The life cycle of the silkworm

Stages in the production of silk cloth

Sample Answer 1:
The given pictorial show the life cycle of the silkworm and also shows the processes of silk cloth productions.

The life cycle of a silkworm begins from the eggs laid by the mother worm and from these eggs the silkworm larvae are generated after 10 days. The silkworm larva usually eats leaves like mulberry leaves and completes the second stage of the life cycle in 4-6 weeks. In their third stage, they create silk thread shells and remain there for another 3 to 8 days and then create an oval cocoon. The cocoon stage lasts for around 16 days and they become moth in the final stage. With time the moths become grown-up and recycle the processes again.

The second picture describes the processes of the silk cloth production which have more than 5 stages. In the initial stage, the silk thread shells of the silkworm are selected and then boiled in the next stage. After boiling in water the threads are unwinded and they are usually 300 to 900 meter long. Then these are twisted and dyed and finally, those are weaved to silks. The twisting, dying, weaving and then dying again the process is done more than once as per necessary to produce fine quality silks.


Sample Answer 2:
The two given pictures describe the life cycle of silkworm and also illustrate the procedure of silk cloth production.

As is presented in the first picture life cycle of silkworm begins with eggs laid by mother worm. Silkworm eggs transform into the shape of silkworm larva after around 10 days. Then the second process starts, and in this stage larva usually, eat leaves like mulberry leaves in order to grow up.

Food process lasts 4 to 6 weeks. Larva generates silk threads shells at the end of the second stage. The third stage begins when silk thread shells create cocoons, this process usually lasts for 3 to 8 days. In the final stage, cocoons transform into moths after 16 days. And moths grow up and recycle whole procedure step by step.

As is observed from the second picture, which describes the producing of silk cloth from silkworm, total stages of silk cloth production are five. Initially, in the first stage, silk thread shells are selected and boiled into hot water. Shells are unwinded properly and unwinded shells are exactly 300 to 900m long. Then threads are twisted and dyed in dyers. And finally, those silks are weaved and again dyed.

The process of twist and dry, weave and dry possibly repeated if it is necessary to produce high-quality silk cloth.

Model Answer 3:
The diagrams illustrate the life cycle process of the silkworm as well as various steps in making of silk cloth.

Overall, the life cycle of silkworm has four major stages which begin with eggs and end with cocoon. Similarly, there are four main steps in the production of silk cloth commencing with boiling into the water and ending with dying process.

Initially, the life cycle of silkworms starts with eggs which are laid by bees on the mulberry leaves. After this stage of the cycle, it becomes silkworm larva on mulberry leaves. It is then developed into silk thread within 4 to 6 weeks. After the last main stage of the life cycle, it is transformed into cocoons, which is necessary to make a silk cloth.

In the production of silk cloths, selected cocoons are boiled into the water. Unwinding is in the second process in which 300 to 900 mm threads are produced. Eventually, it is then twisted which is helpful for making waves. Finally, the wave is ready for dye process in any colour for the final production of silk clothes.

The diagram shows different stages in the production of silk cloth which starts from laying eggs and takes around 70 days. The life cycle of the silkworm takes around 70 days to complete.

Firstly, the lifecycle of the silkworm begins with laying the eggs which take 10 days to become a larva. The mulberry leaf is the source of food for the larva in this stage. Furthermore, it takes around 4-6 weeks for the larva to form a silk thread in its outer coating. Then within the next 3-8 days, it changes into a cocoon, which later transforms to a moth, which again gives the eggs and the complete process is repeated.

Lastly, In the production stage, only three steps are followed to make silk cloth. It starts by selecting cocoon, which is then boiled in hot water. After completing, the cocoon is unwinded and a 300-900m thread is formed. Finally, it is twisted and weaved and later coloured with the help of dye.

Thank a lot.
I'm impressed with the way of this explanation.

Wrong explanation, it covers itself with silk thread and knows as the cocoon. After that cocoon hatched and the moth is released, and it lay eggs again to start the cycle.

The illustration outlines the life cycle of a silkworm and the process of silk thread production.

In general, the life cycle of the silkworm has four stages - starting with the egg stage and ending with becoming moths. Similarly, the production of silk thread has different steps, which initiates with the selection of the silk threads and finishes with dying the yarn.

Based on the illustration, the life cycle of the silkworm goes through many strides. In the first step, eggs are laid by butterflies. After ten days, silkworm larva gets out of the eggs and eat the mulberry leaf. 4 to 6 weeks later, the caterpillar transforms to silk thread. Then, after another 3-8 days, the cocoon is turned to months which later on contribute to laying eggs to reiterate the life cycle.

Again, the production of silk has six stages. First, the cocoons are chosen. Then, the cocoon is placed in water for boiling. After that, the cocoon is unwinded to give a thread of about 300-900 metre. In the next step, the thread is dyed and weaved. This process is used to produce the silk thread.

Well done, you wrote well.

It's really good to come to know about the way of writing. I also use this website and I got 7 bands in my final test.

The two given diagrams illustrate the life cycle of silkworms and show the processes of silk production.

Overall the life cycle of a silkworm is completed in 4 stages, in around 10 to 11 weeks, while the silk production comprises 5 stages.

According to the first diagram, the life cycle of silkworm begins from 'laying eggs' stage and after 10 days, these eggs produce larvas. During this stage, larvas basically eat the mulberry leaf. After 4 to 6 weeks, these larvas are transformed into silk thread and then silk threads to cocoon after 3-8 days. Cocoons change into the moth in 16 days and then lay eggs to reiterate the circle.

The second picture shows how the production of silk takes place. Initially, silk threads are selected and then boiled in the water. After boiling, the threads are unwinded up to 300-900 meter long thread. Later they are twisted and dyed accordingly. They are prepared for weaving and are dyed again.

It helped me a lot... Thank you.

I'm so pleased to have the chance to find your site with the help of my IELTS instructor. I've just started my IELTS course and I sometimes find it too challenging to write task 1. I have problems understanding where to begin my cycles and processes. I need your help. I am also in need of someone who could give me a hand in correcting the essay I have written. Yours,Roya Ataee.

It would be "dyed".
Very very very useful information. I was able to know a lot of information from this website. Thanks to whoever has written this and it is really helpful for my science projects.
The plural of "leaf" is "leaves".

Hi,It's a very helpful website.I am a bit confused about the last stage of silk production - after weaving, the threads are dyed or dried.
Dyed should be used and it means coloured.

Thanks K for your comment. Actually, we have already started the process. Hopefully, the review would be completed quite soon. Thanks again for visiting our website.
An administrator is needed for this website to check and correct the essays posted. They have a lot of grammatical mistakes, I have never seen this on any other website with a similar context. Students-to-be are reading your sample answers, please make sure they are error-free.
'Pictorial' is an adjective, not a noun. You can't say "the given pictorials". It's used like - a pictorial encyclopaedia.
Dyer for giving colour, not for drying, here it is written as dried in dryer...
This website is a great help for IELTS students.
Duc Dung
Plural form of "larva" is "larvae".
Generally, I do not read posts on blogs, but I would like to say that is a really good website I found for my IELTS Preparation.
