उत्तर
| Sr. No. | Turgid | Flaccid |
| (i) | It occurs when the cell is placed in hypotonic solution. | It occurs when the cell is placed in a hypertonic solution. |
| (ii) | It occurs due to endosmosis. | It occurs due to exosmosis. |
| (iii) | The condition in which the cell wall is rigid and stretched due to the absorption of water is called turgidity. | The state in which the cell content is shrunken is called flaccidity. |
| (iv) | It is the state of a cell in which the cell wall is rigid and stretched by an increase in the volume of vacuoles due to the absorption of water. | It is the condition in which the cell content is shrunken and the cell is not tight. |
| (v) | Water moves into the cell. | Water moves out of the cell. |
