Streptophyta • Zygnematales • unicellular and filamentous forms • haplontic isogamous life cycle • Spirogyra - focus on conjugation and rudimentary phragmoplast • desmids - focus on complex morphogenesis in a single cell • Coleochaetales • filamentous or parenchymatous • haplontic oogamous life cycle • Coleochaete - focus on gametophyte-zygote nutritional relationship (matrotrophy) • Charales - basic structure and life cycle • evolution of cell division patterns in Streptophyta
