Quiz on Solutions and Cell Membranes

What is the liquid portion of a solution called?

• Solute

• Solvent

• Mixture

• Compound

What is the substance dissolved in a solution called?

• Solvent

• Solute

• Mixture

• Compound

How do molecules move across cell membranes?

• Based on their size

• Based on their shape

• Based on their concentrations

• Based on their color

What does the term refer to in the context of solutes inside and outside the cell?

• The relationship between the concentrations of solutes

• The size of the solutes

• The color of the solutes

• The shape of the solutes

What is passive transport?

• Movement that requires energy

• Movement that does not require energy

• Movement of solutes against a concentration gradient

• Movement of water using energy

What is diffusion?

• Movement of water across a membrane

• Movement of a solute from low to high concentration

• Spontaneous movement of a solute from high to low concentration

• Movement of a solute using energy

What is osmosis?

• Active transport of solutes

• Passive diffusion of water across a membrane

• Movement of water using energy

• Movement of solutes across a membrane

During osmosis, water flows from areas of:

• Lower solute concentration to higher solute concentration

• Higher solute concentration to lower solute concentration

• Equal solute concentration to equal solute concentration

• No solute concentration to high solute concentration

What happens to plant and animal cells when placed in freshwater?

• Both cells burst

• Both cells remain unchanged

• Plant cells swell, animal cells burst

• Plant cells burst, animal cells swell

What is the main function of active transport in cells?

• To use energy to transport molecules across a membrane

• To allow molecules to passively diffuse across a membrane

• To create energy within the cell

• To break down molecules for energy
