Hypodermis is _____in sunflower stem and ______in maize stem

Options

A. parenchymatous, collenchymatous
B. collenchymatous, sclerenchymatous
C. sclerenchymatous, collenchymatous
D. sclerenchymatous, parenchymatous

Explanation

To answer the question regarding the nature of the hypodermis in sunflower and maize stems, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Plant Tissues**:
- Plant tissues are classified into two main categories: meristematic tissues (which are capable of division) and permanent tissues (which are differentiated and do not divide).
- Permanent tissues can be further divided into simple permanent tissues (such as parenchyma, collenchyma, and sclerenchyma) and complex permanent tissues.

2. **Identify the Hypodermis**:
- The hypodermis is the layer of tissue located just beneath the epidermis in plant stems. It provides support and protection.

3. **Determine the Type of Hypodermis in Sunflower Stem**:
- In the sunflower stem, the hypodermis is primarily composed of **collenchyma** tissue. This type of tissue is characterized by its ability to provide flexible support while allowing for growth.

4. **Determine the Type of Hypodermis in Maize Stem**:
- In the maize stem, the hypodermis is primarily composed of **sclerenchyma** tissue. Sclerenchyma is known for providing rigid support due to its thick cell walls.

5. **Conclude the Answer**:
- Therefore, the hypodermis is **collenchymatous** in the sunflower stem and **sclerenchymatous** in the maize stem.

### Final Answer:
The hypodermis is **collenchymatous** in sunflower stem and **sclerenchymatous** in maize stem.
