Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following best describes the primary function of the cell membrane?
Production of ATP
Control of substance passage into and out of the cell
Storage of genetic material
Synthesis of proteins
2. 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:
Diffusion
Active transport
Osmosis
Facilitated diffusion
1. Active transport requires energy.
True
False
2. Diffusion involves the movement of molecules from an area of lower concentration to an area of higher concentration.
True
False
1. The cell membrane is made up of a bilayer.
2. When a cell is placed in a solution, water will move out of the cell, causing it to shrink.
3. transport moves substances against their concentration gradient.
1. Briefly explain the difference between passive transport and active transport.
2. Describe the structure of the cell membrane and explain how it contributes to its function as a selective barrier.
