Which of the following plant adaptations aids grassland plants in recovering from fires?

• A. Extensive underground root systems
• B. Thick, waxy leaf cuticles
• C. Production of large, fleshy fruits
• D. Climbing vines for support

Answer: (A)

Verified step by step guidance

1. Understand the context of the problem: Grassland ecosystems are prone to periodic fires, which can destroy above-ground plant structures. Plants in these environments have evolved adaptations to survive and recover from such disturbances.
2. Analyze the options provided: Each adaptation listed serves a specific purpose for plants, but not all are directly related to fire recovery. For example, thick, waxy leaf cuticles help reduce water loss, large fleshy fruits aid in seed dispersal, and climbing vines provide structural support. These are not primarily fire recovery mechanisms.
3. Focus on the adaptation that directly aids in fire recovery: Extensive underground root systems are crucial for grassland plants because they allow the plant to regenerate after the above-ground parts are destroyed by fire. These roots store nutrients and energy, enabling rapid regrowth.
4. Relate the adaptation to the ecological role: Underground root systems are particularly effective in fire-prone environments because they are protected from the heat and damage caused by fires. This ensures the plant's survival and ability to regrow.
5. Conclude the reasoning: Based on the analysis, the adaptation that aids grassland plants in recovering from fires is 'Extensive underground root systems,' as it directly supports regrowth and survival after fire events.
