https://www.youtube.com/watch?v=-bcgyQDE3AM Oxalis plants 🪴 have evolved a specialized mechanism to eject their seeds ballistically. When the protrusion on the aril (a specialized outgrowth covering the seed) is disturbed, cracks form and cause the aril to open and snap, transforming its stored strain energy to eject the seed at an optimal launching angle. 13 sec. #plants #biology #ecology #science
