Figure 2From: Effects of Cu2+, Ni2+, Pb2+, Zn2+ and pentachlorophenol on photosynthesis and motility in Chlamydomonas reinhardtii in short-term exposure experimentsThe dependence of photosynthetic response curves in C. reinhardtii to different concentrations of nickel (mg l-1) after 24 h exposure: a) 0.1, b) 0.5, c) 1.0, d) 1.5, e) 2.0. Thick solid line - oxygen evolution, thin dashed line - light evolution.Back to article page
