LISTĘ DES FIGURES

Figurę 2.1 Energy fluxes in PSII of six algal and three cyanobacteria species cxposcd to incrcasing glyphosate concentrations for a 48 hours period, based on the model developed by Force et al., (2003). A) Maximal PSII quantum yicld (Fv/F_m). B) Effective antenna sizc of an activc reaction center (ABS/RC).

C) Effcctive dissipation of an activc reaction center (DIq/RC). D) Maximal trapping ratę of PSII (TR<>/RC). E) Electron transport in an active reaction center (ETo/RC). The horizontal linę repesents the control treatment (100%).........27
