Why do parts of plants undergo modifications?

Certain parts of a plant undergo modification in order to adapt to their surroundings and environmental conditions. These modifications help them in their survival against odds. For example, the leaves in a cactus plant are modified to spines to reduce the surface area and hence water loss by evaporation. This saves the cactus plant in deserts from dying where the water content is low.
