Eukaryotic Plasma Membrane Functions

Very Hard Biology Cell Structure And Function

The plasma membrane of eukaryotic cells is characterized by its fluid mosaic model, which describes how various components can move within the layer. This structure is crucial for protecting the cell and maintaining homeostasis. The membrane is primarily composed of phospholipids, proteins, cholesterol, and carbohydrates. Each component plays a specific role in the function of the membrane. Considering this complexity, which of the following statements accurately describes a function or characteristic of eukaryotic plasma membranes?

The plasma membrane is impermeable to all types of molecules.

Cholesterol molecules within the membrane increase fluidity at lower temperatures.

Proteins embedded in the membrane are static and cannot move laterally.

Carbohydrate chains on the membrane surface play a role in cell recognition.
