The walls of the arteries are very thick in fact artery walls consist of three cell layers.
capillary walls are very thin, often a cell thick. artery walls have two thick layers.

no cell acts as a cell wall. cell walls are made of a two layers of lipids.
Only 3 kingdoms have cell walls, Protista, Fungi, and Plantae. The cell wall makeup can vary between species of the same kingdom and even between developmental stages of the cell. The most common substance is cellulose in plants.
Plants have cell walls that provide structure and prevent collapsing of the stem/trunk. The cell walls contain a component called lignin which has a high tensile strength, the cwell walls act a bit like scaffolding to keep the plant upright. Hope this helps.
Yes - plant cell walls can have up to three layers. The middle lamella is the outermost layer and contains high levels of pectin. The primary cell wall is a thin, flexible layer found in the middle. The secondary cell wall is a thicker layer on the inside.
In Plants: Basically, cell walls contain CELLULOSE. Cellulose is a polysaccharide, a carbohydrate (am macro molecule). Cellulose forms linear chains that join together to form microfibrils. These microfibrils form alternating layers. These layers of lattices are held together by hydrogen bonds, giving the cell wall strength. In fungi: Cell walls have CHITIN. In Bacteria: Bacteria cell walls contain PEPTIDOGLYCAN, formed by cross-linked polysaccharide chains.
No, absolutely not- cell walls are a characteristic of plants, bacteria and fungi- animal cells do not have cell walls ever. They have cell membranes, which are less rigid and less resistant to damage.
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.
Animals do not have cell walls, animals cells with cell walls do not exist.
