Which statement regarding the movement in the sensitive plant (Mimosa pudica) is INCORRECT?
It is a seismonastic movement triggered by touch or other stimuli.
It involves the active transport of potassium ions into the pulvinus.
It is a nastic movement caused by changes in turgor pressure.
Water moves out of the pulvinus cells, leading to a decrease in turgor and leaf drooping.
