Laser microbulles to test the pressure of plant cells - Université Grenoble Alpes

Using the nucleation of microbulles by laser, physicists, including Grenoblus, have shown that stomata, the miniature "doors" that regulate light evaporation in vascular plants, remain inactive in non-vascular plants such as mosses. Water pressure inside plant cells is very high, reaching dozens of bars. This "turge pressure" is used to grow plants and contributes to their mechanical hold. Its modulation is also intimately linked to the opening …
