Cell Transport STAAR

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 happens to the cell membrane during exocytosis?

• Molecules pass directly through the phospholipids

• A vesicle fuses with the membrane and releases its contents out of the cell.

• Molecules use a transport protein to enter the cell.

• Water flows towards the higher solute concentration side of the membrane.

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

Why do cells change in size and shape in different concentration solutions?

• The cells are consuming energy.

• The cells are absorbing nutrients from the solution.

• Water is entering or leaving the cells.

• The cells are undergoing mitosis.
