What does crenation of cells mean?
krĭ-nāshən. A process resulting from osmosis in which red blood cells, in a hypertonic solution, undergo shrinkage and acquire a notched or scalloped surface.
What is crenation process?
In biology, crenation describes the formation of abnormal notched surfaces on cells as a result of water loss through osmosis. The cells start to shrivel and form abnormal spikes and notches on the cell membrane. This process is called crenation.
What do you mean by crenation and Plasmolysis?
Plasmolysis definition in biology is the contraction of the cell due to protoplast shrinking upon exposure to a hypertonic solution. In animal cells, the equivalent condition is termed crenation. Similarly, the plant and the animal cells lose water as water molecules diffuse to its concentration gradient.
What is RBC crenation?
When erythrocytes (RBCs) are put in hypertonic solution, they shrink because a hypertonic solution has a lower water potential than the cell content. In this case, exosmosis occurs which causes abnormal notching around the edge of erythrocytes. This phenomenon is called as crenation.
What is cell lysis and crenation?
Crenation – cell shrinks by osmosis because H2O leaves cell. solution is HYPERtonic (hyper – means excess, hypo – means insuffient. Crenation (opposite of Lysis -cell swells/destroyed/hypotonic)
What causes red blood cell crenation?
When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.
What’s the opposite of crenation?
Opposite of having an irregular or uneven surface, edge, or outline. even. smooth. clean. flat.
How does tonicity affect cells?
The tonicity of a solution is related to its effect on the volume of a cell. A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink. Although it is related to osmolality, tonicity also takes into consideration the ability of the solute to cross the cell membrane.
What is an example of crenation?
Food pickling is another example of crenation occurring in every day life. Vegetables such as cucumbers are placed in acidic solutions to pickle, causing water to diffuse out and the characteristic shrinkage of the crenation process.
What is crenation in chemistry?
The term comes from the Latin word crenatus which means ‘scalloped or notched’. In biology and zoology, the term refers to an organism displaying the shape (such as a leaf or shell), while in chemistry, crenation is used to describe what happens to a cell or other object when it is exposed to a hypertonic solution.
What is hemolysis and crenation?
is that hemolysis is (medicine) the destruction of red blood cells, and subsequent release of hemoglobin, at the normal end of the cell’s life while crenation is the contraction of, or formation of abnormal notchings around, the edges of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis, especially noticeable
What does crenate leaf mean?
Definition – What does Crenate mean? In botany, crenate refers to a leaf displaying scalloped margins. Plants such as Ground Ivy and Golden Ragwort have crenate leaves with rounded, jagged teeth alongside their margins. These leaves normally appear during early spring or winter before the plants reproduce.
