Question

Slugs are mostly made of water, and CELLS. Every living thing is made of TONS and TONS of cells. Cells of a slug hold its water. A slug isn't happy if it doesn't have LOTS of water in its cells. If you sprinkle salt on a slug they will shrink and die :(
WHY?? Please include: OSMOSIS, HYPERTONIC, SALT, WATER, AQUAPORIN and CELL MEMBRANES in your response.

Answer 1

Answer:

A slug would shrink and die if you were to sprinkle salt on in because it would cause water to leave the cells of the slug through the aquaporins in the cell membrane. This is because through osmosis water balances itself with the solute to reach equillibrium. When you pour salt on the slug you are making the outside a hypertonic solution that is going to draw out the water in the slug's cells.
