cell transport 2

Active transport moves materials in which direction?

• From high to low

• From low to high

• In either direction

What type of transport is this?

• Exocytosis

• Active Transport

• Simple Diffusion

• Facilitated Diffusion

In which solution will water move into a cell?

• Equilibrium

• Isotonic

• Hypertonic

• Hypotonic

In passive transport, molecules move from an area of __________ concentration to an area of __________ concentration.

• active, passive

• water, salt

• low, high

• high, low

Click on the ACTIVE transport examples below:

• Facilitated Diffusion

• Endocytosis

• Exocytosis

• protein pumps

• Osmosis

What type of cell structure is used during endocytosis and exocytosis?

• Vacuole

• Golgi Body

• Vesicle

• Endoplasmic Reticulum

What is the biggest difference between active and passive transport across the membrane?

• Passive moves materials from low to high

• Active uses ATP energy; passive does not

• Active moves materials from high to low

• Passive uses ATP energy; active does not

Which of the following is an example of active transport?

• Oxygen diffusing across the membrane of a red blood cell

• Water leaving a cell that is placed in a hypertonic solution

• Plant roots taking up mineral into root cells with an already high concentration of minerals

• Glucose being moved across the cell membrane from a high concentration to a low concentration

What type of transport is this?

• Simple Diffusion

• Sodium-Potassium Pump

• Endocytosis

• Exocytosis

What type of transport is this? (HINT: there is no ATP in this picture & pay close attention to the movement of particles)

• Simple diffusion

• Osmosis

• Facilitated Diffusion

• Active Transport
