plasmolysis

These properties also make it useful for demonstrations of plasmolysis.

The plasmolysis damage to my lilacs and other plants will linger, as will the threat of disease.

For yeast extract, when this process is triggered by the addition of salt, it is known as plasmolysis.

Pictures of plasmolysis in Elodea and onion skin.

This, plasmolysis, causes the membrane to recede from the wall and is responsible for wilting in plant cells.

Prolonged periods of dehydration, however, can lead to permanent wilting, cell plasmolysis, and subsequent death.

He is remembered for his investigations of plasmolysis and the morphology of plant protoplasm.

Freezing injury is a result of lost permeability, plasmolysis, and post-thaw cell bursting.

This is known as plasmolysis.

It bears an ugly-sounding name, plasmolysis.

They are liable to scorch (plasmolysis), so use sparingly and keep them away from leaf and stems.

This always follows plasmolysis.

The cell takes on the appearance of a pincushion, and the plasmodesmata almost cease to function because they become constricted: a condition known as plasmolysis.

A botanist friend who dropped by told me my plants were experiencing plasmolysis: destruction of protoplasm caused by severe water loss.

It can be either concave plasmolysis or convex plasmolysis.

Convex plasmolysis is always irreversible while concave plasmolysis is usually reversible.

The water in the yeast cell escapes through the cell mebrane into the solution causing the cell to experience plasmolysis, caving in on itself and dying.

In plasmolysis, the cell wall stays intact, but the plasma membrane shrinks and the chloroplasts of the plant cell concentrate in the center of the cell.

Through observation of plasmolysis and deplasmolysis it is possible to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane.

Further water loss causes plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane.

In the case of a plant cell, the flow of water out of the cell may eventually cause the plasma membrane to pull away from the cell wall, leading to plasmolysis.

There are some mechanisms in plants to prevent excess water loss in the same way as excess water gain, but plasmolysis can be reversed if the cell is placed in a weaker solution (hypotonic solution).

As soon as I learned about plasmolysis - and that I had a bad case of it - I lost no time in buying two of these hoses, one for the back garden and one for the front.

This is the main chemical ingredient of a method of lawn weed killing that literally sucks the sap out of leaves upon which it rests by reversing (plasmolysis) the principle (osmosis) by which plants absorb nutrient solutions from the soil.
