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 ...
Mimosa pudica is well known for its rapid plant movement. The leaves close up and droop when touched. However, this is not a form of tropism, but a nastic movement, a similar phenomenon. Nastic movements are non-directional responses to stimuli (e.g. temperature, humidity, light irradiance), and are usually associated with plants.
Mimosa microphylla, commonly called littleleaf sensitive-briar, eastern sensitive-briar, or little leaf mimosa, [1] [2] [3] is a species of flowering plant in the legume family . It is a perennial herb native [ 4 ] to North America, where it is found primarily in the southeastern United States.
In 2014, Monica Gagliano conducted experiments into long-term plant memory using Mimosa pudica, a plant unique for its ability to curl its leaves in defense against touching or shaking. In Gagliano’s experiment, the plants were repeatedly dropped from a prescribed height, shaking the branches and eliciting a defense response.
Mimosa pudica also show thermotropism by the collapsing of leaf petioles leading to the folding of leaflets, when temperature drops. [1] The term "thermotropism" was originated by French botanist Philippe Van Tieghem in his 1884 textbook Traité de botanique. Van Tieghem stated that a plant irradiated with an optimum growth temperature on one ...
Slower movement, such as the folding of Mimosa pudica leaves, may depend on reversible, but drastic or uneven changes in water pressure in the plant tissues [5] This process is controlled by the fluctuation of ions in and out of the cell, and the osmotic response of water to the ion flux.
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
