The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
Cell membrane
The nucleus, specifically through its regulation of gene expression, controls the production of proteins that are involved in cell movement. Additionally, the cytoskeleton plays a key role in cell movement by providing structural support and facilitating movement of organelles.
phospholipid bilayer, which consists of two layers of phospholipid molecules. It controls the movement of substances in and out of the cell, providing a barrier that separates the internal and external environments of the cell.
The main function of the cell membrane is to regulate the movement of substances in and out of the cell. It acts as a barrier that allows essential molecules to enter the cell while keeping harmful substances out. Additionally, cell membranes also help maintain the cell's shape and provide structural support.
The cell membrane, specifically through integral membrane proteins, controls the intake of nutrients and movement in and out of the cell. The cytoskeleton within the cell is responsible for cell movement by providing structure and support for the cell.

The cell membrane controls what goes in and out of the cell. It acts as a barrier and regulates the passage of molecules such as nutrients and waste products. Additionally, specific proteins in the cell membrane help facilitate the movement of certain substances across it.

The semi-permeable part of the cell would be the cell membrane, which allows some molecules (water, in particular) to pass freely through but restricts the movement of other molecules (such as proteins and enzymes).
The part of the cell is called the nuclear envelope, which consists of two lipid bilayer membranes that enclose the nucleus. It controls the movement of molecules in and out of the nucleus, regulating communication between the nucleus and the cytoplasm.
The cell membrane is reposnible for allowing what substances can enter and leave a cell, this happens by different methods of transport for instance "active transport" in plants. The phospholipid bilayer containing cholesterol, proteins and carbohydrates, also helps in allowing which substances to pass.
The Nucleus
The cell membrane in an animal cell can be compared to human skin, as it serves as a protective barrier that regulates the movement of substances in and out of the cell, similar to how the skin protects the body and controls the passage of molecules.
