A xerophyte (from Ancient Greek ξηρός (xērós) 'dry' and φυτόν (phutón) '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.
Plants adapted to living in dry environments such as succulents, are termed xerophytes. Not all xerophytes are succulents, since there are other ways of adapting to a shortage of water, e.g., by developing small leaves which may roll up or having leathery rather than succulent leaves. [8]
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. This means that during dry climatic conditions, they lose chlorophyll and cease photosynthesis and ...
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.
Raunkiær's life-form scheme has subsequently been revised and modified by various authors, [6] [7] [8] but the main structure has survived. Raunkiær's life-form system may be useful in researching the transformations of biotas and the genesis of some groups of phytophagous animals.
As a xerophytic adaptation, its leaves curl during drought (see pictures). The relatively high humidity within the curled leaf prevents a rapid water loss. This is facilitated by the bulliform cells located at the base of the V-shaped notch which swells and makes the leaf uncurl when filled with water. [8]
Houseplants. Indoor plants can still release pollen, sap, or spores, and can also collect mold and dust. Symptoms of a plant allergy may include runny nose; itchy eyes, throat, and/or ears; skin ...
Since CAM is an adaptation to arid conditions, plants using CAM often display other xerophytic characters, such as thick, reduced leaves with a low surface-area-to-volume ratio; thick cuticle; and stomata sunken into pits. Some shed their leaves during the dry season; others (the succulents [13]) store water in vacuoles. CAM also causes taste ...
