Corms can be differentiated from rhizome in having

Options

A. less conspicous buds
B. oblique growth
C. perennial life
D. circular nodes

Answer

To differentiate corms from rhizomes, we need to examine their structural and functional characteristics. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Definition of Corms and Rhizomes**:
- Corms are short, thick, and underground storage organs that serve as a means of vegetative reproduction.
- Rhizomes are elongated, horizontal underground stems that also serve for vegetative reproduction but have a different structure and growth pattern.

2. **Structure**:
- Corms are generally **short and thick**. They are compact and have a bulbous shape.
- Rhizomes are **elongated and stumpy**, which means they can grow horizontally and can be branched.

3. **Condensation**:
- Corms are **highly condensed** structures, which means they have a compact form.
- Rhizomes are **rarely condensed** and can be more elongated.

4. **Branching**:
- Corms are typically **unbranched**, meaning they do not produce side shoots.
- Rhizomes are **branched**, allowing them to spread out and form new plants.

5. **Orientation**:
- Corms usually grow in a **vertical orientation**.
- Rhizomes grow in a **horizontal or oblique orientation**.

6. **Nodes**:
- Corms have **circular nodes**. This is a distinguishing feature of corms.
- Rhizomes do not have circular nodes.

7. **Buds**:
- Corms possess **conspicuous buds** that are easily visible.
- Rhizomes have **less conspicuous buds** that are not as easily seen.

8. **Lifespan**:
- Corms typically have a **short lifespan**, lasting about 1 to 3 years.
- Rhizomes can be **perennial**, surviving for several years.

### Conclusion:
Based on the characteristics discussed, the correct differentiation is that corms can be identified by having **circular nodes**, which is a unique feature compared to rhizomes.
