Dunia Protista Protozoa Algae Slime molds
Phylogeny of Protista • Many biologists propose different phylogeny. Highly diverse and dynamic. • Kingdom is polyphyletic (members of taxon from two or more ancestral forms) • Nucleic acid sequencing, cell structure attempting to create monophyletic groups. • Have enabled systematists to create additional kingdom-level groupings. • Splitting Kingdom Protista into 3 separate kingdoms (Archaezoa, Protista/Protozoa, Chromista) • or 5 “candidate kingdoms” (Archaezoa, Euglenozoa, Alveolata, Stramenopila, Rhodophyta)
Three-domain tree of life based on small subunit rRNA sequences (modified from N.R. Pace, ASM News 62:464, 1996).
Klasifikasi Dunia Protista • Protozoa (Animal ike) • Algae (Plant-like) • Slime molds (Fungus-like)
A. Protozoa (1) Sistem klasifikasi tradisional: • Kelompok Ciliophora • Kelompok Mastigophora • Kelompok Sarcodina • Kelompok Sporozoa
Sistem klasifikasi menurut Komite sistematik dan evolusi Protozoa (1980): • Phylum Labirinthomorpha • Phylum Sarcomastigophora • Phylum Ciliophora • Phylum Apicomplexa • Phylum Microspora • Phylum Acetospora • Phylum Myxospora
Sistem klasifikasi (Cavalier-Smith; 1993): • Phylum Apicomplexa • Phylum Choanozoa • Phylum Ciliophora • Phylum Dinozoa • Phylum Entamoebia • Phylum Euglenozoa • Phylum Haplosporidia • Phylum Heliozoa • Phylum Mesozoa • Phylum Metamonada • Phylum Microsporidia • Phylum Mycetozoa • Phylum Myxosporidia • Phylum Opalozoa • Phylum Parabasalia • Phylum Paramyxia • Phylum Percolozoa • Phylum Radiozoa • Phylum Reticulosa • Phylum Rhizopoda
Bedasarkan sistem klasifikasi filogenetik: • Protozoa terdiri dari: Archeozoa dan Protozoa • Dunia Archeozoa: • Phylum Metamonada • Phylum Microsporidia • Phylum Parabasalia • Dunia Protozoa : • Phylum Eulenozoa • Phylum Entamoebia • Phylum Mycetozoa • Phylum Ciliophora • Phylum Dinozoa • Phylum Apicomplexa • Phylum Rhizopoda
B. Algae • Sistem klasifikasi tradisional: • Divisio Chlorophycophyta • Divisio Chrisophycophyta • Divisio Cryptophycophyta • Divisio Euglenophycophyta • Divisio Phaeophycophyta • Divisio Pyrrophycophyta • Divisio Rhodophycophyta
Sistem klasifikasi filogenetik (18S rRNA): • Algae sebagian masuk ke Protozoa, dan sebagian lagi masuk ke Tumbuhan lalu sisanya masuk dalam Dunia Chromista. • Dunia Chromista: • Phylum Haptophyta • Phylum Cryptista • Phylum Chloraciniophyta • Phylum Chrisopycea • Phylum Phaeopycea • Phylum Xanthopycea • Phylum Eustimatopyea • Phylum Diatomea • Phylum Oomycetidae • Phylum Thraustochitridae
