Having a higher surface area-to-volume ratio, such as with microvilli or folded membranes, can make simple diffusion more efficient because it provides more space for molecules to pass through the membrane and increases the rate of diffusion.
Selective Permeability
permeability
It is the plasma membrane of a cell. The plasma membrane is a phospolipid bilayer, but because the phospsolipids are amphipathic, and because the lipid tails of each are turned into one another it is considered a trilamina. Hydrophilic Head of the inner layer + lipid tails of each layer + Hydrophilic Head of the outer layer.

Proteins are a structural feature of a cell membrane that are missing from a liposome. Liposomes are artificial vesicles composed of a phospholipid bilayer and do not contain the diverse array of proteins found in natural cell membranes.
One structural feature that is not important on the surface membrane of an animal cell is the presence of a cell wall. Animal cells lack a cell wall, unlike plant cells which have a rigid cell wall for structural support and protection.
The rapid widespread diffusion of a feature or trend throughout a population
Glycoproteins and glycolipids are structural features on the surface of the plasma membrane that allow cells to recognize one another. These molecules can act as cell identifiers by creating unique patterns that other cells can identify and respond to.
The absence of a nuclear membrane in prokaryotic cells would have needed to change in order for endosymbionts to be acquired by eukaryotic cells. This structural feature prevents direct incorporation of free-living prokaryotes into the cell.

Well the alveolus has a large surface area that helps with diffusion rate. It also have thin walls and shape. Done by: Candy
The alveoli have extremely thin walls composed of a single layer of epithelial cells, which provides a short diffusion pathway for gases. This thinness allows for efficient gas exchange, as oxygen can quickly diffuse into the blood and carbon dioxide can diffuse out. Additionally, the large surface area of the alveoli, due to their numerous and clustered structure, further facilitates rapid diffusion.
