Diffusion is the net movement of substances from an area of _____ concentration to an area of ______ concentration. 2. A cell’s membrane is semi- permeable (also called “selectively permeable”). What does this mean? 3. If a cell is in a hypertonic solution, what is the direction of the net flow of water and why? Osmosis/Diffusion Lab 75 76 4. If a cell is in a hypotonic solution, what is the direction of the net flow of water and why? 5. If a cell is in an isotonic solution, what is the direction of the net flow of water and why?

DIFFUSION & OSMOSIS.

DIFFUSION & OSMOSIS.
Homeostasis refers to the necessity of an organism to maintain constant or stable conditions. In order to maintain homeostasis, all organisms have processes.

Osmosis Osmosis is the net movement of water molecules over a partially permeable membrane from an area of less osmotic potential to an area of more negative.
