Rapid plant movement slower "growth-movements" of plants, called tropisms. Tropisms encompass movements that lead to physical, permanent alterations of the plant while rapid plant movements are usually reversible or occur at over a shorter span of time. A variety of mechanisms are utilized by plants in order to achieve these fast movements. Extremely fast movements such as the explosive spore dispersal techniques of "Sphagnum" mosses may involve increasing internal pressure via dehydration, causing a sudden propulsion of spores up or through the rapid opening of the "flower" opening triggered by insect pollination. Fast movement can also be expressed in predatory plants, where the
Peugeot Type 2 rudimentary suspension system pointed the way ahead regarding what would become another mainstream feature of the motor car. The main Peugeot business was, at this time, expanding rapidly its bicycle production, and the Type 2’s light weight may have incorporated lessons learned from cycle production. Four Type 2s were produced. Three were quadricycles while the fourth was a tricycle. They all had space for two on the bench above the engine.
