A cellular component in the eubacteria that resembles eukaryotic cell is the plasma membrane and it is a phospholipid bilayer that contains protein. 

- Plasma membrane is semi permeable which allows the passage of selective substances through it. 

- In eubacteria the cell wall is made up of peptidoglycan whereas in some of the eukaryotes like fungi, cell wall is made up of chitin, and in plants it is made up of cellulose. 

- The nucleus is not bounded by any membrane in the eybacteria and it is called nucleoid. On the other hand, in eukaryotes, the nucleus is bounded by double membrane.

- Eukaryotic ribosomes are 80S types whereas in eubacteria ribosomes are 70S type. 

- A glycocalyx may exist outside the plasma membrane of eukaryotes, composed of carbohydrate chains from glycoproteins in cell membrane but glycocalyx is found in most bacteria, it is called capsule if it is attached tightly to the cell wall and called as slime layer if it is loosely attached to the cell wall.
