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.
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 cactus (pl.: cacti, cactuses, or less commonly, cactus) [3] is a member of the plant family Cactaceae (/ kækˈteɪsi.iː, - ˌaɪ /), [a] a family comprising about 127 genera with some 1,750 known species of the order Caryophyllales. [4] The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name ...
Xerophyte - A plant that is able to grow where the water supply is small. Xerophytes are plants that are able to control the loss of water from their aërial parts. Xerophytes employ many different tools to control the loss of water, such as; waxy deposits, varnish, or mineral crusts on the epidermis; reduction of air spaces; storage organs ...
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating.
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 ...
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25][26][27] 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats. [28]
Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
