Class Ulvophyceae

• Species have sporic meiosis so that an alternation of generations ( haploid & diploid) exists.
• These most marine species tend to have the most complex morphology, with 3D parenchymatous-like tissue
• Motile cells have their flagella arranged like the chlorophyceae described above.
