What are 2 prokaryotic organisms?
Bacteria and archaea are the two types of prokaryotes.
prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.
Bacteria are classified as prokaryotes, along with another group of single-celled organisms, the archaea.
Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast. They are single-celled and range in size from 0.2 to 10 microns (about 10 times smaller than most plant and animal cells).
- Escherichia Coli Bacterium (E. coli)
- Streptococcus Bacterium.
- Streptomyces Soil Bacteria.
- Archaea.
Prokaryotes are a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and archaea.
Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes—eu means true—and are made up of eukaryotic cells.
Out of the following options, the examples of prokaryotes are options (A) Algae and (C) Bacteria. Algae and bacteria are prokaryotes and prokaryotes are microorganisms that have no nucleus or other organs in them. These prokaryotes are divided into two different categories, which include archaea and bacteria.
Final answer: Algae and bacteria are examples of prokaryotes.
The number of validly named species of prokaryotes is currently slightly more than 6200.
What's in a prokaryotic cell?
All prokaryotic cells have a nucleoid region, DNA and RNA as their genetic material, ribosomes that make proteins, and cytosol that contains a cytoskeleton that organizes cellular materials. However, prokaryotic organisms are a very diverse group of organisms and come in many different shapes and sizes.
Also, fungi are non-photosynthetic organisms and are the group of eukaryotic organisms (organisms whose cells have a nucleus enclosed within membranes) that includes microorganisms such as molds, yeasts, as well as mushrooms.

Organisms such as animals, plants, fungi, and protists are examples of eukaryotes because their cells are organized into compartmentalized structures called organelles, such as the nucleus.
- Plant cell.
- Animal cell.
- Fungi.
- Amoebae.
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
- Plant cell.
- Animal cell.
- Fungi.
- Amoebae.
Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes—eu means true—and are made up of eukaryotic cells.
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water.
Eukaryotes are highly organized unicellular or multicellular organisms, such as animals and plants. Prokaryotes, on the other hand, are basic single-celled organisms, such as bacteria and archaea. Amoebas are eukaryotes.
