The highly specialized leaves of the Venus flytrap
(Dionaea muscipula) rapidly fold together in response
to a light touch by an unsuspecting insect, entrapping
the insect for later digestion. Attracted by
nectar on the leaf surface, the insect touches three
mechanically sensitive hairs, triggering the traplike
closing of the leaf (Fig. 1). This leaf movement is produced
by sudden (within 0.5 s) changes of turgor pressure
in mesophyll cells (the inner cells of the leaf),
probably achieved by the release of K ions from the
cells and the resulting efflux, by osmosis, of water. Digestive
glands in the leaf’s surface release enzymes
that extract nutrients from the insect.
The sensitive plant (Mimosa pudica) also undergoes
a remarkable change in leaf shape triggered
by mechanical touch (Fig. 2). A light touch or vibration
produces a sudden drooping of the leaves, the result
of a dramatic reduction in turgor pressure in cells
at the base of each leaflet and leaf. As in the Venus
flytrap, the drop in turgor pressure results from K
release followed by the efflux of water。

高度分化的维纳斯花篮(一种捕蝇草)收到昆虫的轻微触碰的时候会迅速收拢其叶片,通过这个方式诱捕昆虫,之后再消化。当收到叶片表面甘露的吸引时,昆梁银虫会触碰到3跟敏感的触毛,这会引起叶片的诱捕闭合行为。
叶肉细胞(正茄叶片内部的橡清宴细胞)突然性地改变膨胀压力而产生的叶片的动作,或许是由细胞中产生钾离子并且通过渗透作用导致水分流出产生的。
叶表面的消化细胞通过释放相关的酶来从昆虫身上提取营养物质。
感觉灵敏的植物(如含羞草)对于碰触其叶片形状也会发生明显的变化。一个轻微的触碰或震动便会产生叶片的突然弯曲,这是由小叶和叶片基部细胞中细胞组织膨胀压力大幅度减小造成的。
以维纳斯花篮为例,水分流出所伴随的钾离子的释放导致了细胞组织膨胀压力的减小。
