Select the pair of fibres obtained from the stem of a plant :

Question

Accepted Answer

Option 2, which is "Flax and Jute," is the correct answer because both flax and jute are fibers obtained from the stem of plants. Let's delve into the details:

1. **Flax**: Flax fibers are derived from the stem of the flax plant (Linum usitatissimum). The process of extracting these fibers involves retting, which is the rotting of the plant stems to separate the fibers from the rest of the plant material. Flax fibers are known for their strength and are commonly used to make linen.

2. **Jute**: Jute fibers are also obtained from the stem of the jute plant (Corchorus species). Similar to flax, the extraction process involves retting. Jute is a long, soft, and shiny vegetable fiber that can be spun into coarse, strong threads. It is widely used for making burlap, hessian, and other products.

Now, let's explain why the other options are incorrect:

1. **Option 1: Coir and Flax** - Coir is not obtained from the stem of a plant. Instead, it is a natural fiber extracted from the husk of coconuts. Therefore, this option is incorrect because coir is not a stem fiber.

2. **Option 3: Jute and Kapok** - While jute is a stem fiber, kapok is not. Kapok fibers come from the seed pods of the kapok tree (Ceiba pentandra). The fibers are fluffy and lightweight, often used as stuffing material. Since kapok is not a stem fiber, this option is incorrect.

3. **Option 4: Kapok and Hemp** - As mentioned, kapok is not a stem fiber. Hemp, on the other hand, is a stem fiber obtained from the Cannabis sativa plant. However, since kapok is not a stem fiber, this option is incorrect.

In conclusion, Option 2 is the only pair where both fibers, flax and jute, are obtained from the stem of plants, making it the correct choice.
