Question

What specialized structures are present in prokaryotic cells

Answer 1

Prokaryotes may be defined as the organism that lacks the membrane bound cell organelle. The nucleus is absent in case of prokaryotic cells and their DNA is circular in shape.

The prokaryotes have well defined cell wall that protect them from the external environment, heat and shock. The sex pili helps in the sexual reproduction of prokaryotes. The surface to volume ratio is high as they have small cell size. The flagella or cilia helps them to move from one region to another. Transcription and translation are coupled in case of prokaryotes.

Answer 2

The correct answer will be- plasma membrane, plasma membrane extenison called pili, the cell wall, the DNA in the form of circular chromosomes and plamsid and the ribosomes

Step-by-step explanation:

Prokaryotes are the group of organisms which evolved during the primordial times which lacked life parameters like oxygen. The bacteria is the only group of the organism which belongs to the prokaryotic organisms. Since they evolved during the primitive period, therefore, they lacked membrane-bound organelles like nucleus, mitochondria, Golgi apparatus and other organelles.

Therefore the specialized structure includes the plasma membrane, plasma membrane extension called pili, the cell wall, the DNA in the form of circular chromosomes and plasmid and the ribosomes which synthesizes the proteins.
