Select an incorrect match.

Options

A. Tracheids - Water coducion
B. Ray parenchyma - Supportive in function
C. Vessels - Water conduction
D. Xylem parenchyma - Food storge

Answer

To solve the question "Select an incorrect match," we will analyze each option provided in the video transcript to identify any inaccuracies.

### Step-by-Step Solution:

1. **Tracheids**:
- Tracheids are indeed water-conducting and mechanical supporting cells found in Gymnosperms.
- They play a crucial role in both water transport and providing structural support to the plant.
- **Conclusion**: This match is correct.

2. **Ray Parenchyma**:
- Ray parenchyma is a type of parenchyma tissue that primarily functions in storage and lateral transport of nutrients and water.
- The claim that it is essential for the survival of caterpillars is misleading, as ray parenchyma is not specifically related to caterpillar survival but rather to the overall functioning of the plant.
- **Conclusion**: This match is incorrect.

3. **Vessels**:
- Vessels are specialized structures in the xylem that are primarily responsible for the efficient transport of water and minerals from the roots to the rest of the plant.
- This description aligns with their main function.
- **Conclusion**: This match is correct.

4. **Xylem Parenchyma**:
- Xylem parenchyma cells are involved in the storage of food materials, including starch, fats, tannins, and crystals.
- The description provided is accurate.
- **Conclusion**: This match is correct.

### Final Answer:
The incorrect match is **Ray Parenchyma** being described as essential for the survival of caterpillars.
