FAQs on Plasmolysis Video Lecture - NEET
| 1. What is plasmolysis? |  |
Ans. Plasmolysis is a process that occurs in plant cells when they are placed in a hypertonic solution, causing water to move out of the cell and the cell membrane to shrink away from the cell wall.
| 2. What are the causes of plasmolysis? | |
Ans. Plasmolysis can be caused by various factors such as excessive salt concentration in the external environment, drought conditions, or the presence of osmotically active substances.
| 3. How does plasmolysis affect plant cells? | |
Ans. Plasmolysis can have detrimental effects on plant cells. As water moves out of the cell, the cell membrane shrinks away from the cell wall, leading to a loss of turgor pressure and causing the plant to wilt. This can impair the cell's ability to perform essential functions and can ultimately lead to cell death.
| 4. Can plasmolysis be reversed? | |
Ans. In some cases, plasmolysis can be reversed if the plant cell is placed in a hypotonic solution, where water moves back into the cell and restores its turgidity. However, if the plasmolysis has caused irreversible damage to the cell, it may not be able to recover fully.
| 5. What is the significance of studying plasmolysis? | |
Ans. Studying plasmolysis is important in understanding how plant cells respond to changes in their external environment. It provides insights into the mechanisms of water movement and the effects of osmotic stress on plants. This knowledge can be applied in various fields such as agriculture, plant physiology, and biotechnology to develop strategies for improving plant resilience and productivity in challenging conditions.
