Root is distinguishable from stem in

Options

A. Having a root cap
B. having root halls
C. Absence of nodes and internodes
D. All of the above

Answer

To answer the question "Root is distinguishable from stem in," we need to identify the key differences between roots and stems. Here’s a step-by-step breakdown:

### Step 1: Identify the Structure of Roots
Roots have a specialized structure known as the **root cap**. This cap protects the growing tip of the root as it pushes through the soil.

### Step 2: Identify the Structure of Stems
In contrast, stems do not have a root cap. Instead, they have **nodes** and **internodes**. Nodes are points on the stem where leaves or branches arise, while internodes are the segments between two nodes.

### Step 3: Compare the Presence of Nodes and Internodes
Roots do not have nodes and internodes. This is a significant distinguishing feature, as stems are characterized by the presence of these structures.

### Step 4: Summarize the Key Differences
1. **Root Cap**: Present in roots, absent in stems.
2. **Nodes and Internodes**: Present in stems, absent in roots.

### Conclusion
Based on the above points, we can conclude that roots are distinguishable from stems primarily due to the presence of a root cap in roots and the presence of nodes and internodes in stems.

### Final Answer
Roots are distinguishable from stems in that they have a root cap, while stems have nodes and internodes.
