Osmosis and Membrane Transport Quiz

What is osmosis?

• Movement of solute molecules through a membrane

• Movement of solvent molecules through a membrane

• Movement of gases through a membrane

• Movement of solids through a membrane

What type of membrane does osmosis occur across?

• Impermeable membrane

• Semi-permeable membrane

• Fully permeable membrane

• Non-permeable membrane

In osmosis, solvent moves to the side with what concentration of solutes?

• Lower concentration of solutes

• Higher concentration of solutes

• Equal concentration of solutes

• No solutes

What is the main way water gets in and out of cells?

• Diffusion

• Active transport

• Osmosis

• Filtration

What type of transport uses energy and is selective?

• Passive transport

• Active transport

• Facilitated diffusion

• Simple diffusion

What does the permeability of a membrane depend on?

• Temperature

• Solubility, charge, or chemistry

• Pressure

• Light

What is the function of the cell membrane's ports or gateways?

• Block all molecules

• Allow all molecules

• Get certain macromolecules through

• Store energy

What is the role of the phospholipid bilayer in osmosis?

• Blocks all molecules

• Allows water molecules to diffuse

• Synthesizes proteins

• Stores carbohydrates

What occurs when a cell is submerged in freshwater?

• Water molecules move out of the cell

• Water molecules move into the cell

• Solute molecules move into the cell

• Solute molecules move out of the cell

What is the result when the membrane has a volume of pure water on both sides?

• Water flows into the cell

• Water flows out of the cell

• No net flow of water

• Solute flows into the cell
