Cell Transport Quiz review

As a result of diffusion, the concentration of many types of substances

• always remains greater inside a membrane.

• eventually becomes balanced on both sides of a membrane.

• always remains greater on the outside of a membrane.

• becomes imbalanced on both sides of a membrane.

Diffusion takes place

• only through a lipid bilayer membrane.

• from an area of low concentration to an area of high concentration.

• 
  only in liquids.

• from an area of high concentration to an area of low concentration.

The solution in beaker A would : Hint: remember when there is more solute there is less water and where there is less solute, there is more water. Osmosis goes from a high water concentration to a low water concentration.

• hypertonic

• hypotonic

• 
  isotonic

• 
  plasmoslysis

The cell in beaker B would be. Hint: remember when there is more solute there is less water and where there is less solute, there is more water. Osmosis goes from a high water concentration to a low water concentration.

• 
  hypertonic

• hypotonic

• 
  isotonic

• 
  neutral

The solution in beaker C would be :Hint: remember when there is more solute there is less water and where there is less solute, there is more water. Osmosis goes from a high water concentration to a low water concentration.

• hypertonic

• hypotonic

• isotonic

• neutral

The dispersal of food coloring in a beaker of water is an example of

• deposition

• diffusion

• active transport

Which of the following does not expend energy?

• diffusion

• exocytosis

• active transport

• protein pump

The sodium potassium pump is a form of active transport. This means _______________________________ is required

• glucose

• ATP( energy)

• water

• oxygen

The process by which water passes into or out of a cell is called

• 
  solubility

• selective transport

• osmosis

• endocytosis

The ability for a cell membrane to allow certain things in and out allows it to maintain its

• evolution

• 
  homeostasis

• integrity

• 
  independence
