Read each question carefully and answer to the best of your ability. This worksheet covers various aspects of cellular transport, including passive and active mechanisms.
1. Which of the following best describes the primary function of the cell membrane?
To produce energy for the cell.
To control what enters and leaves the cell.
To store genetic material.
To synthesize proteins.
2. Which type of transport requires the cell to expend energy?
Simple diffusion
Osmosis
Facilitated diffusion
Active transport
1. The movement of water across a selectively permeable membrane is called .
2. Large molecules are transported out of the cell by a process called .
3. The is composed of a phospholipid bilayer with embedded proteins.
1. Diffusion is the movement of molecules from an area of lower concentration to an area of higher concentration.
True
