Which specific cellular mechanism in cnidarians allows for the rapid discharge of nematocysts, considering the internal osmotic pressure is significantly higher than the surrounding seawater?
Passive diffusion of water into the cnidocyte, increasing internal pressure
Active transport of sodium ions out of the cnidocyte, creating an osmotic gradient
Rapid influx of calcium ions triggering forceful contraction of surrounding myoneme cells
Enzymatic breakdown of the cnidocil cap, releasing stored elastic energy
