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.
In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. [1] Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems, where frequent wind and the open environment permit rolling without prohibitive obstruction. [2]
In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots ...
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] Nor are all succulents xerophytes, as plants such as Crassula helmsii are both succulent and aquatic. [9] The center rosette of Aloe polyphylla
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Agave (/ ə ˈ ɡ ɑː v i /; also UK: / ə ˈ ɡ eɪ v i /; [3] Anglo-Hispanic, also US: / ə ˈ ɡ ɑː v eɪ /) [4] is a genus of monocots native to the arid regions of the Americas.The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves.
It is a succulent xerophyte with a deep, well-developed root system and waxy leaf cuticle. The leaves are stiff, spiny, and leathery in texture. The leaves are stiff, spiny, and leathery in texture. The basal leaves, which measure 5 – 15 cm in length and are rolled when young, [ 9 ] are palmately 3-lobed and suborbicular, truncate, or cordate ...
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.
