Osmosis

Water flows across a cell membrane from where it is -

• least pure to purest

• saltiest to least salty

• purest to least pure

• water does not flow across the membrane

What term is used to describe when two solutions have reached a balanced state?

• Hypotonic

• Tonicity

• Hypertonic

• Equilibrium

How are osmosis and diffusion similar processes?

• A both move solute molecules

• both move water molecules

• they move low to high concentrations

• both move high to low concentrations

Active transport goes against the concentration gradient. What does that mean?

• High to Low

• Low to High

A cell has 80% water 20% solute, the surrounding solution has 60% water and 40% solute. What type of solution is this?

• Hypertonic

• Isotonic

• Hypotonic

• Equilibrium

When placed in a solution of 30% water 70% salt, what would happen to a cell that is 70% water?

• it will take in salt and swell

• it will take in water and swell

• it will lose water and shrink

• it will remain the same size

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

The cell below is in a _____________ solution.

• Hypertonic
• Hypotonic
• Isotonic
