Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Fibrous Roots**: Fibrous roots are characterized by their thin and moderately branching structure, which forms a net-like appearance. 2. **Origin of Fibrous Roots**: Unlike tap roots that originate from the radical region (the embryonic root), fibrous roots originate from the base of the stem. This is a key distinguishing feature of fibrous roots. 3. **Occurrence in Plants**: Fibrous roots are typically found in monocotyledonous plants (monocots) and certain ferns. Monocots include plants such as cereals like wheat and rice. 4. **Visual Representation**: To visualize, the fibrous roots emerge from the base of the stem, creating a network of roots that spread out in the soil. 5. **Conclusion**: In summary, fibrous roots originate from the base of the stem and are primarily found in monocotyledonous plants and some ferns. ---
