Passive and Active Transport

Osmosis is the movement of _____ across a membrane.

• water
• energy
• oxygen

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

Permeable means

• it is permanent
• the concentration levels are different
• things can pass through

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

In the given scenario what will happen to the organism: salt is poured onto eggplant.

• Water will move out of the eggplant cells and the cells will swell.
• Water will move out of the eggplant cells and the cells will shrink.
• Water will move into the eggplant cells and the cells will swell.

Which way will the water molecules in the image move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes

• water to move into the cell.
• water to move out of the cell.
• solutes to move into the cell.
