Yes, how else could the cell live. Cell membranes have structures (holes) in them to allow things to move in and out. These holes are special structures in the membrane and they "control" what goes across the membrane.
I have made a link below to a diagram of the cell membrane to show some of these structures.

What is The plasma membrane helps to maintain a cells what?
The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
What is a complex molecule that is embedded in the cell membrane that helpss move substances move into and out of a cell?
Transport protein
Which type of molecule can move passively across the membrane?
Water can move passively through a membrane by moving through the pores of a cell. Other substances cannot move through a cell membrane.
Does Phagocytosis move substances out of a cell?
Phagocytosis is the process of moving solids across a cell membrane into a cell.
What Controls what moves into cells?
The Cell Membrane is usually attributed with controling which substances can move in and out of the cell.
What controls which substances can move in and out of cells?
Cell membrane controls which substances can move in and out of a cell. It is the dynamic boundary of cell

What controls which substances can move in and out of a cell?
The cell membrane regulates the movement of substances in and out of the cell.How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.
Which part of a plant allows certain substances to move in and out of the cell?
the cell membrane
What does a plasma membrane protein do?
Helps substances move in and out of the cell

What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
What is the barrier around the that lets substances move across it?
cell surface membrane
The protective covering that allows materials to move into and out of a cell is the?
The cell membrane is the barrier that controls what substances enter and leave a cell.
