Adding sodium chloride the osmotic pressure in the cells is modified and water is expelled; the observation of cells without water is more adequate.

What does plasmolysis explain?
Plasmolysis contraction of the protoplasm in a living cell when water is removed by exosmosis. The process in which cells lose water in a hypertonic solution.
What is bacterial plasmolysis?
Incipient PlasmolysisThe stage of plasmolysis at which the first sign of shrinkage of cell contents from cell wall becomes detectable is called incipient plasmolysis
How is allium cepa or the common onion prepared?
Onion is a common vegetable, and can be served cooked or raw. For medicinal purposes, onion is available for internal use as a capsule or tablet containing dehydrated onion or onion extract.
When will a plant cell undergo plasmolysis?
as soon as it sprouts
Whats it called when a Celll has no water?
plasmolysis-dehydrated
What would happen to an onion cell in distilled water?
When salt is added to onion cell, the cytoplasm shrink due to plasmolysis. When water is added to onion cell, the cytoplasm expands back to its initial shape due to deplasmolysis.
What happens to the volume of the cytoplasm during plasmolysis?
The volume of cytoplasm reduces during plasmolysis
What does plasmolysis explain?
Plasmolysis contraction of the protoplasm in a living cell when water is removed by exosmosis. The process in which cells lose water in a hypertonic solution.
What is concave plasmolysis?
cancave plasmolysis ar always irreversible and convex ar usually reversible.
The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called?
The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is plasmolysis
What happen to onion cell epidermis if placed in hypertonic solution?
Isotonic solution is a solution which contains the same concentration as present in cell. So no osmosis will occur. Hence there will be a neutral effect.
What does an onion cell look like after adding a salt solution NaCl?
This depends on the nature of the NaCl solution...If it is a Hyper-tonic solution (More concentrated solution than onion cells), water will move by osmosis down it's concentration gradient, from a region of less negative water potential (high Ψ) in the onion cell, to a region of more negative water potential (low Ψ) in the solution through a selectively/partially permeable membrane;so the onion cell will be plasmolysed and will look "flaccid" (vacuole gets smaller and shrinks).The vice versa happens with a Hypo-tonic (less concentrated solution than onion cell) NaCl solution;The onion cell will then look "turgid" (has a large vacuole exerting a pressure on the cytoplasm and pushing it towards the cell's cellwall to make it "tensed".
What is bacterial plasmolysis?
Incipient PlasmolysisThe stage of plasmolysis at which the first sign of shrinkage of cell contents from cell wall becomes detectable is called incipient plasmolysis
Is the shrinking of cytoplasm by osmosis?
plasmolysis
How many grams of nacl would you use to make 100ml of 0.9 percent nacl?
The answer is 0,9 g pure, dried NaCl.
What is the shrinkage of cytoplasm within a cell from diffusion is known as?
The shrinkage of cytoplasm within an animal cell is known as crenation.
How do you use onion as insecticide?
chop it then use it!
