The correct Answer is:
To solve the question regarding the stages of plasmolysis, we need to analyze each statement given and determine which stage of plasmolysis it refers to. Here’s a step-by-step breakdown: ### Step 1: Understand Plasmolysis Plasmolysis is the process where the protoplast (the living part of the cell) shrinks away from the cell wall due to the loss of water when the cell is placed in a hypertonic solution. ### Step 2: Analyze the Statements 1. **Statement (i)**: "First stage of plasmolysis, when osmotic concentration of cell sap is just equivalent to that of external solution." - This describes **Limiting Plasmolysis**, where the cell is flaccid, and the osmotic pressure inside the cell equals that outside. 2. **Statement (ii)**: "Protoplast withdraws itself from corners of the cell wall." - This refers to **Incipient Plasmolysis**, which occurs when the protoplast begins to shrink but is still attached to the cell wall at some points. 3. **Statement (iii)**: "Protoplast gets detached from the cell wall and attains a spherical shape." - This describes **Evident Plasmolysis**, where the protoplast has completely detached from the cell wall and takes on a spherical shape due to the loss of turgor pressure. ### Step 3: Identify the Correct Option The statements correspond to the following stages of plasmolysis: - (i) Limiting Plasmolysis - (ii) Incipient Plasmolysis - (iii) Evident Plasmolysis Thus, the correct option regarding these statements is that they represent the stages of plasmolysis in the order of Limiting, Incipient, and Evident plasmolysis. ### Final Answer The correct option is: **Limiting Plasmolysis, Incipient Plasmolysis, and Evident Plasmolysis.** ---
