Why are salt flats hostile to plants Why are salt flats host

Solution

Salt flats are deserts and gets hardly any rain to sustain plant growth. Small plants can only sustain during rainy days and when water depletes and surface becomes dry only few xerophytes (desert adapted plants) those root deep to collect underground water survives. Xerophytes also have special adaptive changes like reduced transpiration, water resistant cuticles, conversion of leaves to spines/thorns (chlorophylls and photosynthesis displaced to trunks) , succulent leaves, and secretes salt crystals. Salt flats are also hostile to plants as high concentration salt and mineral dehydrate cells and kills plants and even bacteria. The common example of xerophytes are cactus.
