Question

name _ date _ cell membrane bellringer label the following parts (not all the letters get used): cholesterol phospholipid protein channel phospholipid bilayer carbohydrate chain match the parts above to the correct function: double layers of special lipids that make up the cell membrane specialized lipid with a hydrophobic tail and a hydrophilic head molecule that provides structure and allows certain molecules to cross the cell membrane molecule that acts as an id badge for cells molecule that helps the cell membrane stay fluid and flexible why is the cell membrane known as a fluid mosaic? _

Explanation:

Cholesterol helps maintain membrane fluidity. Phospholipids form the bilayer with hydrophilic heads and hydrophobic tails. Protein channels facilitate molecule passage. Carbohydrate chains act as cell - ID markers. The cell membrane is a fluid mosaic because its components can move laterally and it is composed of a variety of molecules like lipids, proteins, and carbohydrates.

Answer:

• cholesterol: E (assuming E is the correct - labeled cholesterol in the diagram)
• phospholipid: A (assuming A represents a single phospholipid)
• protein channel: G
• phospholipid bilayer: The double - layer structure made up of A - like phospholipids
• carbohydrate chain: D
• double layers of special lipids that make up the cell membrane: phospholipid bilayer
• specialized lipid with a hydrophobic tail and a hydrophilic head: phospholipid
• molecule that provides structure and allows certain molecules to cross the cell membrane: protein channel
• molecule that acts as an ID badge for cells: carbohydrate chain
• molecule that helps the cell membrane stay fluid: cholesterol
• Why is the cell membrane known as a fluid mosaic?: Because its components can move laterally and it is composed of a variety of molecules such as lipids, proteins, and carbohydrates.
