Cell Transportation

What is the movement of molecules from an area of higher concentration to an area of lower concentration called.

• Concentration

• Facilitated Diffusion

• Osmosis

• Diffusion

What is Active Transport?

• Movement of molecules from no concentration to high concentration. Requires no energy

• Movement of molecules from low to high concentration. Requires Energy

• Movement of molecules from high to low concentration. Requires no Energy

• Movement of proteins within the cell.

Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

Diffusion is the movement of molecules from an area of _____ concentration to an ______ concentration

• High, low

• Low, high

• Low, low

• High, high

If there is more oxygen in the blood than in an organ, which direction would the oxygen move?

• Out of the blood

• Into the blood

The picture below is an example of _________________.

• osmosis

• isotonic

• diffusion

• active transport

Osmosis is the movement of _____ across a membrane.

• food

• energy

• oxygen

• water

During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

Permeable means

• things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.

• Out of the cell, so the cell swells.

• Into the cell, so the cell shrinks.

• Into the cell, so the cell swells.
