GENERAL KNOWLEDGE

Detailed explanation-1: -Desert plants are generally succulents or fleshy xerophytes. They are referred as drought resisting xerophytes, e.g. Opunits, Bryophyllum, Euphorbia, Mesembryanthemum (ice plant).

Detailed explanation-2: -Desert plants are also called xerophytes because they prevent water loss by storing water in their stems.

Detailed explanation-3: -A succulent must be able to absorb large quantities of water in short periods. Desert rains are often light and brief, and the soil dries rapidly under an intense sun. To cope with these conditions, nearly all succulents have extensive, shallow root systems.

Detailed explanation-4: -Deserts are far too dry and scorching for life to exist there. Despite the arid circumstances, just a few plants have evolved to flourish in this environment. Succulents are water-holding plants with modified stems and leaves. The spines of cacti also help to prevent excessive water loss.
