Lacunar collenchyma is specifically present in hypodermis of

Options

A. (a) Cucurbita stem
B. (b) Sunflower stem
C. (c) Brinjal stem
D. (d) None of The Above

Answer

To answer the question "Lacunar collenchyma is specifically present in hypodermis of?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Collenchyma**:
- Collenchyma is a type of plant tissue that provides support and flexibility to young stems and leaves. It is characterized by unevenly thickened cell walls.

2. **Types of Collenchyma**:
- There are three types of collenchyma:
- **Lamellar Collenchyma**: Found in layers, primarily in the sunflower stem.
- **Angular Collenchyma**: Found at the angles of cells, primarily in the brinjal stem.
- **Lacunar Collenchyma**: Characterized by intercellular spaces, primarily found in the Cucurbita stem.

3. **Identifying Lacunar Collenchyma**:
- Lacunar collenchyma is specifically noted for its distinct intercellular spaces and the deposition of pectocellulose in these spaces.

4. **Location of Lacunar Collenchyma**:
- The question asks where lacunar collenchyma is specifically present in the hypodermis. The hypodermis is a layer beneath the epidermis in plant stems.

5. **Finding the Correct Example**:
- Among the examples provided:
- A) Sunflower stem - contains lamellar collenchyma.
- B) Brinjal stem - contains angular collenchyma.
- C) Cucurbita stem - contains lacunar collenchyma.
- D) None of the above.
- The correct answer is **C) Cucurbita stem**, as it is the only option where lacunar collenchyma is specifically present in the hypodermis.

### Final Answer:
Lacunar collenchyma is specifically present in the hypodermis of **Cucurbita stem**.
