The word "deplasmolysis" refers to the process by which a plant cell returns to its original shape after swelling due to osmosis. The IPA phonetic transcription of the word is /diːˌplæzməˈlaɪsɪs/, with stress on the second syllable. The word is derived from the prefix "de-", which means "reverse", the root "plasmoly-", which refers to the shrinking of the protoplasm in a cell, and the suffix "-ysis", which denotes a process or state of being. It is important to spell this word correctly when studying plant physiology or biology.
Deplasmolysis is a biological term used to describe the process by which a plasmolyzed cell is restored to its original non-plasmolyzed state. Plasmolysis occurs when a cell loses water through osmosis, causing the cell membrane to shrink away from the cell wall. This phenomenon is typically caused by exposing the cell to a hypertonic solution, where the solute concentration outside the cell is higher than inside.
Deplasmolysis, on the other hand, refers to the reversal of plasmolysis. It occurs when the plasmolyzed cell is returned to a hypotonic solution, where the solute concentration is lower outside the cell compared to the cytoplasm. As a result, water moves back into the cell through osmosis, causing the cell membrane to expand and regain contact with the cell wall.
This recovery process is essential for the survival and normal functioning of plant and bacterial cells. Deplasmolysis allows the cell to regain its turgor pressure, which is necessary for maintaining cell shape, rigidity, and overall cellular activities. Furthermore, it helps restore proper functioning of organelles within the cell and facilitates the transportation of nutrients and other substances across the cell membrane.
In summary, deplasmolysis is the process of reversing plasmolysis by reintroducing water to a plasmolyzed cell, allowing it to regain its turgor pressure and normal physiological functions.
The word "deplasmolysis" has its etymology derived from two components: "de-" and "plasmolysis".
1. "De-" is a Latin prefix meaning "undoing", "removal", or "reversal".
2. "Plasmolysis" is a term derived from two Greek roots: "plasma" meaning "form" or "shape", and "lysis" meaning "loosening" or "dissolution". In biology, "plasmolysis" refers to the shrinking or contraction of the cytoplasm of a plant cell due to the loss of water.
Therefore, "deplasmolysis" can be understood as the reversal or undoing of plasmolysis, where the cytoplasm of a plant cell regains its original shape or size due to the restoration of water.
