Cell transport

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.
