What is the cause of nastc movement found in mimosa pudica plant

Asked by saradamahapatra9999 | 23 Oct, 2020, 04:22: PM
Expert Answer
  • The movement of Mimosa pudica is driven by turgor pressure, which is the pressure exerted on the cell wall because of the movement of water into the cell.
  • The environmental stimuli induces an electrical signal (action potential) transmitted from touch-sensitive cells.
  • The action potential moves from cell-to-cell until it reaches specialized “motor cells” at the base of each leaf-blade or leaflet.
  • From here, movement occurs as the action potential translates into a chemical signal, which causes rapid efflux of potassium (K+) followed by water transport out of the motor cells due to osmosis.
  • The greater the intensity, the farther the signal will travel, resulting in greater movement.
  • As a result, there is a loss in cell pressure and cell collapse causing the leaves to close.
  • The leaves will usually return to their original orientation after 10-15 minutes.
