• A. moss and sponge
• B. yeast and amoeba
• C. bacteria and a blue-green algae
• D. penicillium and spirogyra

Answer 1

The correct option is C

bacteria and a blue-green algae

The correct option is option C.

Explanation for the correct option:

Prokaryotes:

1. Prokaryotic cells comprise bacteria and archaea.
2. A prokaryote is a unicellular organism.
3. They lack nuclei and other membrane-bound organelles except for ribosomes.
4. Nucleoids (DNA), ribosomes, cell membranes, cell walls, and a sort of surface layer that might be an integrated part of the wall are the five parts and essential structures of a prokaryotic cell.

Bacteria:

1. Bacteria are ubiquitous, primarily free-living single-celled organisms.
2. Bacteria are classified as prokaryotes since they don't have nuclei or membrane-bound organelles.

Blue-green algae:

1. It is also known as Cyanobacteria.
2. They are photoautotrophic prokaryotes.
3. Blue-green algae are classified as prokaryotes since they don't have nuclei or membrane-bound organelles. The genetic material is present in the cytoplasm.

Final Answer: Bacteria and blue-green algae are prokaryotes.
