What is the changes in the atti Patti plant?

Answer:
Mimosa pudica[2] (from Latin: pudica "shy, bashful or shrinking"; also called sensitive plant, sleepy plant, action plant,[3] touch-me-not, shameplant[1]) is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae and Magnoliopsida taxon, often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, defending themselves from harm, and re-open a few minutes later.[4] In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.[3][5]
The species is native to South and Central America, but is now a pantropical weed, and can be found in Southern United States, South Asia, East Asia and South Africa as well. It is not shade tolerant, and is primarily found on soils with low nutrient concentrations[6] Mimosa pudica is well known for its 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.[7] This was first studied by the French scientist Jean-Jacques d'Ortous de Mairan. Due to Mimosa's unique response to touch, it became an ideal plant for many experiments regarding plant habituation and memory
Mimosa pudica contains the toxic alkaloid mimosine, which has been found to also have antiproliferative and apoptotic effects.[31] The extracts of Mimosa pudica immobilize the filariform larvae of Strongyloides stercoralis in less than one hour.[32] Aqueous extracts of the roots of the plant have shown significant neutralizing effects in the lethality of the venom of the monocled cobra (Naja kaouthia). It appears to inhibit the myotoxicity and enzyme activity of cobra venom.[33]
Mimosa pudica demonstrates both antioxidant and antibacterial properties. This plant has also been demonstrated to be non-toxic in brine shrimp lethality tests, which suggests that M. pudica has low levels of toxicity. Chemical analysis has shown that Mimosa pudica contains various compounds, including "alkaloids, flavonoid C-glycosides, sterols, terenoids, tannins, saponin and fatty acids".[34][35] The roots of the plant have been shown to contain up to 10% tannin. A substance similar to adrenaline has been found within the plant's leaves. Mimosa pudica's seeds produce mucilage made up of D-glucuronic acid and D-xylose. Additionally, extracts of M. pudica have been shown to contain crocetin-dimethylester, tubulin, and green-yellow fatty oils. A new class of phytohormone turgorines, which are derivatives of gallic acid 4-O-(β-D-glucopyranosyl-6'-sulfate), have been discovered within the plant.[11]
The nitrogen-fixing properties of Mimosa pudica contribute to a high nitrogen content within the plant's leaves. The leaves of M. pudica also contain a wide range of carbon to mineral content, as well as a large variation in 13C values. The correlation between these two numbers suggests that significant ecological adaptation has occurred among the varieties of M. pudica in Brazil.[29]
The roots contain sac-like structures that release organic and organosulfur compounds including SO2, methylsulfinic acid, pyruvic acid, lactic acid, ethanesulfinic acid, propane sulfinic acid, 2-mercaptoaniline, S-propyl propane 1-thiosulfinate, and thioformaldehyde, an elusive and highly unstable compound never before reported to be emitted by a plant.[36]
