The vascular tissue is absent in :-

Options

A. Algae, fungi and pteridophytes
B. Thallophytes and bryophytes
C. Bryophytes and pteridophytes
D. Angiosperm and gymnosperm

Answer

To determine where vascular tissue is absent, we need to understand what vascular tissues are and which groups of plants possess or lack them.

### Step-by-Step Solution:

1. **Define Vascular Tissue**:
- Vascular tissues are specialized tissues in plants responsible for the conduction of water and nutrients. There are two main types: xylem (for water transport) and phloem (for food transport).

2. **Identify Groups of Plants**:
- The main groups of plants include:
- Algae (Thallophytes)
- Fungi (not classified as plants but often included in discussions)
- Bryophytes (mosses and liverworts)
- Pteridophytes (ferns)
- Gymnosperms (conifers)
- Angiosperms (flowering plants)

3. **Analyze Each Option**:
- **Option A: Algae, fungi, and pteridophytes**:
- Algae (thallophytes) lack vascular tissues, but pteridophytes do have vascular tissues. This option is incorrect.
- **Option B: Thallophytes and bryophytes**:
- Thallophytes (including algae) do not have vascular tissues, and bryophytes also lack true vascular tissues. This option is correct.
- **Option C: Bryophytes and pteridophytes**:
- Bryophytes lack vascular tissues, but pteridophytes have them. This option is incorrect.
- **Option D: Angiosperms and gymnosperms**:
- Both angiosperms and gymnosperms possess vascular tissues. This option is incorrect.

4. **Conclusion**:
- The only option where vascular tissue is absent is **Option B: Thallophytes and bryophytes**.

### Final Answer:
The vascular tissue is absent in **Thallophytes and Bryophytes**.
