Cell Transport Test

Which picture shows the process of endocytosis?

• 
• 
• 
• 

Molecules moving from high concentration areas to low concentration areas is -

• active transport

• passive transport

• bulk transport

What type of movement is passive and the molecule needs the helps of a membrane protein to move through the cell membrane?

• Facilitated diffusion

• Simple diffusion

• Exocytosis

• Osmosis

What are the main components of the cell membrane?

• DNA, transport proteins, sugar

• Carbohydrates, phospholipids, water

• Phospholipids, transport proteins, cholesterol

• Proteins, water, DNA

What type of solution will cause a cell to lose water and shrivel up?

• Hypotonic

• Isotonic

• Pure solution

• Hypertonic

The movement of water is called -

• Simple diffusion

• Osmosis

• Active transport

• Endocytosis

Which of the following types of cell transport uses energy?

• Passive transport

• Active transport

What is required to move molecules from low concentration areas to high concentration areas?

• ATP

• Water

• Salt

• Carbohydrates

What does a salty solution do to cells?

• Puncture holes in their cell membranes

• Cause water to flow into the cells

• Removes water from the cells

• Makes the cells burst

What does selectively permeable mean?

• That all molecules are allowed to enter

• That some molecules are allowed to enter

• The only water is allowed to enter

• That no molecules are allowed to enter
