Life Cycle of The Silkworm IELTS writing Task 1
You should spend about 20 minutes on this task.
The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Model Answer 1: Life Cycle of The Silkworm IELTS
The diagram delineates the life cycle of silkworms and phases in manufacturing silk cloth.
Overall, the life cycle of the silkworm consists of four stages that begin with the eggs from a mother worm, and end on the cocoon phase. Likewise, silk production from worms has four main steps – commencing with boiling selected cocoons into waters and ending in the dying process.
First of all, the life cycle of silkworms is initiated by the laying of eggs by the mother worms, and it usually takes 10 days to produce larva. Then the silkworm larva uses mulberry leaves as food. After 4 to 6 weeks, silk thread formation starts and consequently they produce larvae. Cocoons are the end product of silk thread made by larvae that develop within 3 to 8 days.
To produce silk cloth, selected cocoons are put in the boiling water in a container. Next, the larva undergoes unwinding for the development of approximately 300-900 length silk thread. Eventually, adding dye into the thread goes under the process of twisting. Finally, the weave is ready for the dying process, and that is the final step of silk cloth production.
Model 2: Life Cycle of The Silkworm IELTS
The first diagram represents the stages and times required for the silkworm’s lifecycle, and the second diagram presents the making process of silk cloth.
Generally speaking, the life cycle of silkworms begins with lying eggs on a mulberry leaf by a moth. It takes approximately two months to complete the whole process. Also, the production of silk cloth requires five main steps to finish the procedures.
As we can be seen, the first step of the evolution of silkworms is laying eggs on a leaf by the mother and these eggs take ten days to become larvae. These larvae eat mulberry leaf as their food which is the second step. After these two steps, these larvae are enclosed by silk thread within four to six weeks and transform into a cocoon in between three to eight days. Lastly, the cocoon takes around 16 days to become a moth.
It is noticeable from the production of the silk cloth diagram that the very first step is selecting the cocoon. In the second step, these are then boiled in hot water. After boiling the cocoon, they become threads of 300-900 meters long, and this stage is called the unwind. The next step is the twist in which threads are twisted, and finally, the last process of making silk cloth involves weaving. After weaving these threads, they are ready for drying if it is necessary.
Model:3
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 into 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 a 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 colored with the help of dye.
Model 4
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 silk production comprises 5 stages.
According to the first diagram, the life cycle of the silkworm begins from the ‘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.
