Which plant tissue primarily makes up the veins of a leaf?

• A. Dermal tissue (epidermis)
• B. Meristematic tissue (apical meristem)
• C. Ground tissue (mesophyll parenchyma)
• D. Vascular tissue (xylem and phloem)

Answer: (D)

Verified step by step guidance

1. Understand the main types of plant tissues: dermal, ground, meristematic, and vascular tissues.
2. Recall that dermal tissue (epidermis) forms the outer protective layer of the leaf, not the veins.
3. Recognize that meristematic tissue (apical meristem) is responsible for growth and is not part of the leaf veins.
4. Know that ground tissue (mesophyll parenchyma) is involved in photosynthesis and storage, making up most of the leaf interior but not the veins.
5. Identify vascular tissue, which includes xylem and phloem, as the tissue that forms the veins of the leaf, responsible for transport of water, nutrients, and sugars.
