Vacuoles:

 

    large liquid-filled storage containers found in plant cells. Plant cells can put virtually anything in their vacuoles, from nutrients to wastes to water to pigments. Vacuoles can be quite large, allowing plant cells to grow to substantial -volumes without making new cytoplasm. Some animal cells in freshwater microorganisms have specialized contractile vacuoles that pump water out of the cell to prevent bursting.

 

    Cell wall:

 

    Plant cells have a rigid cell wall surrounding their cell membrane. This wall is made of a compound called cellulose. The tough wall gives the plant cell added stability and protection from harm.
