Domain Eukarya (most euks are single celled)

Kingdom Protista (controversial)

6. slime molds

Dictyostelium (single-celled, engulf bacteria in soil, can form spores, have an amoeboid stage)

Physarum (single cells that can fuse to form multinucleate slime mold)

Algae Photosynthetic protists

Green algae contain chlorophyll a and b

Chlamydamonas Volvox Spirogyra Oedogonium

Multicellular green

1. Unicellular 2. Colonial 3. Multicellular

Brown algae = multicellular seaweed
