In monocotyledonous stem

Options

A. Epidermis is covered with a thick cuticle and bears a few stomata.
B. The cells of hypodermis are collenchymatous.
C. Ground tissue consists of rounded parenchymatous cells without intercellular spaces
D. The vascular bundles are many in number and are of same size.

Explanation

### Step-by-Step Solution:

1. **Understanding the Structure of Monocotyledonous Stem**:
- The monocot stem has a specific arrangement of tissues. The outermost layer is the epidermis, which is covered with a thick cuticle to prevent water loss.

**Hint**: Remember that the epidermis serves as a protective layer in plants.

2. **Epidermis and Stomata**:
- The epidermis contains stomata, which are small openings that facilitate gas exchange (CO2 and O2) and transpiration (loss of water vapor).

**Hint**: Think about the role of stomata in plant respiration and water regulation.

3. **Hypodermis Composition**:
- Beneath the epidermis is the hypodermis, which is primarily composed of sclerenchyma tissue. Sclerenchyma provides mechanical support and is made up of dead cells.

**Hint**: Sclerenchyma is known for its strength; consider what types of cells contribute to this property.

4. **Ground Tissue Characteristics**:
- The ground tissue in monocot stems consists of parenchymatous cells. These cells typically have intracellular spaces, which are important for storage and metabolic functions.

**Hint**: Parenchyma cells are versatile; think about their roles in storage and tissue repair.

5. **Vascular Bundles**:
- Monocot stems have numerous vascular bundles that are scattered throughout the ground tissue. Unlike dicots, these bundles are usually of different sizes and are not arranged in a ring.

**Hint**: Visualize the arrangement of vascular bundles in monocots compared to dicots.

6. **Evaluating Statements**:
- Based on the above information, we can evaluate the statements provided:
- The first statement about the epidermis and stomata is correct.
- The second statement about hypodermis being composed of collenchyma is incorrect; it is made of sclerenchyma.
- The third statement about ground tissue lacking intracellular spaces is incorrect; it does have them.
- The fourth statement about vascular bundles being of the same size is also incorrect; they are of different sizes.

**Hint**: Always cross-reference statements with your understanding of plant anatomy.

7. **Conclusion**:
- The only correct statement regarding the monocotyledonous stem is the first one about the epidermis and stomata. The other statements are incorrect based on the structural characteristics of monocot stems.

**Hint**: Summarize the key features of monocot stems to reinforce your understanding.
