Dive into the realm of cell transport with our comprehensive Cell Transport Worksheet Answer Key PDF. This meticulously crafted resource provides a profound understanding of the fundamental mechanisms governing the movement of substances across cell membranes, empowering educators and students alike to delve into the intricacies of cellular processes.
Within this worksheet, you will embark on a journey through the diverse types of cell transport, including passive and active transport, exploring real-world examples that illuminate the significance of these processes in maintaining cellular homeostasis and life itself.
Introduction to Cell Transport
Cell transport refers to the movement of molecules across the cell membrane, the boundary that separates the cell from its surroundings. This process is essential for the cell to maintain its internal environment and to exchange materials with its surroundings.
There are two main types of cell transport: passive and active.
Passive transport is the movement of molecules across the cell membrane without the input of energy. This type of transport occurs when there is a difference in concentration of a molecule across the membrane, and the molecules move from an area of high concentration to an area of low concentration.
Examples of passive transport include diffusion and osmosis.
Active transport is the movement of molecules across the cell membrane against a concentration gradient, requiring the input of energy. This type of transport is used to move molecules from an area of low concentration to an area of high concentration.
Examples of active transport include the sodium-potassium pump and the calcium pump.
Worksheet Overview

Answer Key Analysis
| Question | Correct Answer | Student Answer | Feedback |
|---|---|---|---|
| What is cell transport? | The movement of molecules across the cell membrane | The movement of molecules into the cell | The student’s answer is partially correct. Cell transport involves the movement of molecules across the cell membrane, both into and out of the cell. |
| What are the two main types of cell transport? | Passive transport and active transport | Diffusion and osmosis | The student’s answer is incorrect. Diffusion and osmosis are both types of passive transport. |
| Give an example of passive transport. | Diffusion of oxygen into the cell | Diffusion of oxygen out of the cell | The student’s answer is incorrect. Diffusion of oxygen into the cell is an example of passive transport. |
| Give an example of active transport. | Sodium-potassium pump | Calcium pump | The student’s answer is correct. The sodium-potassium pump and the calcium pump are both examples of active transport. |
