The embedded proteins <u>allow specific substances to flow into the cell</u>.The phospholipid bilayer forms a stable barrier between two aqueous compartment.They embedded proteins carry the selective transportation of molecules and ensure their is cell to cell recognition.
Proteins are made by ribosomes and then folded into their correct shape inside the endoplasmic reticulum. These proteins are then taken to the Golgi apparatus, or body, to be modified and then placed into little sacs called vesicles to transport the proteins. The two organelles are related in how they are both involved in the assembly and transportation of proteins.

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
