Cell Transport Lesson

The picture is an example of _________________ .

• endocytosis

• diffusion

• osmosis

• active transport

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 

• Movements of substances through a membrane. 

• When molecules spread from High to Low concentration on their own. 

• When pressure pushes something through a membrane. 

Movement of materials through a vesicle into the cell that requires energy is 

• exocytosis

• endocytosis 

• osmosis 

• simple diffusion 

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

Cells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell membrane against the concentration gradient. How do these molecules get into the cell?

• passive transport by diffusion

• active transport using ATP 

• passive transport by osmosis

•  osmosis

The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called

• perforated

• semi-permeable

• non-conducive

• permeable

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

What is the main difference between passive and active transport?

• Passive transport requires energy; active transport does not require energy.

• Active transport requires energy; passive transport does not require energy.

• Both passive and active transport require energy

• Neither passive or active transport require energy.
