Yes. Lettuce is about 96% water, potato about 79%. Please see the link.
a lettuce.
Water. It take less to digest and gives you more than Head Lettuce
If you put the lettuce in fresh water there are more salts in the leaf than in the water, so the water will move back into the cells and make them rigid again, because the cells will swell. So if your lettuce in limp, laying it in water will make it crisp again.
depends on the salt content of the potato and how concentrated the salt is. the more salt there is in the water than the potato- the more water will exit the potato which then loses mass.
Tap water
A potatoe has more water because its a vegitable and vegitables are made up of a lot of water.
Lettuce has more water to the leaf, while cabbage is firm. They are also two totally distinct plant species (Lactuca - lettuce and Brassica - cabbage)
Iceberg lettuce actually doesn't have much nutrition at all...it is mostly water. Greener lettuces, like romane lettuce, are packed with more vitamins and other important nutrients.
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
Because the density of the sweet potato is less than that of the water.
~When you put salt in potato and then put it in the water cup, there is low water concentration in potato and more concentration in the cup of water. Due to this concentration gradient water moves from the cup into the potato by osmosis.
