Collenchyma tissue is present in
Or
Collenchymatous hypodermis is characteristics of

Options

A. Dicot stem
B. Monocot stem
C. Monocoat as well as dicot stem
D. Hydrophytes

Answer

**Step-by-Step Solution:**

1. **Understanding Collenchyma Tissue:**
- Collenchyma is a type of plant tissue that provides support and flexibility, particularly in young stems and leaves. It consists of living cells that have unevenly thickened cell walls.

2. **Identifying the Location of Collenchyma:**
- Collenchyma tissue is primarily found in the hypodermis (the layer just beneath the epidermis) of stems and petioles in dicotyledonous plants (dicots).

3. **Characteristics of Dicot Stem:**
- In dicot stems, the hypodermis is composed of collenchyma cells which have angular thickenings. These cells are closely packed with minimal intercellular spaces, providing mechanical support and protection.

4. **Comparing with Monocot Stem:**
- In monocotyledonous plants (monocots), the hypodermis is typically made up of sclerenchyma cells instead of collenchyma. Sclerenchyma provides rigidity and strength but does not have the same flexibility as collenchyma.

5. **Evaluating Other Options:**
- In hydrophytes (aquatic plants), the hypodermis is poorly developed and does not consist of collenchyma tissue. Therefore, it is not characteristic of these plants.

6. **Conclusion:**
- Based on the characteristics of collenchyma tissue and its location, the correct answer is that collenchyma tissue is present in dicot stems, and collenchymatous hypodermis is a characteristic of dicot stems.

**Final Answer:**
Collenchyma tissue is present in dicot stem, and collenchymatous hypodermis is characteristic of dicot stem.
