What is another name for lysis?

What is another name for lysis?

n. recovery, recuperation, disintegration, convalescence, dissolution.

What is the opposite of cell lysis?

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. The reverse process is plasmolysis.

How does the cell wall prevent lysis?

The peptidoglycan of the cell wall prevents osmotic lysis when water moves into the cell, but ONLY if the cell wall peptidoglycan is cross-linked. Anything which prevents the cross links from forming or which cuts the cross-links will weaken the peptidoglycan so that it no longer can prevent osmotic lysis.

What do Crenated cells look like?

Instead of the usual rounded biconcave shape, both these cells appear with a rounder form and spiny projections on the cell surface. In echinocytes, the spines are short, uniform and regularly spaced.

What causes Plasmolysis of plant cells?

Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does. This causes the protoplasm, all the material on the inside of the cell, to shrink away from the cell wall.

What does lysed mean?

verb (used with object), lysed, lys·ing. to cause dissolution or destruction of cells by lysins.

What is the difference between Plasmolysis and Crenation?

While crenation occurs in animals cells, cells that have a cell wall cannot shrink and change shape when placed in a hypertonic solution. In plasmolysis, water leaves the cytoplasm, but the cell wall does not collapse. Instead, the protoplasm shrinks, leaving gaps between the cell wall and cell membrane.

What is Plasmolysis Crenation?

Pickling cucumbers and salt-curing of meat are two practical applications of crenation. Plasmolysis is the term which describes plant cells when the cytoplasm shrinks from the cell wall in a hypertonic environment.

Why do animal cells burst in a hypotonic solution but plant cells do not?

Animal cells do not have cell walls. In hypotonic solutions, animal cells swell up and explode as they cannot become turgid because there is no cell wall to prevent the cell from bursting. When the cell is in danger of bursting, organelles called contractile vacuoles will pump water out of the cell to prevent this.

What is lysis in biology?

Listen to pronunciation. (LY-sis) 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 is lysis in medical terminology?

Lysis: Destruction. Hemolysis is the destruction of red blood cells with the release of hemoglobin; bacteriolysis is the destruction of bacteria; etc. Lysis can also refer to the subsidence of one or more symptoms of an acute disease as, for example, the lysis of fever in pneumonia.
