A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.
A xerophile (from Greek ξηρός : xērós 'dry' and φίλος : phílos 'loving') [1] is an extremophilic organism that can grow and reproduce in conditions with a low availability of water, also known as water activity. Water activity, a thermodynamical value denoted aw, is defined as the partial water vapor pressure p in equilibrium with ...
Drought tolerance. In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [1][2][3] Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. [3]
The pineapple is an example of a CAM plant. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night. In a plant using full CAM, the stomata in the leaves ...
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. [1] Deserts and xeric (Ancient Greek ξηρός xērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth 's land surface area. [2] Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less ...
The species is a xerophyte, a drought-tolerant plant and survives in environments with sustained predictable dry periods followed by periods of moist soil. Frankenia pauciflora can subsist in a range of soil pHs ranging from acidic to alkaline. In addition, the plant tolerates hot overhead sun to warm low sun and is characterized as is shade ...
As a xerophyte (drought-resistant species), carob is well adapted to the conditions of the Mediterranean region with just 250 to 500 millimetres (10 to 20 in) of rainfall per year. [19] Carob trees can survive long periods of drought, but to grow fruit, they need 500 to 550 millimetres (20 to 22 in) of rainfall per year. [19]
Xerocole. The fennec fox 's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1] A xerocole (from Greek xēros / ˈzɪroʊs / 'dry' and Latin col (ere) 'to inhabit'), [2][3][4] is a general term referring to any animal that is adapted to live in a desert.
