Answer

To answer the question "Roots are adventitious depending on their", we need to understand the concept of adventitious roots and their characteristics. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Definition of Adventitious Roots**: Adventitious roots are roots that arise from parts of the plant other than the root system, such as stems or leaves. This is in contrast to primary roots that develop from the radicle of the seed.

2. **Origin of Adventitious Roots**: The key characteristic of adventitious roots is their origin. They do not originate from the root part of the plant. Instead, they can emerge from the stem or leaves.

3. **Examples of Adventitious Roots**: Common examples include the roots of plants like corn (Zea mays) and banyan trees (Ficus benghalensis), where roots develop from the stem.

4. **Significance of Adventitious Roots**: These roots can serve various functions, including providing additional support, helping in nutrient absorption, and facilitating vegetative propagation.

5. **Conclusion**: Therefore, adventitious roots are classified based on their origin, specifically where they arise from in the plant structure.
