If you mean as this as impenetrable, no water or waste could come in or out. The cell would then be a non living object, or a 'dead cell'.
Do you mean hard as in solid? because if it was solid, you would not be alive.
it would cause the cell to lose all of its contents to the outside
If materials could not move across the cell membrane, the cell would not be able to take in essential nutrients or release waste products, leading to a lack of energy production and buildup of toxins. This would eventually lead to cell dysfunction and death.
It would depend on the extent of the damage to the cell membrane. If there is only minor damage to the membrane, the cell will produce the necessary proteins, fats and carbohydrates to repair the damage, and work towards returning to homeostasis. If the damage is extensive, the cell will lyse and die, as it is no longer able to maintain homeostasis.
No, if a cell membrane suddenly became permeable to all substances, it would not be able to maintain its internal environment or control the flow of molecules in and out of the cell. This would disrupt essential processes such as maintaining proper concentrations of ions and nutrients, leading to cell dysfunction and eventually death.
No, all cells have a cell membrane that acts as a protective barrier around the cell. It controls the movement of substances in and out of the cell, maintaining its internal environment. Without a cell membrane, the cell would not be able to survive.

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.
It would die as harmful substances enteres the cells.
The cell would die as it couldn't maintain homeostasis.

The world would explode
