What is incorrect about the pteridophyta ?

Options

A. Wall differentiated with. Vascular tissue
B. Small and undifferentiated
C. Gametophytic phase
D. free living

Answer

To determine what is incorrect about the pteridophyta, we will analyze the characteristics of pteridophytes based on the options provided.

### Step-by-Step Solution:

1. **Understanding Pteridophytes**:
- Pteridophytes are the first terrestrial vascular plants. They are classified under the group known as cryptogams, which means they do not produce flowers or seeds.

2. **Analyzing the Options**:
- **Option 1: Well differentiated with vascular tissue**:
- Pteridophytes have a well-differentiated structure comprising roots, stems, and leaves. They possess vascular tissues (xylem and phloem) for the conduction of water and nutrients. This statement is **correct**.

- **Option 2: Small and undifferentiated**:
- This statement suggests that pteridophytes are small and lack differentiation. However, pteridophytes are well-differentiated into roots, stems, and leaves. Therefore, this statement is **incorrect**.

- **Option 3: Gametophytic phase**:
- Pteridophytes exhibit an alternation of generations, which includes a gametophytic phase (haploid) and a sporophytic phase (diploid). This statement is **correct**.

- **Option 4: Free living**:
- The sporophyte phase of pteridophytes is free-living, meaning it can exist independently. This statement is also **correct**.

3. **Conclusion**:
- The only incorrect statement about pteridophytes is that they are "small and undifferentiated." Therefore, the answer to the question is **Option 2**.
