The plasma membrane is the living boundary of all cells and in some organisms it is externally covered by a cell wall.

In plant cells, the plasma membrane is surrounded by a cellulose cell wall that provides rigidity and protection.

In bacterial cells, the plasma membrane is covered by a peptidoglycan cell wall which maintains cell shape and prevents bursting.

In fungi and algae, the plasma membrane is also covered by a cell wall made of chitin (fungi) or cellulose (algae).

Therefore, the plasma membrane is covered by a cell wall in plants, bacteria, fungi, and algae, making All of the above the correct answer.
