Synthetic fibres have the following disadvantages.
- Most fabrics made from synthetic fibres require careful ironing as they melt easily.
- Most fabrics made from synthetic fibres absorb very little moisture. They become sticky when the body sweats, which makes them uncomfortable to wear in hot weather.
- Most fabrics made from synthetic fibres catch fire very easily. Therefore, it is dangerous to wear them near a source of fire (e.g., while working in the kitchen).

Federalism: This refers to the existence of more than one level of government in the country. In India, we have governments at the state level and at the centre. Panchayati Raj is the third tier of government. While each state in India enjoys autonomy in exercising powers on certain issues, subjects of national concern require that all of these states follow the laws of the central government. Under federalism, the states are not merely agents of the federal government but draw their authority from the Constitution as well. All persons in India are governed by laws and policies made by each of these levels of government.

Undesirable plants that grow along with crop plants are known as weeds. Xanthium, Parthenium, etc. are some common weeds. Weeds compete with the crop for nutrients, light, and space. As a result, crop plants get lesser nutrients, light, and space for their development. This in turn, reduces their productivity. Thus, various weeding methods are employed.
Some important weeding methods are:
- Weeds can be controlled using weedicides. It is a chemical, which is sprayed in the fields to kill all available weeds. Weedicides are not harmful to crops.
- Tilling before sowing of crops also helps in removing weeds. Tilling uproots the weeds. The best time for the removal of weeds is before they produce flowers and seeds.
- The manual method of removing weeds is with the help of a khurpi. It involves regular uprooting or cutting of weeds close to the ground.
