Answer:
The options are missing in the question, the options are;
a. an archaean
b. a Paramecium
c. a yeast (fungus) cell
d. a grasshopper cell
The correct answer is A (an archaean)
Explanation:
Archaea and Bacteria are domains where prokaryotes are commonly found. Archaea and Bacteria as prokaryotes are unicellular organisms that lacks membrane-bound organnelles and a well defined nucleus, in the sense that unlike eukaryotic cells, a nucleus does not house their genetic material (DNA), instead their single circular chromosome is nakedly localized in a region called the NUCLEOID.
In addition, prokaryotic cells lacks many organnelles found in eukaryotic cells e.g mitochondria, Endoplasmic reticulum, lysosome etc. The few ones like ribosomes found in their cytoplasm are not enclosed by lipid bilayers called membranes.
