Cell membrane.
yes the cell membrane is the protective layer around cells that's underneath the cell wall.

Cork cells form a protective layer around plant stems.
The basal cell layer contains special cells called:
The outer surface layer of cells in plants is called the epidermis. In animals, the outermost layer of cells is called the epithelium. Both serve as protective barriers, regulate the exchange of substances, and provide a first line of defense against pathogens.
The outermost layer of the epidermis, known as the stratum corneum, is comprised of cells called corneocytes that are protective but nonviable. These cells are essentially dead and serve to provide a barrier against external aggressions like pathogens and UV radiation.

protects skinThe function of the cells in the epidermis is to die and form a protective layer around the body.
The outermost layer of a root is called the epidermis. It is a single layer of cells that protects and covers the root. In stems and leaves, the outermost layer is also called the epidermis, and it serves a similar protective function.
The protective outer layer of both animal and plant cells is called the cell membrane. It regulates the passage of substances in and out of the cell, maintaining the cell's internal environment and protecting it from external threats.
The epithelium that lines the body cavity is called mesothelium. It consists of a layer of flat cells called mesothelial cells that form a protective covering over organs in the body cavities.
The protective layer around the lungs is called the pleura. It is a thin, double-layered membrane that surrounds the lungs and helps to reduce friction between the lungs and the chest cavity as they expand and contract during breathing.
