Protists and Supergroups
Diatoms – SAR - Stramenopila
Foraminiferans – SAR - Rhizaria
Plasmodial slime molds - Unikonta - Amoebazoans
Trichomonas vaginalis - Excavata - Parabasalids
Giardia intestinalis - Excavata - Diplomonads
Dinoflagellates - SAR - Alveolata
Green algae - Archaeplastida- Chlorophytes
Brown algae - SAR-Stramenopila
Explanation:
Protists are the simplest eukaryotes. Due to their vast diversity of species, they are broadly divided into four supergroups or the clades. They are the Archaeplastida, Excavata, SAR clade, and Unikonta.
Archaeplastida: Interrelated with DNA sequence, cell structure, and endosymbiotic relationships. Divided into red algae, chlorophytes, charophyceans, and the plants. Eg, red algae, green algae, plants.
Excavata: Protists with cytoskeletal features like excavated grooves. This clade includes diplomonads, parabasalids, euglenozoans. Eg., Trichomonas and Giardia species
SAR: Protists interrelated with their DNA sequences and endosymbiotic relationships. Further divided into alveolata, stramenopila, and rhizaria. Eg., diatoms, dinoflagellates
Unikonta: Protists with flagella like structures, pseudopodia, genes fused together. Divided into amoebozoans and opisthokonts. These include slime molds, fungi, entamoebas, animals etc.
