Solution
The correct option is D Tradescantia
Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. Plasmolysis is one of the results of osmosis and occurs very rarely in nature, but it happens in some extreme conditions.
The plasmolysis can be induced in the laboratory by immersing living cell in a strong salt solution or sugar solution to lose water from the cell. Normally, Rheo or Tradescantia plant epidermal cells are used for experiment because they have coloured cell sap which can be clearly visible.
Thus, the correct answer is option (D).
