Because of their malleability, they are able to complement – not compete with – existing architecture and the natural environment. Tensile structural systems are low-maintenance and provide year-round protection from the elements. Most often used for roofs and canopies, tensile structures are capable of creating unique private and public spaces. Made of coated PES, ETFE, PTFE, or PTFE coated fiberglass, the tensile membranes can span large distances and take on a variety of shapes. Tensile membranes carry tension with no compression or bending, supported by a lightweight structural system. In fact, they have a cell wall outside of them, and that cell wall is much tougher and is structurally more sound than a plasma membrane is.Tensile membrane structures and tensile building envelopes are thin-shell structures. Now, there are different plants and different microbes, such as bacteria and algae, which have different protective mechanisms.
That's different from certain other membranes from within the cell. And there are different types of plasma membranes in different types of cells, and the plasma membrane has in it in general a lot of cholesterol as its lipid component. The cell membrane also provides some structural support for a cell. And those proteins which stick outside of the plasma membrane will allow for one cell to interact with another cell. Those proteins can be glycoproteins, meaning there's a sugar and a protein moiety, or they could be lipid proteins, meaning that there's a fat and a protein. Another is that the membrane of the cell, which would be the plasma membrane, will have proteins on it which interact with other cells. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. The plasma membrane, or the cell membrane, provides protection for a cell.
