Which leaf modification is correctly matched with its primary function?

• A. Spines — increased photosynthetic surface area
• B. Succulent leaves — protection from herbivores
• C. Tendrils — support for climbing plants
• D. Bulbs — water loss through transpiration

Answer: (C)

Verified step by step guidance

1. Understand the concept of leaf modifications: Leaf modifications are structural changes in leaves that help plants adapt to their environment or perform specific functions such as protection, support, or water storage.
2. Analyze each option provided in the problem: Spines, succulent leaves, tendrils, and bulbs. Determine their primary functions based on biological knowledge.
3. Evaluate the function of spines: Spines are modified leaves that primarily serve to protect the plant from herbivores and reduce water loss, not to increase photosynthetic surface area.
4. Evaluate the function of succulent leaves: Succulent leaves are thick and fleshy, adapted for water storage in arid environments, not for protection from herbivores.
5. Evaluate the function of tendrils and bulbs: Tendrils are modified leaves or stems that provide support for climbing plants, while bulbs are underground storage structures that help in nutrient storage and reduce water loss through transpiration. Match the correct function to tendrils as support for climbing plants.
