-These are on the OUTSIDE of the plant cell PLASMA MEMBRANES.
-They are made of CELLULOSE (A CABOHYDRATE POLYMER made up of GLUCOSE subunits).
-The CELLULOSE forms a SIEVE- like NETWORK of STRANDS that make the wall strong.
-It is held rigid by the PRESSURE of the fluid inside the cell (TURGOR pressure), it SUPPORTS the cell and so helps SUPPORT the whole plant.
