A cell surrounded by a protective covering is called a "cell membrane" or "plasma membrane." This semi-permeable membrane controls the movement of substances in and out of the cell, helping to maintain homeostasis. In addition to the cell membrane, some cells, like plant cells and bacteria, also have a rigid outer layer known as the cell wall that provides extra protection and support.
Cell wall
Every plant and animal cell is surrounded by a cell membrane. Plant cells have both a cell membrane and a cell wall because they can create there own food through photosynthesis. Animal cells have to absorb food, so they cant have a cell wall.
Yes
For most cells, it is the cell membrane. Cells have a plasma membrane that is very selectively permeable i.e, will allow entry of substances that are necessary for the cell functioning. In case of an egg cell, it is surrounded by follicular cells. It provides protection from various acidic conditions. For a plant cell, the cell wall serves as a barrier.
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.
As you can see below in a diagram of an animal cell, the cell membrane is the outer layer of the cell and lines the cytoplasm. In a plant cell, the membrane lines the cytoplasm however this time is surrounded by the cell wall.
The protective layer that covers the surface of a plant to prevent water loss is called the cuticle.

In animal cell it is surrounded by cell membrane. In plant cell it is surrounded by cell wall.
For plant cells, they have a cell membrane and covering the cell membrane is a cell wall. The cell wall is for the structure of the plant. For animal cells, they just have a cell membrane.
