When a gummy bear shrinks, is that considered hypertonic or hypotonic?

The Effect of Osmosis on Gummy Bears

Gummy bears are a popular candy treat enjoyed by many people, both young and old. But have you ever wondered what happens to a gummy bear when it is placed in different solutions? Let's explore the fascinating world of osmosis and find out whether a shrinking gummy bear is considered hypertonic or hypotonic.

Osmosis and Water Movement

Osmosis is the movement of water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. This process plays a crucial role in maintaining the balance of water in living organisms.

Hypertonic or Hypotonic?

When a gummy bear is placed in a hypertonic solution, such as a salt solution, the concentration of solutes outside the bear is higher than inside. As a result, water molecules move out of the bear, causing it to shrink in mass and volume. This shrinkage is due to the process of osmosis, where water flows from a region of lower solute concentration (inside the bear) to a region of higher solute concentration (outside the bear).

On the other hand, when a gummy bear is placed in a hypotonic solution, such as pure water, the concentration of solutes outside the bear is lower than inside. In this case, water molecules enter the bear, causing it to expand in size and volume. The gummy bear absorbs water through osmosis, leading to an increase in mass and volume.

Conclusion

So, when a gummy bear shrinks, it is considered hypertonic. The loss of water from the bear to the hypertonic solution results in the bear becoming smaller in size and volume. Understanding the effects of osmosis on gummy bears can provide insights into how cells and organisms maintain water balance in different environments.
