Cell walls are only present in plant cells, cell walls protect the cell and allows the plant to grow to great heights.
This is the structure of the entire nucleus.
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun, cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves and vacuoles allow plant cells to change size.
The cell wall is the outermost layer of the cell because it protects and holds the cell together. This organelles main focus is as stated before to protect the plant cell and allow the plant the grow to new heights.
The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
As you can see the the cell wall surrounds the entire cell to protect it.
The cell wall relates to the school's physical walls they protect the school and everything in it just how the cell wall does for the cell.
