A cell wall is a tough, flexible and sometimes fairly rigid layer surrounding a cell, located external to the cell membrane, which provides the cell with structural support, protection, and acts as a filtering mechanism. A major function of the cell wall is to act as a pressure vessel, preventing over-expansion when water enters the cell. They are found in plants, bacteria, fungi, algae, and some archaea.
Furthermore it keeps the right environment inside the cell in order for the chemical reactions in the cell to function properly. For example the reaction need to keep the right pH (Proton concentration) as well as other koncentrations (salt, nitrogen et.c.).
Furthermore it helps the cell to control the amounts of different proteins/enzymes inside the cell at any given time, which is very important, because there is a great interplay of different enzymes and it's reactants and products where the amount of one protein regulates the activity of many other proteins and enzymes, so forming a complex "regulatory network", that helps regulate the different functions in the cell, like breaking down food stuffs, reacting to outside signals, replicating DNA e.t.c. e.t.c. All this requires precise control over the amounts of the proteins/enzymes inside the cell.
It is also important to notice that many many of these proteins/enzymes are actually themselves placed in the membrane, having functions like keeping a concentration gradient over the membrane (different konc. outside and inside) of a certain substance, transporting molecules in/out, reacting to outside signals, et.c. et.c.

What are two functions of the cell wall?
The cell wall provides structural support and protection for the cell. It also helps regulate the movement of substances in and out of the cell.
What organelles is composed of the sugar cellulose and functions to give plant cells support?
The organelle composed of the sugar cellulose that provides support to plant cells is the cell wall. The cell wall is a rigid structure surrounding the cell membrane, maintaining the cell's shape and protecting it from mechanical damage.
Why dont animal cells have a cell wall?
Before answering this question, it is important to know the function of a cell wall. Cell walls are found in plants to provide rigidity to support the shape of the cell. Animals do not require those functions in cells, hence they do not need cell walls.
What are the key features and functions depicted in an onion cell diagram?
An onion cell diagram typically shows the key features and functions of a plant cell, such as the cell wall, cell membrane, nucleus, cytoplasm, and vacuole. These structures play important roles in maintaining the cell's shape, protecting its contents, and carrying out essential functions like storing nutrients and controlling cell activities.
Something that performs the same function as the cell wall?
The plasma membrane, also known as the cell membrane, functions similarly to the cell wall by providing structure, protecting the cell, and regulating what enters and exits the cell. It is a phospholipid bilayer that surrounds the cell and maintains its integrity.

The Functions of the cell wall and the cell membrane are different
How does a cellulose help with the functions of the cell wall?
Cellulouse makes the cell wall more rigid and hard to defend the cell.
