Define osmosis and characterize isotonic, hypertonic and hypotonic solutions and what happens to the cells when placed into these solutions and the direction of water movement if any. Also, state which tonicity is optimal for animal cells and why?

Step 1
Osmosis: Osmosis is the movement of water molecules across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration, until equilibrium is reached. Show more…

1. Define osmosis. 2. Characterize isotonic, hypertonic, and hypotonic solutions and explain what happens to cells osmotically in each of these environments. 3. State which tonicity is optimal for animal cells and explain why. 4. State which organs maintain optimal extracellular fluid tonicity.
Sri K.
1. Define hypertonic, isotonic, and hypotonic solutions. Compare and contrast what would happen to an animal cell and a plant cell if submerged in each of the three solutions. 2. Using your own words, define diffusion, osmosis, and concentration gradient. Please be as detailed as possible.
