Mango trees have evolved through the centuries in order to adapt to the current environmental conditions . Some of these adaptations are :

i.) Mango trees have roots that penetrate deep into the soil so that it can absorb as much water as possible.

ii.) Mango leaves have thick cuticles in order to prevent transpiration.

iii.) Mango trees produce true fruits in order to protect its seeds that are embedded in the center of the fleshy fruit.
