Show Hint
Dermal = Skin (Epidermis, Periderm).
Vascular = Veins (Xylem, Phloem).
Ground = Everything else (Cortex, Pith, Mesophyll).

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question requires the classification of plant tissues into their respective tissue systems. Specifically, it asks to identify which of the given options belongs to the dermal tissue system.
Detailed Explanation:
• Plant Tissue Systems:
Julius von Sachs classified plant tissues into three main systems based on their function and location:
1. Dermal Tissue System: The outer protective covering of the plant.
2. Ground (Fundamental) Tissue System: Tissues that are neither dermal nor vascular, involved in photosynthesis, storage, and support.
3. Vascular Tissue System: Tissues involved in the long-distance transport of water and nutrients.
• Epidermis:
The epidermis is the primary component of the dermal tissue system in a non-woody plant.
It is usually a single layer of cells covering the entire plant body, including leaves, stems, and roots.
It often includes specialized cells like guard cells (in stomata) and root hairs.
• Analyzing other options:
Xylem and Phloem: These are the complex tissues that make up the Vascular Tissue System.
Ground tissue: This is a separate system containing parenchyma, collenchyma, and sclerenchyma.
Step 2: Final Answer:
Epidermis is the characteristic tissue of the dermal tissue system.
