In non-succulent Perennial have extensive root systems, roots penetrate deep into the soil and establish contact with sub-soil water. 

• Some trees have deep, extensive root systems that anchor them to hillsides. Shrubs service berry is a deep-rooted deciduous shrub or small tree that grows best in well-drained, slightly acidic, moist soil. Ground covers, Vetiver Grass.

Xerophytes employ multiple strategies to conserve water, including sunken stomata to reduce transpiration, deep root systems to access water, and a thick waxy cuticle to prevent water loss.

Ephemerals are classified as drought escaping plants because they avoid the drought period entirely by existing as dormant seeds.

Acacia arabica is xerophyte because it is seen in desert places.

Xerophytes minimize water loss by reducing the number of stomata or having them sunken. A larger number of stomata would increase transpiration, which is detrimental to a plant in a dry habitat.

Calotropis is a non-succulent xerophyte that features thick, leathery leaves covered in a white, waxy, or hairy coating to reduce water loss and reflect sunlight.

Xerophytes are made up of thick cuticles and contains parenchymal tissues. It does not contain Aerenchyma.

In many xerophytes, leaves are reduced to spines to prevent water loss. Consequently, the stem becomes green and photosynthetic (cladode or phylloclade) to perform the function of leaves.

Halophytes grow in saline environments where water uptake is difficult due to high salt concentrations, leading to physiological drought. Thus, they often develop xerophytic adaptations.
