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.
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]
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 ...
Family: Velloziaceae. Genus: Xerophyta. Juss. (1789) Xerophyta is a genus of flowering plants in the family Velloziaceae. It was named in 1789 by de Jussieu. [1][2] It is native to Africa, Madagascar, and the Arabian Peninsula. [3] Some species in this genus are poikilochlorophyllous plants.
By definition, succulent plants are drought-resistant plants in which the leaves, stem, or roots have become more than usually fleshy by the development of water-storing tissue. [5] Other sources exclude roots as in the definition "a plant with thick, fleshy and swollen stems and/or leaves, adapted to dry environments". [6]
They usually have larger, thinner leaves compared to xerophytes, sometimes with a greater number of stomata on the undersides of leaves. Because of their lack of particular xeromorphic adaptations, when they are exposed to extreme conditions they lose water rapidly, and are not tolerant of drought. Mesophytes are intermediate in water use and ...
A tropical marine climate is a tropical climate that is primarily influenced by the ocean. It is usually experienced by islands and coastal areas 10° to 20° north and south of the equator. There are two main seasons in a tropical marine climate: the wet season and the dry season. The annual rainfall is 1000 to over 1500 mm (39 to 59 inches).
The Karoo (/ kəˈruə / kə-ROO-ə; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ǃ’Aukarob "Hard veld " [2][3]) is a semi- desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined.
