There may be as many as primary, secondary and tertiary.
plant cells have cell walls
Animal cells do not have cell walls. Many animal-like protists also lack cell walls.
No, only plant cells have cell walls! Animal cells have a cell membrane.

many cells. cell walls are found in plants, where the need stability and support to stay upright.
Fungal cell walls are primarily made of chitin, while plant cell walls are primarily made of cellulose. Fungal cell walls do not contain lignin, which is found in plant cell walls and provides rigidity. Additionally, fungal cell walls do not have chloroplasts like plant cell walls do.
cell walls
Animals do not have cell walls, animals cells with cell walls do not exist.

If you are referring to plant cell walls, then they are made up of primarily cellulose and carbohydrates. Even though carbohydrates do make up cell walls in plants, cellulose (a polymer of glucose {consists of many glucose molecules}) is the primary structural component of a plant cell wall.
No animal has cell walls. Only plants and certain protists have cell walls.
