It also enables cells to create turgor pressure, or the pressure of cell contents against the cell wall. The cell wall of plant cells covers the plasma membrane and offers tensile strength and resistance to mechanical and osmotic stress. The three layers are the middle lamella, primary cell wall, and secondary cell walls. In many plants, the cell wall is composed primarily of cellulose and has three layers. ![]() Based on the structure and types of carbohydrates in the glycocalyx, your body can recognize cells and determine if they should be there or not.The cell wall’s primary functions are to provide structure, support, and protection to the cell. It can provide cushioning and protection for the plasma membrane, and it is also important in cell recognition. The glycocalyx of a cell has many functions. ![]() Together these carbohydrates form the glycocalyx. That is, they are only found on the extracellular side of a cell membrane. ![]() Carbohydrates, or sugars, are sometimes found attached to proteins or lipids on the outside of a cell membrane. Such cell adhesion molecules have now been identified in several cellular systems. Cell recognition is defined as an active process giving rise to a specific response.Ĭell adhesion is a good example of cell recognition when it can be demonstrated that the adhesion is mediated by molecules having specific binding properties. Detailed Solution for Test: Cell Wall, Cell Membrane & Glycocalyx - Question 17Ĭarbohydrates which are present in the cell membrane take part in cell recognition. ![]()
