Rapid Plant Movement
Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds. The traps of Utricularia are much faster, closing in about 0.5 milliseconds. The dogwood bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the white mulberry tree, with flower movement taking 25 microseconds, as pollen is catapulted from the stamens at velocities in excess of half the speed of sound—near the theoretical physical limits for movements in plants.Taylor, P.E., G. Card, J. House, M. H. Dickinson & R.C. Flagan 2006. High-speed pollen release in the white mulberry tree, ''Morus alba'' L.. ''Sexual Plant Reproduction'' 19(1): 19–24. These rapid plant movements differ from the more common, but much slower "growth-movements" of plants, called tropisms. Tropisms encompass movements that lead to physical, per ...

Venus Flytrap Showing Trigger Hairs
Venus is the second planet from the Sun. It is often called Earth's "twin" or "sister" planet for having almost the same size and mass, and the closest orbit to Earth's. While both are rocky planets, Venus has an atmosphere much thicker and denser than Earth and any other rocky body in the Solar System. Its atmosphere is composed of mostly carbon dioxide (), with a global sulfuric acid cloud cover and no liquid water. At the mean surface level the atmosphere reaches a temperature of and a pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. Venus is the third brightest object in Earth's sky, after the Moon and the Sun, and, like Mercury, appears always relatively close to the Sun, either as a "morning star" or an "evening star", resulting from orbiting closer ( inferior) to the Sun than Earth. The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years. In t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterwheel Plant
''Aldrovanda vesiculosa'', commonly known as the waterwheel plant, is the sole extant species in the flowering plant genus ''Aldrovanda'' of the family Droseraceae. The plant captures small aquatic invertebrates using traps similar to those of the Venus flytrap. The traps are arranged in whorls around a central, free-floating stem, giving rise to the common name. This is one of the few plant species capable of rapid movement. While the genus ''Aldrovanda'' is now monotypic, up to 19 extinct species are known in the fossil record. While the species displays a degree of morphological plasticity between populations, ''A. vesiculosa'' possesses a very low genetic diversity across its entire range. ''A. vesiculosa'' has declined over the last century to only 50 confirmed extant populations worldwide. These are spread across Europe, Africa, Asia, and Australia. However, potentially invasive populations exist in the eastern United States. It is kept by hobbyists. Morphology ''Aldrov ...

Averrhoa Carambola
''Averrhoa carambola'' is a species of tree in the family Oxalidaceae native to tropical Southeast Asia; it has a number of common names, including carambola, star fruit and five-corner. It is a small tree or shrub that grows tall, with rose to red-purple flowers. The flowers are small and bell-shaped, with five petals that have whitish edges. The flowers are often produced year round under tropical conditions. The tree is cultivated in tropical and semitropical regions for Carambola, its edible fruits. Taxonomy The species in the genus ''Averrhoa'' along with the species in genus ''Sarcotheca'' are the only woody, tree-like plants belonging to the Oxalis family Oxalidaceae. The Oxalis family has nearly 900 species; most are herbaceous perennials or annuals native from tropical and semitropical locations, although a number also grow in other parts of the world. ''Averrhoa'' has sometimes been placed in the family Averrhoaceae. ''Averrhoa carambola'' is one of two species in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeschynomene Deightonii
''Aeschynomene'' is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic ''Dalbergia'' clade of the Dalbergieae. They are known commonly as jointvetches. They range across tropical and subtropical regions of the Americas, sub-Saharan Africa, south, southeast, and east Asia, and Australia. These legumes are most common in warm regions and many species are aquatic. The genus as currently circumscribed is paraphyletic and it has been suggested that the subgenus ''Ochopodium'' be elevated to a new genus within the Dalbergieae, though other changes will also be required to render the genus monophyletic. ''Plants of the World Online'' currently accepts 114 species. Species ''Aeschynomene'' comprises the following species: * ''Aeschynomene abyssinica'' (A. Rich.)

Mimosa Pudica
''Mimosa pudica'' (also called sensitive plant, sleepy grass, sleepy plant, action plant, humble plant, touch-me-not, touch-and-die, or shameplant) is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop when touched or shaken and re-open a few minutes later. For this reason, this species is commonly cited as an example of rapid plant movement. Like a number of other plant species, it undergoes changes in leaf orientation termed "sleep" or nyctinastic movement. The foliage closes during darkness and reopens in light. This was first studied by French scientist Jean-Jacques d'Ortous. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit. The species is native to the Caribbean and South and Central America, but is now a pantropical weed, and can now be found in the Southern United States, South Asia, East Asia, Micronesi ...

Thigmonasty
In biology, thigmonasty or seismonasty is the nastic movement, nastic (non-directional) response of a plant or fungus to touch or vibration. Conspicuous examples of thigmonasty include many species in the Fabaceae, leguminous family (biology), subfamily Mimosoideae, active carnivorous plants such as ''Dionaea (plant), Dionaea'' and a wide range of pollination mechanisms. Distinctive aspects Thigmonasty differs from thigmotropism in that nastic motion is independent of the direction of the stimulus. For example, tendrils from a climbing plant are thigmotropic because they twine around any support they touch, responding in whichever direction the stimulus came from. However, the shutting of a venus fly trap is thigmonastic; no matter what the direction of the stimulus, the trap simply shuts (and later possibly opens). The time scales of thigmonastic responses tend to be shorter than those of thigmotropic movements because many examples of thigmonasty depend on pre-accumulated turg ...
