2 The Selectively Permeable Membrane
Only lets certain things in and out. Diffusion Moves from higher concentration to lower Doesn’t require energy Desires equilibrium Heat and Pressure can speed this up

3 Homeostasis

4 Diffusion

5 The Selectively Permeable Membrane
Osmosis The diffusion of WATER Does not take energy Desires equilibrium Isotonic solution Hypertonic solution Hypotonic solution

6 The Selectively Permeable Membrane
Active Transport Requires energy Goes against the Gradient Uses transport proteins Engulfing

7 Active Transport

8 Photosynthesis and Respiration

DIFFUSION & OSMOSIS.

DIFFUSION & OSMOSIS.
Osmosis (diffusion of water through a selectively permeable membrane) Membrane X is permeable to water but not to protein Which side has the highest concentration.

OSMOSIS OSMOSIS: The diffusion of water through a selectively permeable membrane SELECTIVELY PERMEABLE: some substances pass like water and others do.

Ch. 5 – Homeostasis & Transport What is homeostasis? It is the biological balance of relationship between an organism’s cell and its environment. Homeostasis.

Movement of Materials Through The Cell Membrane For a cell to maintain its internal environment, (i.e., achieve homeostasis) it has to be selective in.

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