The process in the model is __________ and it __________.

• Facilitated transport; needs energy

• Endocytosis; needs energy

• Exocytosis; does not need energy

• Cytoplasmic Streaming; needs a protein

In this image, the cell is using which type of molecular transport?

• Osmosis
• Diffusion 
• Endocytosis
• Exocytosis 

Human red blood cells contain 0.9% sodium chloride as a component of their cytoplasm. What would happen if an IV solution containing 3.5% sodium chloride is introduced into a person? 

• The red blood cell would get bigger and burst.

• The red blood cell would stay the same size.

• The red blood cell would shrink.

• The red blood cell would first loose water and then absorb water.

Students are observing particles moving against the concentration gradient in a lab investigation. Which type of transport are they observing?

• osmosis

• active Transport

• facilitated diffusion

• diffusion

This picture shows molecules of red dye that have moved. What is this type of movement called?

• Osmosis; the water molecules are moving from high concentration to low

• Diffusion; the dye molecules are moving from low to high concentration

• Diffusion; the dye molecules are moving from high to low concentration.

• Facilitated diffusion; because the molecules are moving through a protein channel.

This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
