Mimosa pudica (also called sensitive plant, sleepy plant, [citation needed] action plant, humble plant, touch-me-not, touch-and-die, or shameplant) [3] [2] 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 ...
Temperature has a multiplicity of effects on plants depending on a variety of factors, including the size and condition of the plant and the temperature and duration of exposure. The smaller and more succulent the plant, the greater the susceptibility to damage or death from temperatures that are too high or too low. Temperature affects the ...
Wilting also serves to reduce water loss, as it makes the leaves expose less surface area. [1] The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may ...
Applies e.g. to stele s and flowers in which the perianth segments within each whorl are alike in size and shape. Compare regular. Contrast asymmetrical, irregular, and zygomorphic. aculeate Armed with prickle s, [13] e.g. the stem of a rose. acumen A long, tapering point, especially the apex of an acuminate leaf. acuminate
Outside Araceae, the sacred lotus (Nelumbo nucifera) is thermogenic and endothermic, able to regulate its flower temperature to a certain range, [7] an ability shared by at least one species in the non-photosynthetic parasitic genus Rhizanthes, Rhizanthes lowii.
Its pH tolerance is estimated at 5.0–7.5. Leaves are killed by frost and plants do not tolerate water temperatures more than 34 °C (93 °F). Water hyacinths do not grow where the average salinity is greater than 15% that of sea water (around 5 g salt per kg). In brackish water, its leaves show epinasty and chlorosis, and eventually die ...
At the same time, hot weather is a killer: The EPA says there were 11,000 deaths in the U.S. directly caused by heat exposure between 1979 and 2018, and likely more where it was not listed or ...
Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
