Read each question carefully and provide the best answer. Refer to the provided cell membrane diagram for relevant questions.
1. Which component of the cell membrane is primarily responsible for its selective permeability?
Proteins
Carbohydrates
Phospholipid bilayer
Cholesterol
2. Which type of transport requires energy to move substances across the cell membrane against their concentration gradient?
Facilitated diffusion
Osmosis
Simple diffusion
Active transport
3. The movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration is called .
4. The fluid mosaic model describes the cell membrane as a flexible structure made of a with embedded proteins.
5. Diffusion is the net movement of particles from an area of lower concentration to an area of higher concentration.
True
False
6. Integral proteins are found only on the surface of the cell membrane.
True
False
7. Describe the role of phospholipids in the structure of the cell membrane.
8. Explain the difference between passive transport and active transport across the cell membrane.
