Explanation:

Psammophytes are plants that grow in sandy soils or desert environments where water retention is low.

They have adaptations like deep roots, small leaves, and waxy coatings to survive in dry, shifting sands.

Examples: Beach grasses, sand dune plants (e.g., Spinifex, Marram grass).

Other Options:

Chasmophytes → Grow in rock crevices.

Oxylophytes → Grow in acidic soils.

Lithophytes → Grow on rocks (like mosses, lichens, and orchids).
