Cell Transport Review

Permeable means

• things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

What is the definition of selectively permeable?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.

• The movement of materials through (or across) the cell membrane

• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

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

What are the two types of cell transport?

• Passive and Active

• Active and Facilitated

• Passive and Facilitated

• None of the above

In passive transport, substances move across the cell membrane ________ the concentration gradient

• AGAINST

• ALONG

• WITH

• BETWEEN
