Morphological Types of Green Algae Unicellular are both flagellated and non-flagellated Spirogyra reproduces by sexual reproduction known as conjugation ...a papillae forms between the cells of two different filaments and a diploid zygoyte is formed, then meiosis occurs to produce 4 haploid nuclei . They can also reproduce asexually by fragmentation . Distinguishing characteristics of each Phylum studied : Phylum Chlorophyta (green algae) – Believed to have given rise to terrestrial land plants, photosynthetic Phylum Dinophyta (dinoflagellates) – Cause red tides when over reproduce in warm water Phylum Bacillariophyta (diatoms) – Have ridged cell walls made of silica, bilateral and radial patterns Phylum Oomycota (water molds) – Are unicellular heterotrophic (non-photosynthetic) protists. Most are saprophytes or parasites Phylum Myxomycota (slime molds) – Are protists Phylum Zygomycota (black bread molds) – Characterized by nonseptate filamentous mycelium containing many nuclei Phylum Ascomycota (sac fungi/powdery mildews) – Somatic hyphae are septate (have cross-walls) Phylum Basidiomycota (club fungi) – Produce a basidium during their life cycle (eg. Mushrooms) Phylum Hepatophyta (liverworts) Phylum Bryophyta (mosses) Phylum Lycopodiophyta (club mosses/fern allies) Phylum Pteridophyta (ferns) Phylum Coniferophyta (conifers) Phylum Cycadophyta
