Cell Transport

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

Cells use energy to move materials across a membrane (low to high concentration) during

• Active transport.

• Passive transport.

• Diffusion.

• Osmosis.

If the sodium concentration inside of a cell is greater than outside the cell, how can a cell take in more sodium?

• osmosis
• diffusion
• active transport
• passive transport

When a cell forms a vesicle around unwanted particles and expels it OUT of the cell it is...

• Pinocytosis.

• Endocytosis.

• Phagocytosis.

• Exocytosis.

In this image, the cell is using which type of molecular transport?

• Osmosis
• Diffusion 
• Endocytosis
• Exocytosis

Facilitated diffusion is the movement of materials into and out of the cell...

• with the use of energy.

• with the use of proteins but no energy.

• by moving water.

• by using ATP.

The  movement of water from a high concentration to a low concentration is called...

• diffusion.

• osmosis.

• facilitated diffusion.

• active transport.

In this situation, where the solute is illustrated by red dots, predict if will water move into or out of the cell and how that will affect the cell.

• Water will move into the cell and the cell will expand.
• Water will move into the cell and the cell will shrink.
• Water will move out of the cell and the cell will expand.
• Water will move out of the cell and the cell will shrink.

Semi-permeable means to allow...

• all materials across the membrane.

• only some materials across the membrane.

• no material to cross the membrane.

• to allow only water across the membrane.
