Turgidity and Flaccidity
Advertisements
Solution
| Turgidity | Flaccidity | ||
| 1. | It is the state of a cell in which the cell cannot accommodate any more water and is fully distended. | 1. | It is the condition in which the cell content is shrunken and the cell is not tight. |
| 2. | The availability of sufficient water causing the cells to become charged with water with its walls in a state of tension making the cells rigid and stretched. | 2. | The unavailability of sufficient water causes the cells to become weak and soft due to decreased turgor pressure. |
| 3. | This condition causes wilting in plants. | 3. | This condition makes plants stiff and erect. |
