Question

Can you explain the movement of salt and water molecules in and out of the tomato cells?

Answer 1

the diffusion (movement) of water is called OSMOSIS

During osmosis water moves from an area of high concentration to an area of low ocncentration

For example, if there is a drought for a certian period of time and all of a sudden a big rain storm comes, the cells of the tomato will take in the water thru osmosis bc the water goes from high conc. to low conc.

Answer 2

If you take a slice of tomato and put it in a container of pure water, the fresh water concentration would be higher in the container, than in the tomato slice.  Through the natural process of osmosis (which is a type of diffusion), the water molecules would enter into the tomato slice, trying to reach equilibrium.  In the case of salt, since there is more salt in the tomato slice than in the outside fresh water, the salt would diffuse from the tomato out to the container.

If you were to do this experiment by putting the tomato slice into a container of salt water, the exact opposite would happen.

Remember, that diffusion refers to the movement of material from a high concentration to a low concentration.  Osmosis, which is a type of diffusion, only refers to the movement of water from a high concentration to a low concentration.

Answer 3

Osmosis-moving from a high concentration to a low concentration through a semi permiable membrane.
