Cell Transport Practice quiz

What are the key characteristics of Passive transport?

answer No Energy is used. Movement goes from high --> Low Concentration. answer

What is diffusion?

Diffusion is a type of passive transport where particles move from high concentration to low concentration. Examples: Puff of perfume Smell of a camp fire These particles diffuse throughout the room/area. Answer

Fill out the chart on the next slide.

Type of Solution Particle concentration in solution in cytoplasm Where is there more water? Which way will water move? Hypotonic Hypertonic Isotonic

Type of Solution Particle concentration in solution in cytoplasm Where is there more water? Which way will water move? Hypotonic Low High Outside Inside Hypertonic Isotonic = In and out Equally.

What is Facilitated Diffusion?

Answer A type of Diffusion that uses a protein. No energy needed. High  Low Concentration. Answer

What are the key points of Active Transport?

Answer Uses Energy (ATP) Low --> High Concentration (against the concentration gradient) Answer

Give an example of active transport.
