Potato Osmosis Lab

The potato strip became soft as it

• lost water

• gained water

• gained and lost water equally

• none of these

Osmosis is the diffusion of ___________.

• gases
• glucose
• ions
• water

An isotonic solution will have ____________ concentration of water compared to another solution

• a greater

• less

• the same

When y=0 on your graph it meant that the potato strip

• shrink

• grow

• had no changes

In regards to water concentration, what is the significance of y equal to zero?

• It shows the concentration of external solution which is isotonic to the potato cells

• It shows the concentration of external solution which is hypertonic to the potato cells

• It shows the concentration of external solution which is hypotonic to the potato cells

If the potato core lost water then it must have been in a ____________ solution

• hypotonic 
• hypertonic
• isotonic
• none of these
