Yes, the Elodea leaf will swell up if it is kept in 5 percent saline water. It causes its cells to swell, which usually causes it to die.
Elodea respires in both the light and the dark. However, the rate of repiration exceeds the rate of photosynthesis when the plants are kept in the dark.
to see how long it takes for the enzyme to dissolve the starch
Germination dry pea seeds if they are soaked into water for few 24 hours are taken out and excess water is removed & that the seeds are kept covered with a wet cloth and wait for 2 to 3 days. The peas start germinating in this way but If the seeds are kept continuously under water the seeds will fail to respire and die. I hope that i have answered your question :-)
Cells must be kept in an isotonic solution.Isotonic means there is an equal concentration of solute both inside and outside of the cell.A hypertonic solution means that there is more solute in the solution compared to within the cell. Water will move out of the cell to reach an isotonic state, causing the cell to shrink. That is BAD.A hypotonic solution means that there is less solute in the solution compared to within the cell. Water will more into the cell to reach an isotonic state, causing the cell to swell and possibly burst or 'lyse'. That is also bad.That's why cells must be kept in an isotonic solution.
One pound of salt for every one gallon of fresh water. Also, as the water evaporates, add only fresh water...and slowly! When I kept fish, I would drain half of the remaining water, then mix in the fresh water, then put the mixture back into the tank. This prevents the fish from getting a fresh water shock. The water will evaporate and leave the salt behind, so if you add more salt, it will be too much.

How to make oral saline The word 'oral' means mouth and saline means salty or impregnated with salt. Oral saline is a saline solution, especially one that is used in medical purpose to cure a patient from the shortage of salt and water which pass from the body by diarrhoea, dysentery, cholera or vomiting. Oral saline is not a preventive medicine of diarrhoea or dysentery. But it helps a patient to keep in good health as the body lacks salt and water. The saline only recovers the lack of salt and water. Tom make oral saline at first one has to take about half a liter of pure water in a clean pot. The water may be boiled before preparing it. One has to clean hands washed in soap water. Then he has to take a handful of sugar or sugarcane gur and put it in the water of the container and stir it until the sugar or gur in mixed or resolved. Next, a little salt, about half a pinch of three fingers is to be mixed with the water and stir it until it resolves. Finally, the oral saline is to be kept covering the pot for use several times. It can be kept for twelve hours. After the expired time new saline will have to be made.

So long as the water is kept up to the filtration system there is no problem with doing this.
It could get contaminated, but it should be okay. You can get saline solution for contact lenses that lasts for months, and it's just salt in water.
The cell will seek homeostasis and attempt to balance itself with its environment. Since the external environment is more saline than the interior of the cell (hypertonic), the cell will lose water in an attempt to decrease the exterior salinity .
They'll think "ew, that tasted weird". And then pass it out the other end about 24 hours later. No known health complications from dogs eating contact lenses have been recorded. The saline that contacts are kept in is just salty water with enzymes in it. Give your dog some fresh water to get rid of the thirst caused by the salt in the saline. He or she will be fine.
water is kept in a cistern
They are kept in the VACUOLE
Water is kept in a Kalpis.
