cell transport

What is diffusion?

• when molecules move from a low concentration to a high concentration

• when molecules move from a high concentration to a low concentration

• when molecules do not move in or out of the cell

• when molecules cause water to freeze in place

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

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

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

 If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is _______ compared to the cell.

• hypertonic
• hypotonic
• isotonic

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

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

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

In a solution, salt is considered the _______.

• solvent
• solute
• solution
