What makes up a plant cell wall?

Answer 1

Oh, dude, a plant cell wall is like the outer layer of a plant cell made up of cellulose, hemicellulose, and pectin. It's basically the plant's way of saying, "Hey, I need some structure and support, so I'm gonna build this tough wall around me." So, yeah, it's like the plant's version of a sturdy fortress to keep everything in place.

Answer 2

Composition of Cell Wall:

The major Carbohydrates making up the primary (budding) plant cell wall are cellulose, hemicellulose and pectin. The cellulose microfibrils are linked through hemicellulosic chains to form the cellulose-hemicellulose web, which is fixed in the pectin matrix. The most common hemicellulose in the primary cell wall is xyloglucan. In grass cell walls, xyloglucan and pectin are sometimes partially replaced by glucuronarabinoxylan.The outer part of the primary cell wall of the plant epidermis is usually impregnated with cutin and wax, forming a permeability barrier known as the plant cuticle.

Secondary cell walls contain a wide range of other compounds that modify their mechanical properties and permeability. The major polymers that make up wood (largely secondary cell walls) include cellulose (35 to 50%), xylan (20 to 35%) and lignin (10 to 25%). The walls of cork cells in the bark of trees are impregnated with suberin, and suberin also forms the permeability barrier in primary roots known as the Casparian strip. Secondary walls - especially in grasses - may also contain microscopic silica crystals, which may strengthen the wall. These silica crystals also ensure the survival of plant by saving them from getting grazed by herbivores.

All these compounds working in coordination make the cell wall unbreakable.

Cell Walls in Fungi:

Fungal cell walls are made of chitin, the same material from which exoskeletons of insects are made, it is a polymer of glucosamine.

Cell Walls in Diatoms:

Diatomic cell walls are composed of Silicic Acid which is a compound of silicon, oxygen and hydrogen.

Bacterial Cell Walls:

In Eubacteria, cell walls are of peptidoglycan. In archaeobacteria, A variety of compounds make up cell wall for example Glycoproteins, Psuedopeptidoglycan and Polysaccharides.

Answer 3

A plant cell wall is primarily composed of cellulose, a complex polysaccharide made up of long chains of glucose molecules. It also contains other polysaccharides, such as hemicellulose and pectin, as well as structural proteins. The cell wall provides structural support and protection to the plant cell.

Answer 4

A plant cell wall is basically made of cellulose.

Answer 5

the cell wall of a plant cell is made up of many different things like sugars and cellulose. It can be made up of many different things though.

Answer 6

A cell wall surrounds the plasma membrane of plant cells and is made of cellulose. The plant cell wall is an outer covering of fibrous material, which gives the plant support and rigidity.
