Some of the proteins and lipids do control movement of materials into and out of the cell.
Some of the proteins and lipids do control movement of materials into and out of the cell.
A cell membrane surrounds all cells and controls the movement of substances.
Proteins such as transporters, channels, and pumps are the main molecules that help control the movement of substances through cell membranes. These proteins facilitate the selective transport of ions, molecules, and other substances into and out of cells, maintaining proper cellular function. Additionally, phospholipids in the membrane also play a role in regulating the movement of substances across the cell membrane.
The plant cell's shape is maintained by its rigid cell wall made of cellulose. The movement of materials into and out of the cell is controlled by the cell membrane, which acts as a barrier and selectively regulates the passage of substances through active and passive processes.
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.

protein channels aid the movement of substances into and out of the cell.
The cell membrane contains protein channels and transporters that regulate the movement of materials in and out of the cell. These channels and transporters control the passage of specific substances into and out of the cell. The cell membrane itself does not have "tiny holes" but rather selective protein structures that facilitate the transport of molecules.
Cell membranes are selectively permeable, meaning they control what substances can pass through based on size and charge. This is achieved through membrane proteins and channels that facilitate the movement of specific molecules in and out of the cell. Additionally, active transport processes such as pumps and vesicle transport mechanisms also help regulate the movement of substances across the cell membrane.
