Answer

Alveolates: These organisms are characterized by membrane-bounded sacs called alveoli underneath their membrane. They are protists and have cortical alveoli. Excavates: These organisms make up a kingdom of unicellular eukaryotes that lack traditional mitochondria, instead possessing a modified mitochondrial organelle. Stramenopiles: This eukaryotic group consists mostly of algae and can be unicellular or multicellular. Rhizaria: This organism makes up a supergroup of unicellular prokaryotes, usually amoeboids that are capable of producing complex shells or skeleton. Nearly all Rhizoids have mitochondria and tubular cristae Amoebozoans: A major group of (mostly) unicellular amoeboid protozoa, common in soils and aquatic habitats and vary greatly in size.
