Quick Answer: What Is The Definition Of Plasmolysis In Biology?

Plasmolysis is a typical response of plant cells exposed to hyperosmotic stress. The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole. Plasmolysis is reversible (deplasmolysis) and characteristic to living plant cells.

What is a plasmolysis in biology?

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.

What is plasmolysis in biology class 9?

Plasmolysis is defined as the process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell. The word Plasmolysis was generally derived from a Latin and Greek word plasma – The mould and lusis meaning loosening.

What is plasmolysis with example?

When a living plant cell loses water through osmosis, there is shrinkage or contraction of the contents of cell away from the cell wall. This is known as plasmolysis. Example – Shrinkage of vegetables in hypertonic conditions.

What is plasmolysis Class 11?

The process in which water moves out of the cell, and the cell membrane of a plant cell shrinks away from its cell wall, is called plasmolysis.

What is plasmolysis short answer?

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

What is Exosmosis in biology?

Exosmosis is the movement of water outside the cells when a cell is placed in a hypertonic solution. The cell becomes flaccid by the movement of water outside.

What is plasmolysis in biology class 10?

Plasmolysis is the process by which a plant cell loses water when placed in a hypertonic solution (a solution having a higher amount of solutes than the cell). The actual process behind this is the movement of water outwards due to osmosis, resulting in the shrinkage of the entire cell.

What is plasmolysis and Nucleoid?

When cell is placed in a hypertonic solution water moves out, first from cytoplasm and then from vacuole. Cell membrane shrinks away from the cell wall. This is known as plasmolysis. Nucleoid is irregularly shaped region in the prokaryotes that contain nuclear material.

What is plasmolysis short answer Class 9?

When a living plant cell loses water through osmosis, there is a shrinkage or contraction of the protoplasm away from the cell wall. This phenomena is called plasmolysis. Hope it helps you! douwdek0 and 13 more users found this answer helpful.

What is cell wall Class 9?

Hint: A cell wall is a structural layer that surrounds some types of cells just outside the cell membrane. It can be tough, flexible, and even rigid at times. It provides structural support and protection to the cell while also acting as a filtering mechanism.

What is plasmolysis and endocytosis with example?

Endocytosis is the process of uptake of materials from outside the cell by the invagination of the plasma membrane. and plasmolysis is a process w hen a living plant cell loses water through osmosis, the contents of the cell shrink away from the cell wall. grendeldekt and 142 more users found this answer helpful.

What Happens During Transcription In Biology?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
