Passive membrane transport processes include ________. A. movement of water from an area of high solute concentration to an area of low concentration B. the use of transport proteins when moving substances from areas of low to high concentration C. consumption of ATP D. movement of a substance down its concentration gradient

A hypertonic solution has a higher level of solutes so the water moves out of the cells to the surroundings

A hypotonic solution has a higher level of solutes so the water moves out of the cells to the surroundings

The salt and water solution in the potato is a hypotonic solution

Osmosis is the movement of large molecules across a membrane which require embedded proteins

The plain water in this experiment is the solvent and the salt is the solute.

Passive transport requires no energy and the molecules move with the concentration gradient or from high concentration to low concentration

Active transport required no energy and the molecules move with the concentration gradient or from high concentration to low concentration.

The water on the inside of the potato with the salt molecules is an isotonic solution the same as the solution on the outside of the potato.

Water will not move by simple diffusion (osmosis) into or out of cells it requires energy or protein transporters

The solution of salt water in the potato has a lower concentration of water molecules so the water on the outside should move into the cells

A cell is determining to maintain concentration equilibrium inside and outside of the cell. In this specific case, the cell has more solute concentration inside, rather than outside provoking the cell to swell and potentially burst. An evolutionary mechanism came in to fix this problem. What is it and how does it solve this problem?
