Shooting Mechanisms in Nature: A Systematic Review
Fig 19
A regular plant cell consisting of a cell wall and cytoplasm. (B) Evaporation of water from the cell causes the radial walls to come closer together and the lateral wall to cave inwards. (C) The lateral wall is caved inwards completely. (D) When a critical pressure is reached, the cytoplasm fractures and a gas (cavitation) bubble appears, causing the walls to rapidly snap back to their original form.
