Some plant adaptations to low water supply Greater root/shoot ratio (increases the surface area of roots and decrease the surface area of leaves through which water is lost) Drop leaves entirely during the dry season (deciduous trees in dry tropical forests or complete the life cycle entirely in brief wet periods (desert annuals) Store water (like a cactus) for use during the dry season Expose less surface area to sun, which reduces heating Waxy coatings and trichomes that prevent evaporative water loss Have sunken stomatal chambers to reduce water loss when stomates are open.
