According to this … Abstract: Oxygenic photosynthesis, the chemical process whereby light energy powers the conversion of carbon dioxide into organic compounds and oxygen is released as a waste product, evolved in the anoxygenic ancestors of Cyanobacteria. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts. Our first results indicate that the diversity of algal endoliths may be linked to environmental conditions, but this hypothesis needs further testing. Our research focuses on the origin, evolution and regulation of sexual systems diversity and on the molecular and evolutionary mechanisms that underlie the complex developmental patterns and reproductive features in the brown algae. Based on case studies in the green algae Codium and Halimeda, it is shown that lineages behave differently when it comes to their evolution of SST affinities, and that there is a strong correlation between the evolution of SST affinities and rates of species diversification. Similar to land plants, algae are at the base of the food chain, and, given that plants are virtually absent from the oceans, the existence of nearly all marine life—including whales, seals, fishes, turtles, … Information on the sites of cellulose synthesis and the diversity and evolution of cellulose‐synthesizing enzyme complexes (terminal complexes) in algae is reviewed.
