Absence of rbc absence of cell wall

Explanation:

............

Answer 2

The typical feature of a prokaryotic cell is the absence of a membrane-bound nucleus.

• A prokaryotic cell lacks a well-developed nucleus as well as all other membrane-bound organelles like mitochondria, Golgi, endoplasmic reticulum, etc.
• A plasma membrane surrounded the prokaryotic cell boundary as well as DNA and RNA both are present in Prokaryotes.
• Membrane-bound cell organelles such as Mitochondria, Golgi apparatus, and Chloroplasts are absent.
• A membrane-bound well-defined nucleus is absent.
• Genetic material is circular DNA and occurs naked in the cell cytoplasm. It is attached to the cell membrane and is called the nucleoid.
• The cell size ranges from 0.1 to 5.0 micrometers in size.
• The cell wall is a rigid structure that is made up of polysaccharides.
