Epidermis of axis/stem of Funaria shows

Options

A. Absence of cuticle
B. Absence of stomata
C. Absence of cuticle but absence of stomata
D. Both A and B.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the characteristics of the epidermis of the stem (axis) of Funaria, which is a type of moss.

2. **Defining Epidermis:**
The epidermis is the outermost layer of cells in plants. In the case of Funaria, this layer is important for understanding its adaptations.

3. **Characteristics of Funaria's Epidermis:**
- The cells in the epidermis of Funaria are tangentially elongated. This means that the cells are stretched out in a direction parallel to the surface of the stem.
- A key characteristic of the epidermis of Funaria is that it lacks stomata. Stomata are small openings that allow for gas exchange, and their absence is significant for the plant's adaptation to its environment.
- Additionally, the cuticle, which is a waxy layer that helps reduce water loss, is also absent in Funaria.

4. **Classification of Funaria:**
Due to the absence of stomata and cuticle, Funaria is classified as a myxohydric moss. This classification indicates that it has specific adaptations to retain moisture in its environment.

5. **Evaluating the Options:**
- Option A: Absence of cuticle - This is correct.
- Option B: Absence of stomata - This is also correct.
- Option C: Absence of cuticle but presence of stomata - This is incorrect.
- Therefore, the correct answer is option D, which states that both A and B are correct.

**Final Answer:**
The epidermis of the axis/stem of Funaria shows the absence of stomata and the absence of cuticle. Thus, the correct option is D (both A and B).
