Nastic movements are important mechanisms in plants that act as defense against herbivory, blah blah. A nastic movement in the Mimosa pudica plant, or sensitive plant, is thigmonasty. This mechanosensory response is stimulated by touch or movement of the plant and causes the plant leaves to collapse on themselves. In order to understand how nastic movements are affected by its surroundings, this experiements will test thigmonasty in Mimosa pudica plants under 5 difference conditions. Four of the environments will have varying amounts of water and sunlight given to the plants during its growth period to understand how irregular conditions affect the nastic movements. A fifth environment will test the nastic movements of the plants under normal growing conditions. The nastic movements will be observed by timing the response closure time and reopening time of the leaves after touching the leaves with a cotton swab. Following data collection of each time interval ten times, overlapping graphs will be made to easily identified how the nastic movements times have been affected by each irregular environment compared to the control group.
