The prokaryotic cell consists of the following characters
1]Prokaryotes lack an organized nucleus and other membrane-bound organelles.
2]Prokaryotic DNA is found in a central part of the cell called the nucleoid.
3]The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.
3]Prokaryotic cell size ranges from 0.1 to 5.0 μm in diameter.
4]The small size of prokaryotes allows quick entry and diffusion of ions and molecules to other parts of the cell while also allowing fast removal of waste products out of the cell.
So, the correct option is 'B'.
