A student put a few drops of lemon juice into an uninflated balloon.The student tied a knot in the balloon, placed it in a shoe box, and covered it with a lid. The following day, the student opened the box and was able to smell lemon in the box. Through what process were molecules able to pass through the balloon?

• respiration
• fermentation
• osmosis
• diffusion

Diffusion is the movement of molecules from an area of _____ concentration to an ______ concentration

• high, low

• low, high

• low, low

• high, high

The picture below is an example of _________________.

• osmosis

• isotonic

• diffusion

• active transport

When does diffusion stop?

• After a day and a night.

• When the particles are evenly spread out.

• When there are no particles left.

• When all the particles leave the system.

During osmosis ___________.

• water moves from high to low concentrations

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

Which picture illustrates diffusion?

• 
• 
• 
• 

What does a cell needs to transport particles by ACTIVE transport?

• Sun

• Wind

• Energy

• Channels

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

• diffusion

• equilibrium

• confusion

If there is 5% water inside a cell and 5% water outside a cell...

• more water will move inside the cell

• more water will move outside the cell

• there will be no movement of water cells
