Cell Transport Practice and Review

Correctly label this diagram.

a

Passive Transport

Active Transport

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

Name the process illustrated in the diagram.

The movement of water from an area of high concentration to low concentration is (a)   . When diffusion requires the help of transport proteins it is called (b)   diffusion.

• osmosis
• facilitated
• diffusion
• sodium potassium pump
• endocytosis

A root cell may continue to absorb minerals even though the concentration of the minerals is greater inside the cell than in the soil. This absorption is accomplished mainly by —

• active transport

• passive transport

• diffusion

• osmosis

Which process requires cellular energy (ATP)?

• Active transport

• Passive transport

• Facilitated diffusion

• Osmosis

Identify the types of solutions these cells were placed in.

An experiment was done using gummy bears to show the movement of water in different solute concentrations. If a gummy bear was placed in a solute concentration that was higher outside the gummy bear than inside the gummy, select the image that demonstrates the effects that occurred to the gummy bear?
