False, both eukaryotic and prokaryotic cells have cell walls.
The only minor difference between their cell walls is that eukaryotic cell walls are made of cellulose, whilst prokaryotic cell walls are made from murein.
There are other many characteristics which distinguishes the eukaryotes from the prokaryotes. The MAIN DIFFERENCE between the two are their forms of DNA.
Eukaryotic DNA is found in the nucleus of cells, with the form of DNA being double stranded and are a double helix shape.
Prokaryotic DNA on the other hand, are found in the form of plasmids (rings of DNA) and are located in the cytoplasm. There is also a highly concentrated region of long, circular DNA called a nucleoid which is also located in the cytoplasm.
