 


All natural fibres are easily recyclable. It is a renewable resource, the production requires little energy, $CO _2$ is used while oxygen is given back to the environment. 

They are also carbon neutral. They absorb the same amount of carbon dioxide they produce. 

During processing, they generate mainly organic wastes and leave residues that can be used to generate electricity or make ecological housing material. And, at the end of their life cycle, they are 100% biodegradable.

Hence the correct option is D.

$X$ is a thread of filament from which $Y$ is made. If prepared from plants and animals, it is known as $Z$ fibres whereas by humans it is known as $W$ fibres. Synthetic fibres are nylon, rayon, polyester, acrylic etc.
What is $Y$?

  1. Cloth

  2. Paper

  3. Pen

  4. Book
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fibre is the basic unit of raw material having suitable length, pliability, and strength for conversion into yarns and fabrics/material/cloth. 

A fibre of extreme length is a filament. Fibres can occur naturally or can be produced artificially. 

Here, X is a fibre, Y is the cloth/fabric/material. Z is the natural fibre and W is the artificial or human-made fibre.

paper/book is an example of products of natural polymer (cellulose), pen is an example of industrial product of synthetic polymer.

Therefore, option A is correct.

Linen fibre is obtained from __________.

  1. chia seeds

  2. cotton seeds

  3. flax plants

  4. cotton flowers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Linen yarn is spun from the long fibers found just behind the bark in the multi-layer stem of the flax plant. In order to retrieve the fibers from the plant, the woody stem and the inner pith, which holds the fibers together in a clump, must be rotted away. 

The cellulose fiber from the stem is spinnable and is used in the production of linen thread, cordage, and twine.

So, option C is correct.
