No, they are not!
Plant cells and prokaryotic cells share the presence of a cell wall, which is a rigid structure that provides support and protection. Animal cells do not have a cell wall, as they are surrounded by a flexible plasma membrane instead.
In general most prokaryotes do have cells walls. However, there are some prokaryotes such as the bacterial genus Mycoplasma that do not posses cell walls.

Yes, prokaryotic cells can be either gram positive or gram negative. This is determined by the structure of their cell walls and how they react to the Gram staining technique. Gram-positive bacteria have a thick layer of peptidoglycan in their cell walls, while gram-negative bacteria have a thinner peptidoglycan layer surrounded by an outer membrane.
Plant cells have strong web-like cell walls made of cellulose. The cell wall provides structural support and protection to the cell.
No. Some bacteria, like mycoplasmas, lack cell walls.

Prokaryotic cells have walls.

they are prokaryotic and therefore only have a cell membrane only plant cells have cell walls
cells walls in a animal cells
In general most prokaryotes do have cells walls. However, there are some prokaryotes such as the bacterial genus Mycoplasma that do not posses cell walls.
When DNA is not surrounded by a nuclear membrane, the cell is called a prokaryotic cell. Prokaryotic cells lack a nucleus, so the DNA is located in the cytoplasm in a region called the nucleoid. Examples of prokaryotic cells include bacteria and archaea.

Yes. They are.
Actually, cell walls are found in both prokaryotes and eukaryotes. In plants (eukaryotic) the cell walls are composed of cellulose whereas in prokaryotes, the cell walls are composed of peptidoglycan.
