In biology, lysis refers
to the breakdown of a cell caused by damage to its plasma (outer) membrane
. It can be caused by chemical or physical means (for example, strong detergents or high-energy sound waves) or by infection with a strain virus that can lyse cells.
What happens when cells lyse?
To lyse is
to break apart a larger particle into smaller pieces
. Lysis, or the process of lysing, can occur both inside and outside of the cell. While localized lysis can result in a tiny puncture of a cell wall or cell membrane, harsher chemical lyses result in the expulsion of all cellular contents and cell death.
Does Lyse mean burst?
Osmotic lysis is
the bursting of a cell
, aka a “cell explosion” or “cytolysis”, because of an overabundance of fluid. The cell’s membrane is not large enough to accommodate the excess fluid, causing the membrane to break open, or lyse.
Does lyse mean shrink?
Crenation – cell
shrinks by osmosis
because H2O leaves cell. solution is HYPERtonic (hyper – means excess, hypo – means insuffient.
What is it called when a cell explodes?
Cytolysis, or osmotic lysis
, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. … The presence of a cell wall prevents the membrane from bursting, so cytolysis only occurs in animal and protozoa cells which do not have cell walls.
What Crenated means?
1a : a crenate formation especially :
one of the rounded projections on an edge
(as of a coin) b : the quality or state of being crenate. 2 : shrinkage of red blood cells resulting in crenate margins.
What is another word for Lyse?

What causes bacteria to lyse?
Many species of bacteria are subject to lysis by the enzyme lysozyme, found in animal saliva, egg white, and other secretions. …
Penicillin and related β-lactam antibiotics
cause the death of bacteria through enzyme-mediated lysis that occurs after the drug causes the bacterium to form a defective cell wall.
What is the purpose of lysis?
The word lysis comes from the greek word for “loosen.” Cell lysis is the process of rupturing the membrane or walls of a cell. The purpose of a cell lysis buffer is
to use a chemical mixture to disrupt the exterior environment of a cell in a way that causes it to break open and release its contents
.
What is the opposite of Lyse?
Crenation – cell shrinks by osmosis because H2O leaves cell. solution is HYPERtonic (hyper – means excess, hypo – means insuffient.
Can human cells burst?
Human
cells can burst due to the effects of osmosis
. … Water will continue to flow until equilibrium is reached (when the concentration inside the cell is equal with the concentration outside the cell) or when the cell cannot take on any more water and bursts.
Can cell wall burst?
A cell wall is found in plant cells. It surrounds the constituents of the cell and prevents it from bursting. Hence, if placed in a hypotonic solution, the plant cell may not necessarily burst,
however, it swells up
.
Can cells burst?
A single
animal
cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst. … Plant cells have a cell wall around the outside than stops them from bursting, so a plant cell will swell up in a hypotonic solution, but will not burst.
What causes Crenated cells?
Echinocytes (crenated red cells) are frequently caused by
hypertonicity or alkalinity of the staining solution
. Stomatocytes may form when the staining solution is too acidic.
What happens during crenation?
crenation The
shrinkage of cells that occurs when the surrounding solution is hypertonic to the cellular cytoplasm
. Water leaves the cells by osmosis, which causes the plasma membrane to wrinkle and the cellular contents to condense.
