The correct answer is option 'B' - (B) Green fleshy stem.
Explanation:
Pine trees have several structural adaptations that allow them to survive in hilly areas, but the most relevant one is the green fleshy stem. Let's discuss the reasons why this adaptation is important for their survival in hilly areas:
1. Stability: The green fleshy stem of a pine tree helps to provide stability in hilly areas. The fleshy stem is flexible and can bend without breaking in response to strong winds or uneven terrain. This allows the tree to remain firmly rooted in the ground, even on steep slopes.
2. Water storage: The green fleshy stem of a pine tree acts as a reservoir for storing water. In hilly areas, water tends to drain quickly from the soil due to the slopes, making it challenging for plants to access sufficient water. The green fleshy stem helps the pine tree to store water during rainy periods, which can be used during dry spells when water is scarce.
3. Photosynthesis: The green color of the fleshy stem indicates the presence of chlorophyll, which is the pigment responsible for photosynthesis. Photosynthesis is the process by which plants convert sunlight into energy to fuel their growth. In hilly areas, sunlight may be limited due to the presence of taller trees or the orientation of the slopes. By having a green fleshy stem, pine trees can perform photosynthesis even in shaded conditions, allowing them to survive in areas with reduced sunlight.
4. Nutrient uptake: The fleshy stem of a pine tree also plays a role in nutrient uptake from the soil. Hilly areas often have shallow, rocky soils that are low in nutrients. The green fleshy stem helps the tree to absorb nutrients directly from the soil, bypassing the need for extensive root systems that may be hindered by rocks or steep terrain.
Overall, the green fleshy stem of a pine tree is a crucial structural adaptation that enables its survival in hilly areas. It provides stability, water storage, the ability to perform photosynthesis in shaded conditions, and efficient nutrient uptake from the soil. These adaptations help the pine tree to thrive in challenging environments and successfully colonize hilly areas.

Needle-like leaves and cones instead of flowers are structural adaptation which allow the pine tree to survive in hilly areas.
