Answer 1

Xerophytes can withstand a prolonged period of drought, for this purpose they have certain peculiar adaptations. Thick cuticle is present in these plants. Stomata are generally sunken (deep seated) and open during night only. They have CAM pathway for photosynthesis. Leaves are generally small and scaly. Sometimes leaves are modified into spines to reduce water loss through transpiration.They generally have an extensive root system and a smaller shoot system.Stems may be modified to phylloclades or dadoes to carry out the function of photosynthesis.
