Cell Wall
The Cell Wall is a feature unique to plant cells. The wall has the ability to protect plant cells, maintain cell shape, and prevent excessive uptakes of water.
The chemical composition of cells walls vary by species and maybe even cells. However, they are still generally thicker than plasma membranes, and have a consistent design.
Young plants first create the primary cell wall, a thin and flexible wall. Middle lamellas appear between the primary cell walls of adjacent cells. These are layers made of up pectins.
As plants mature, they may reinforce their cell wall. Some may secrete hardening substances to their walls, while others might form a secondary cell wall. This can be found between the plasma membrane and plasma wall. These generally have multiple laminated layers that give the cell additional protection and support. Wood is an example of this.
