LIFE SCIENCE

Detailed explanation-1: -Final answer: Algae and bacteria are examples of prokaryotes.

Detailed explanation-2: -Thus, examples of prokaryotes include bacteria, archaea, and cyanobacteria (blue-green algae).

Detailed explanation-3: -The two prokaryotic domains (Archaea and Bacteria) each comprise several smaller taxonomic groupings. Within the Archaea are the euryarchaeotes, crenarchaeotes, nanoarchaeotes, and korarchaeotes. Within the Bacteria are proteobacteria, chlamydias, spirochetes, cyanobacteria, and gram-positive bacteria.

Detailed explanation-4: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
