AWell developed root systems
BThick waxy leaf cuticles
CWind dispersed light seeds
DVery deep taproots for water
Answer & Solution
Correct answer: A. Well developed root systems
1. Savannas have a long dry season and fire is a regular disturbance there.
2. Fire destroys the parts of a plant that stand above the ground.
3. Plants with well developed root systems keep living tissue safely below the surface.
4. From those roots they can re-sprout quickly once the fire has passed.
5. A waxy cuticle slows water loss but gives no protection against burning.
