Cork tissue arises from

Options

A. periderm
B. phellogen
C. phelloderm
D. phellem

Answer

**Step-by-Step Solution:**

1. **Understanding Cork Tissue**: Cork tissue is a protective tissue that forms the outer covering of stems and roots in plants. It is primarily produced by a layer of cells known as cork cambium.

2. **Identifying the Options**: The question provides four options regarding the origin of cork tissue:
- Option 1: Paraderm
- Option 2: Phallosome
- Option 3: Phalloderm
- Option 4: Phallum

3. **Analyzing Option 1 - Paraderm**: Paraderm refers to a tissue that includes cork, secondary cortex, and cork cambium. Since cork tissue arises specifically from cork cambium, this option is incorrect.

4. **Analyzing Option 2 - Phallosome**: Phallosome is another name for cork cambium. Cork cambium is responsible for the production of cork tissue through the process of cell division. Thus, this option is correct.

5. **Analyzing Option 3 - Phalloderm**: Phalloderm is known as the secondary cortex, which is not directly involved in the formation of cork tissue. Therefore, this option is incorrect.

6. **Analyzing Option 4 - Phallum**: Phallum refers to cork itself. Since the question asks for the origin of cork tissue, this option is also incorrect.

7. **Conclusion**: The correct answer to the question "Cork tissue arises from" is Option 2: Phallosome (cork cambium).
