Sorry, no etymologies found.
-- A protective differentiation of the outer layer of the cell protoplasm; difficult to demonstrate, but treatment with iodine or salt solution sometimes causes shrinkage of the cell contents -- "plasmolysis" -- and so renders the cell wall apparent (_e.
Bacteria that comes into contact with honey undergo plasmolysis - they lose their moisture content to the surrounding honey and die.
Sap vacuoles must be distinguished from spores, on the one hand, and the vacuolated appearance due to plasmolysis, on the other.
These cilia appear to be attached to the cell-wall, being unaffected by plasmolysis, but Fischer states that they really are derived from the central protoplasm and pass through minute pores in the wall.
Examine microscopically and note the strongest solution which does not cause plasmolysis and the weakest solution which does plasmolyse the organism.
The bottom large panel is a magnification of the overlay panel after plasmolysis.
PI-stained GFP-ICR1 expressing leaf epidermis pavement cells before and after plasmolysis.
Plasma membrane localization of GFP-ICR1 detected following plasmolysis.
The fluorescent green patches detected after plasmolysis indicate that some of the GFP-ICR1 was not attached to the plasma membrane.
(concentration insufficient to cause plasmolysis).
