cell membrane
The cell membrane keeps all parts of a cell intact. Plants have a rigid cell wall which is outside of the cell membrane.
Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.

The plasma membrane is a barrier that keeps the internal environment of a cell separate from the external environment. The plasma membrane helps control or monitor what substances (or what amounts of substances) do or do not enter or exit the cell. The plasma membrane helps to maintain homeostatis by keeping the conditions within the cell constant or ideal. Because of homeostatis, the contents of the cell don't get too dry, too wet, too salty, etc
The cell wall or membrane keeps it separate from the environment.
The cell keeps more molecules inside the membrane.The cell does not allow molecules to cross the membrane.The cell keeps most molecules outside the membrane.The cell keeps molecules balanced inside and out

The purpose of a cell membrane is that it controls what passes into and out of the cell.
Homeostasis keeps an organism's internal environment stable, even if the external environment is not. Examples include temperature of the body and the amount of water in the body

Yes. Homeostasis means that the organism's internal environment changes so it is not influenced by the outside environment.
keeps it from dispersing into the environment
