"Prokaryote" is shown in the given image.
Answer: Option A
<u>Explanation:</u>
A prokaryote is a single-cell organism which is deficient in a membranous nucleus, mitochondria, or any other membranous organs. Prokaryotes are categorized into two domains: Bacteria and Archaea. At the third domain: Eukaryota, species with nuclei and organelles are located.
The asexual prokaryotes reproduce without fusion of gametes. They are considered as first living organisms. In the prokaryotes components like proteins, DNA and metabolites, overall the intra-cellular water-soluble components are enclosed by the cell membrane as situated together in the cytoplasm, rather than in separate cellular compartments.
