1 CELLS AND THEIR ENVIRONMENTS
OSMOSIS CELLS AND THEIR ENVIRONMENTS

2 DIFFUSION The random movement of particles.

3 DIFFUSION IS.... Particles move from greater concentration to lesser concentration or from great % to less %

4 KEY WORDS OF DIFFUSION PASSIVE TRANSPORT CONCENTRATION GRADIENT (%HI -> %LOW) EQUILIBRIUM

5 WHAT IS OSMOSIS????

6 WHAT CONDITIONS CAUSE OSMOSIS????
HYPOTONIC------ISOTONIC------HYPERTONIC

7 HYPOTONIC: Water moves INTO the cell (like blowing up a balloon)
ISOTONIC: water moves both directions HYPERTONIC: water moves out of the cell (dehydration)

8 PASSIVE TRANSPORT Passive transport does NOT require energy by the cell osmosis & diffusion facilitated diffusion

9 Ion (gated) channels

10 ACTIVE TRANSPORT CARRIER MOLECULES: cell energy required!

11 Endocytosis = cell eating

12 Exocytosis = cell EXCRETING

Cellular Transport Figure 6-12 Both diffusion and facilitated diffusion are forms of passive transport, as neither process requires the cell to expend.

Cell Transport Osmosis and Diffusion.  Particles in constant motion  Run into each other and randomly spread out  Particles move from an area of high.

Diffusion & Osmosis. Cell exist in a constantly changing environment. Homeostasis: Biological balance, or stability that a cell maintains with its environment.

Transport. Concentration Gradient If there is a concentration gradient, movement will occur After concentrations are equal= dynamic equilibrium – Dynamic.
