A xerophyte or xerophytic organism (xero meaning dry, phyte meaning plant) is a plant which is able to survive in an environment with little available water or moisture, usually in environments where potential evapotranspiration exceeds precipitation for all or part of the growing season. Plants like the cacti and other succulents are typically found in deserts where low rainfall amounts are the norm, but xerophytes such as the bromeliads can also be found in moist habitats such as tropical forests, exploiting niches where water supplies are limited or too intermittent for mesophytic plants. Plants that live under arctic conditions may also have a need for xerophytic adaptations, as water is unavailable for uptake when the ground is frozen. Their leaves are covered with silvery hairs (creates wind break & light reflective surface).

Ok with @Pradheep xerophytic plants live in desertic areas like the cactus opuntia.

Xerophytes are plants which live in desert regions. They store water in their root, stem and leaves. They usually have thorns on them eg. Cactus.

Mesophytes are terrestrial plants which are adapted to neither a particularly dry nor particularly wet environment. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and Rosa multiflora.

Mesophytes make up the largest ecological group of terrestrial plants, and usually grow under moderate to hot and humid climatic regions.

Lithophytes are plants that grow in or on rocks. Plants those are well adapted to survive in or on the water logged areas. Examples: Lotus, Sea weeds, Pistia, Water lily.

Can anyone give some details of lithophytes, mesophytes, hydrophytes?

Xerophytes- dry condition.

Mesophytes- a plant needing only a moderate amount of water.

Lithophytes- a plant that grows on bare rock or stone.

Hydrophytes - a plant which grows only in or on water.
