There are more than one kind of cell.
If it is an animal or bacteria cell, than the cell membrane separates it.
If it is a plant cell, than the cell wall separates it.

cell membrane or cell wall
Cell membrane
cell membrane for all cells and a cell wall for plants(plants still do have cell membranes)Cell Membrane.
The cell membrane controls what comes in and out of cells.
Cells do live in a solid environment. In humans, cells thrive inside the body and are unable to live outside. In plants, cells live in rain forest environments and near rivers, streams, ponds but not in desert environments.
These cells have ionic channels that allow for flow of ions between cells.
Sertoli cells, a kind of sustentacular cells.

Skin cells.
A cell membrane, or cell wall.
It's enclosed by a barrier known as plasma membrain.
The barrier between the external environment and the inside of the cell is the cellular membrane, or just cell membrane. A cell wall is also present in plant cells, but substances can still enter through the cell wall. Harmful substances are stopped only when reaching the cell membrane. Some unicellular bacteria (or viruses) form an external layer outside the cell membrane, known as an envelope.
to make a barrier from the environment? to repair other damaged/dead cells via mitosis.
