The cell membrane regulates what enters and leaves a cell. It is selectively permeable, allowing certain substances to pass through while blocking others. Transport proteins in the membrane help facilitate the movement of specific molecules across the cell membrane.
The form you are describing is a type of membrane-bound organelle known as a vesicle. Vesicles can break off from the cell membrane to transport substances within the cell or to the cell's exterior.
by diffusion and osmosis

The cell membrane is a semi-permeable barrier that surrounds the cell, controlling the passage of substances in and out of the cell. It is made up of a phospholipid bilayer with embedded proteins that help maintain the cell's structure and function. The membrane also plays a role in cell signaling and communication.
They help control what enters and leaves the cells.
The cell membrane forms a boundary between the inside and outside of the cell. It is very flexible.
The Cell Membrane helps the plant cell by guarding any viruses that come near it.
controlling what comes in and out of the cell! :D

They help move material in and out of the cell.
Membrane bio- genesis is the process, when some proteins and lipids (produced in SER)help in building the cell membrane, inside a cell.
It lets authorized objects come in and out of the cell to protect it
Cell Membrane
They are called porins and help in the transfer of materials in and out of the cell.
