Evolution of Plants

“Algae” a common name that includes organisms from 2 different Domains (3 kingdoms)

Where “Algae” are Found: 4 D: Archaea –K: Archebacteria D: Bacteria……………….bluegreen algae –K: Bacteria 4 D: Eukarya –K: Fungi –K: Protista (Protocista)…green,brown, red... algae –K: Plantae (Phyta) –K: Animalia

D: Eukaryota K: Protista (Divisions)“algae”-

K: Protista Div: Chlorophyta 4 Filamentous: –Oedogonium –Ulothrix Haplontic life cycle Monobiontic (n) –haploid or diploid –one or other

K: Protista Div: Chlorophyta –Ulva –Isomorphic –life cycle –Dibiontic haploid & diploid
