1. Which component of the cell membrane is primarily responsible for its fluidity?

2. Which type of membrane protein is involved in active transport?

3. The cell membrane is described as a   model, indicating its dynamic nature and the presence of various components.

4.   is the movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

5. Glycocalyx is formed by the carbohydrate chains of   and   on the outer surface of the cell membrane.

6. Facilitated diffusion requires energy in the form of ATP.

7. The hydrophobic tails of phospholipids face outward towards the aqueous environment.

8. Describe the main functions of the cell membrane.

9. Explain the difference between passive and active transport across the cell membrane.
