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.
For example, Jacobsen's three volume Handbook of Succulent Plants does not include cacti. [10] Many books covering the cultivation of these plants include "cacti (cactus) and succulents" as the title or part of the title. [11] [12] [13] In botanical terminology, cacti are succulents, [5] but not the reverse, as many succulent plants are not cacti.
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.
Ammophila (synonymous with Psamma P. Beauv.) is a genus of flowering plants consisting of two or three very similar species of grasses. The common names for these grasses include marram grass, bent grass, and beachgrass. [ 2 ] These grasses are found almost exclusively on the first line of coastal dunes. Their extensive systems of creeping ...
Mesophytes are terrestrial plants which are adapted to neither particularly dry nor particularly wet environments. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and Rosa multiflora. Mesophytes prefer soil and air of moderate humidity and avoid soil with standing water ...
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 ...
Endophyte. Transmission electron microscope image of a cross section through a soybean (Glycine max) root nodule. The nitrogen fixing bacteria, Bradyrhizobium japonicum, infects the roots and establishes a symbiosis. This high magnification image shows part of a cell with single bacteroid (bacterium-like cell or modified bacterial cell) within ...
They can tolerate burial in as much as 3 feet (0.9 m) of sand; sand burial stimulates the rhizomes to grow vertically, and is essential to plant vigor. [9] The beachgrass species are also very good examples of xerophytes, being able to thrive on arid to semi-arid beach dunes. The plant has several mechanisms for adapting to heat stress or wind.
