Membrane fluidity results from lateral movement of proteins within the quasi-fluid lipid bilayer. This property is important in cell growth, formation of intercellular junctions, secretion, endocytosis and cell division.

In the fluid mosaic model, the quasi-fluid nature of the lipid bilayer allows proteins to move laterally within it. This movement is measured as membrane fluidity and is important in processes such as secretion, endocytosis and cell division.

Increasing polyunsaturated fatty acids correctly describes the effect or change asked about in this question. In Lipids without annotations, understanding cause-and-effect relationships is essential for predicting biological outcomes. Increasing polyunsaturated fatty acids occurs because of specific molecular interactions, thermodynamic principles, or regulatory mechanisms that govern this biological process. The other options (Increasing cholesterol content, Increasing saturated fatty acids, and Decreasing temperature) describe either opposite effects, effects that occur under different conditions, or changes associated with unrelated processes.
