Cell Transport Quiz

The picture is an example of...

• active tranport

• passive transport

• diffusion

• osmosis

What type of transport is this?

• Endocytosis

• Diffusion

• Exocytosis

• Osmosis

Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water

The roots of a plant contain a high concentration of minerals and the soil contains a lower concentration.  The roots absorb minerals from the soil.  This is an example of

• passive transport.

• active transport.

• diffusion

• osmosis

What is diffusion?

• The movement of water molecules from an area of high concentration to an area of low concentration.

• The movement of solute molecules from an area of low concentration to an area of high concentration.

• The movement of solute molecules from an area of high concentration to an area of low concentration.

• The active transport of molecules against the concentration gradient.

What is osmosis?

• The movement of solute molecules across a semipermeable membrane.

• The movement of water molecules from an area of low solute concentration to an area of high solute concentration across a semipermeable membrane.

• The active transport of water molecules against the concentration gradient.

• The movement of water molecules from an area of high solute concentration to an area of low solute concentration across a semipermeable membrane.

Which of the following is an example of active transport?

• Diffusion of oxygen from the lungs into the bloodstream.

• Osmosis of water into the root cells of a plant.

• The sodium-potassium pump moving ions against their concentration gradient.

• The diffusion of carbon dioxide from cells into the bloodstream.

What is passive transport?

• The movement of molecules without the use of energy.

• The movement of molecules that requires energy.

• The transport of molecules against the concentration gradient.

• The transport of molecules in large quantities through vesicles.

What is endocytosis?

• The process of expelling materials from the cell into the extracellular fluid.

• The movement of molecules from an area of high concentration to an area of low concentration.

• The process of a cell engulfing material from the extracellular environment.

• The active transport of ions across the cell membrane.

What is exocytosis?

• The process of a cell taking in material from the extracellular environment.

• The movement of water molecules from an area of high concentration to an area of low concentration.

• The process of expelling materials from the cell into the extracellular fluid.

• The active transport of molecules against the concentration gradient.
