Do prokaryotes or eukaryotes have cell Wall?
Since this is not my area of expertise, I searched Google under the key words "prokaryotes vs eukaryotes" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

only plant cells have cell walls
Both prokaryotes and eukaryotes can have a cell wall, but the composition and structure of the cell wall differ between the two types of organisms.
1. Prokaryotes: Prokaryotes, which include bacteria and archaea, typically have a cell wall. The cell walls of bacteria are made primarily of peptidoglycan, a complex polymer of sugars and amino acids. The peptidoglycan provides structural support and protection for the bacterial cell. However, not all prokaryotes have cell walls. Some species of bacteria, called mycoplasmas, lack a cell wall and have a different mechanism for maintaining cell shape.
2. Eukaryotes: Most eukaryotic organisms, which include plants, fungi, and protists, have cell walls. However, the composition of eukaryotic cell walls is different from that of prokaryotes. For example:
- Plant cell walls: Plant cell walls are primarily composed of cellulose, a complex polysaccharide. The cellulose fibers provide strength and rigidity to plant cells. Other components of plant cell walls include lignin, pectin, and hemicellulose.
- Fungal cell walls: Fungal cell walls are composed of chitin, a tough carbohydrate polymer. Chitin gives fungal cells strength and protection.
- Protist cell walls: The composition of protist cell walls can vary widely depending on the specific species. Some protists have cell walls made of cellulose, similar to plant cells, while others may have silica-based cell walls or no cell walls at all.
In summary, both prokaryotes and eukaryotes can have cell walls, but the composition and structure of the cell walls differ between the two groups.
Prokaryotes have a cell wall, while eukaryotes may or may not have a cell wall depending on the specific type of cell. To understand this, it's helpful to know the differences between prokaryotes and eukaryotes.
1. Prokaryotes: These are single-celled organisms that lack a nucleus and membrane-bound organelles. They include bacteria and archaea. Prokaryotes have a cell wall, which serves as a protective layer surrounding the cell membrane. The cell wall provides structural support and helps to maintain the cell's shape.
2. Eukaryotes: These are more complex organisms, including animals, plants, fungi, and protists. Eukaryotic cells have a true nucleus enclosed by a nuclear membrane and various membrane-bound organelles. Some eukaryotic cells have a cell wall, while others do not.
- Plant cells: Plant cells are eukaryotic cells that have a cell wall composed mainly of cellulose. The cell wall provides rigidity and structural support to the plant cell.
- Fungal cells: Fungal cells are also eukaryotic and have a cell wall, typically made of a carbohydrate called chitin. The fungal cell wall helps maintain the shape and integrity of the cell.
- Animal cells: Animal cells are eukaryotic cells that generally do not have a cell wall. Instead, they have a flexible cell membrane that allows for cell movement and shape changes.
In summary, prokaryotes have a cell wall, while eukaryotes may or may not have a cell wall depending on the specific type of cell.
