Plasma membrane defines the boundary of the cell and regulates the flow of material into and out of the cell. Ruptured plasma membrane generally heals within no time but if rupturing does not heal, the cell contents will spill over and cell is killed.

Without proteins, the plasma membrane would not be able to perform essential functions such as transport, cell signaling, and cell adhesion. Proteins are crucial for allowing specific molecules to pass through the membrane and for communication between the cell and its environment. Without proteins, the cell would likely not survive or function properly.
It would probably die. The necessary requirements of a cell would not be imported into the cell, and it would not be able to release wastes.
Cellulose, which is a carbohydrate found in the cell walls of plants, would not be found in an animal plasma membrane. Animal plasma membranes primarily consist of phospholipids, cholesterol, and proteins.
Non-examples of a plasma membrane include the walls of a water bottle, the cover of a book, and a glass window pane. These structures do not regulate the movement of molecules like a plasma membrane does in living cells.

If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face, what would happen to you?
Yes.

The membrane is the most exposed part of the cell, it is chemically active and comes into contact with many chemicals. DNA here would be exposed to possible damage. Having the DNA enclosed in the nucleus and nuclear membrane better protects this very important "director" from potential damage.
Not for a nanosecond.

Mitochondria would not be found in the plasma membrane of a human cell. Mitochondria are organelles responsible for cellular respiration and energy production, and they are typically found in the cytoplasm of the cell, not within the plasma membrane.

Large molecules would be able to enter and damage the nucleus.
