Natural fibers can be positively identified by microscopy due to their unique morphology.
Question 2
Select one:
- True
- False
Solution
Answer
True.
Natural fibers do have unique morphological characteristics that can be positively identified using microscopy. Each type of natural fiber, whether it be cotton, wool, flax, or silk, has distinct structural features such as cell shapes, sizes, and surface textures. For example:
- Cotton fibers: They appear as twisted ribbons and are characterized by their convoluted shape.
- Wool fibers: They have a scaly surface and often present a more irregular shape due to their natural growth patterns.
- Flax fibers: These fibers are generally longer and have a smoother surface, often showing a definite length-to-girth ratio.
- Silk fibers: They are smooth and have a high luster, appearing as long continuous threads.
Using microscopy allows for a detailed examination of these unique morphologies, making it possible to differentiate between various types of natural fibers conclusively. Thus, the statement is true.
