Collenchyma mainly form ______

Options

A. hypodermis
B. epidermis
C. phloem
D. inner cortex

Answer

**Step-by-Step Solution:**

1. **Understanding Collenchyma**: Collenchyma is a type of plant tissue that consists of living cells. It is known for providing support and flexibility to the plant.

2. **Characteristics of Collenchyma**: The cells of collenchyma are elongated and have irregularly thickened cell walls. This structure allows them to provide mechanical support while still being able to stretch and grow.

3. **Location of Collenchyma**: Collenchyma is primarily found in the stems and leaves of plants, particularly in herbaceous (non-woody) plants.

4. **Presence in Plant Types**: Collenchyma is mainly present in dicotyledonous (dicots) plants. In monocotyledonous (monocots) plants, collenchyma is generally absent.

5. **Specific Location**: Within the plant structure, collenchyma is mainly located in the hypodermis, which is the layer of tissue just below the epidermis (outer layer of cells).

6. **Conclusion**: Therefore, the answer to the question "Collenchyma mainly forms ______" is "hypodermis".

**Final Answer**: Hypodermis
