Mimosa pudica was one of the four species that significantly extracted and bioaccumulated the pollutant into its leaves. [25] Other studies have found that Mimosa pudica extracts heavy metals such as copper, lead, tin, and zinc from polluted soils. This allows for the soil to gradually return to less toxic compositions.
Cyanobacteria can entrain to light pulses at a single cell level, but not all strains of the cyanobacteria entrain to light. While some cyanobacteria show rhythmic photosynthesis in constant light conditions, others exhibit constitutive photosynthetic activity in constant light conditions, measured by the levels of photosynthetic oxygen evolution.
The leaves of the sensitive plant, Mimosa pudica, close up rapidly in response to direct touch, vibration, or even electrical and thermal stimuli. The proximate cause of this mechanical response is an abrupt change in the turgor pressure in the pulvini at the base of leaves resulting from osmotic phenomena. This is then spread via both ...
Nitrogen is a fundamental chemical component of amino acids, the molecular building blocks of protein. As such, nitrogen balance may be used as an index of protein metabolism. [1] When more nitrogen is gained than lost by an individual, they are considered to have a positive nitrogen balance and be in a state of overall protein anabolism.
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 ...
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.
Benznidazole and nifurtimox often cause side effects, including skin disorders, digestive system irritation, and neurological symptoms, which can result in treatment being discontinued. [ 2 ] [ 8 ] New drugs for Chagas disease are under development, [ 9 ] and while experimental vaccines have been studied in animal models, [ 10 ] [ 11 ] a human ...
Acacia s.l. (pronounced / ə ˈ k eɪ ʃ ə / or / ə ˈ k eɪ s i ə /), known commonly as mimosa, acacia, thorntree or wattle, [2] is a polyphyletic genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae. It was described by the Swedish botanist Carl Linnaeus in 1773 based on the African species Acacia nilotica.
