Question

Which plant is used for demonstrating plasmolysis in the laboratory?

• A. Tropaeolum
• B. Impatiens balsam
• C. Tradescantia
• D. All of the above

Answer 1

The correct option is C Tradescantia

Plasmolysis is the process in which cells lose water in a hypertonic solution.

Plasmolysis only occurs in extreme conditions and rarely happens in nature. It is induced in the laboratory by immersing cells in strong saline or sugar (sucrose) solutions to cause exosmosis, often using Tradescantia, which has pink colored cell sap so that the process is clearly visible.

So, the correct answer is 'Tradescantia'
