What word is used to describe plant cells placed in a hypotonic solution?

Answers

Answer:

The answer is Plasmolysis

The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

What is a Hypotonic solution?

A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.

According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.

Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
