Which of the following is the BEST definition for passive transport?

• Movement of substances through a cell membrane from a high to low concentration without the use of energy

• Movement of substances through a cell membrane from a low to high concentration requiring the use of energy

• Movement of substances through a cell membrane from a low to high concentration without the use of energy

• Movement of substance through a cell membrane from a high to low concentration requiring the use of energy

Select the correct definition for "Osmosis":

• A molecule is too large to pass through a cell membrane and therefore uses a transport protein

• The movement of substances from a low to high concentration; cell energy is used

• The movement of water from a high to low concentration through a selectively permeable membrane

• The movement of substances from a high to low concentration
