osmotic scenarios

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Permeable means

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

 An animal cell placed in a hypertonic (salty) solution will

• Stay the same
• Shrink- get smaller
• Swell- get bigger

Which way will the water molecules 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.
• Into the cell, so the cell swells.

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• There is no water

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• The water is a lie

What happens if someone gives you a 90% salt saline drip?

• Your cells will shrivel and you'll die
• Your cells will swell and you'll die
• Nah you'll be fine.

If the dots represent sugar which is more concentrated

• Inside the cell

• Outside the cell

• Neither they are equal (equilibrium)

If the dots represent sugar, what direction will water flow?

• Into the cell

• Out of the cell

• Into and out equally (equilibrium)
