The structure around the outside of a plant cell that prevents it from rupturing due to too much water is the cell wall.

Here's why:

* Rigid Structure: The cell wall is made of cellulose, a strong and rigid material. This structure provides support and resistance to internal pressure.

* Turgor Pressure: When a plant cell takes in water, it creates pressure against the cell wall, known as turgor pressure. The cell wall can withstand this pressure without breaking.

* Flexible Nature: While strong, the cell wall also has some flexibility. This allows the cell to expand to a certain degree, accommodating the increased water intake.
