Glycocalyx "sugar coat",
|
-Cushions the plasma membrane and protects it from chemical injury
-Binds cells together so that tissues do not fall apart |
|
Tight Junction
|
-Series of proteins that interlock and prevent extracellular material from infultrating

|
Gap Junctions
|
-Similar to Plasmadesmata
-little pores that allow the penetration of small solutes from one cell to the next(communication channels between the cells. |
|
Fibronectin
|
-a high-molecular-weight extracellular matrix glycoprotein containing about 5% carbohydrate that binds to membrane spanning receptor proteins called integrins. In addition to integrins, they also bind extracellular matrix components such as collagen, fibrin and heparan sulfate.
