If an elodea leave is place in pure distilled water, what will happen?
plus will this be isotonic or hypertonic or hypotonic solution.
If an Elodea leaf is placed in pure distilled water, a few things will happen. Let's first understand the concepts of isotonic, hypertonic, and hypotonic solutions.
An isotonic solution is one in which the solute concentration inside and outside the cell is equal. In this scenario, there will be no net movement of water molecules into or out of the Elodea leaf. The cell will remain in equilibrium, and there will be no visible changes.
A hypertonic solution is one in which the solute concentration outside the cell is higher than inside. In this case, water molecules will tend to move out of the Elodea leaf, causing it to shrink or shrivel.
A hypotonic solution is one in which the solute concentration outside the cell is lower than inside. If an Elodea leaf is placed in pure distilled water, which has no solutes, it can be considered a hypotonic solution. In this case, water molecules will move into the Elodea leaf to equalize the solute concentration inside and outside the cell. This will cause the cell to swell and become turgid.
So, in summary, when an Elodea leaf is placed in pure distilled water, it will become turgid as the water enters the cell, making it a hypotonic solution.
