Cell Wall structure and function



The function of the cell wall is to protect and support the cell as well as to help maintain the shape of the cell. Plant cells are generally more rectangular in shape because of the support from the cell wall. Cell walls are only found in plant cells.



The cell wall is made of a material call Cellulose (or Chitin) which is a rigid material. The cellulose helps make the cell wall strong to support the cell and protect the internal contents and organelles of the cell. Even though the cell wall is rigid materials such as water and oxygen which are necessary for photosynthesis can easily pass through.
