Remember that… All living things are made of cells. Cells are always experiencing changing environments! Outside Change  Inside Change Cells need to maintain balance…. REVIEW: What are cells? Continue Learning

Homeostasis is the process of keeping the inside of cells stable and healthy… Regardless of the craziness going on around the cell! INSIDE OUTSIDE REVIEW: What is homeostasis? Continue Learning

OutsideInside But sometimes changes on the OUTSIDE force the INSIDE to take control! Your body wants to keep the inside and outside balanced… Re-Take Quiz

Cells are mini-factories… They have all of these parts inside that work together! And they have gates on the outside to secure the property! REVIEW: Cell Structure & Function Continue Learning

Control Center Workers Security Gate & Traffic Control Continue Learning

REMEMBER:REMEMBER: –Cell Membranes are the outer covering of cells. –Cell Membranes are semi-permeable… only some things can enter and leave! –Cell Membranes are a made of 2 lipid layers with channels! REVIEW: Cell Membranes Continue Learning

DIFFUSION: Introduction (0/5) Watch the animation below. Questions to Think About: Questions to Think About: 1. What do you think the dots represent? 2. How many dots start in the corner, compared to the rest of the box? 3. How do the dots move? Which direction? 4. What is the end result? Continue Learning

Particles (Molecules and Atoms) need to be balanced out… DIFFUSION: Equilibrium (1/5) This is NOT balanced! Notice all of the dye-particles are concentrated in the center and bottom of the water! This IS balanced! Notice the dye particles are now spread out throughout the water! “Balance” = Equilibrium Re-Take Quiz Continue Learning

Diffusion is the movement of particles from HIGH to LOW concentration, ultimately reaching equilibrium (without the use of ENERGY)! DIFFUSION: Definition (2/5) Particles are claustrophobic, they like to be spread out and have their own equal spaces! BALANCED Continue Learning Re-Take Quiz

Watch this animation again! Remember to Think About: 1.What do you think the dots represent? 2.How many dots start in the corner, compared to the rest of the box? 3.How do the dots move? Which direction? 4.What is the end result? DIFFUSION: Animation (3/5) The dots are particles (molecules or atoms). There are way more dots/particles in the one corner, than the rest of the box! The dots/particles move from an area with MORE (High Concentration), to an area with LESS (Lower Concentration)! The dots/particles are evenly spread out and balanced (in Equilibrium)! Continue Learning Re-Take Quiz

DIFFUSION: Example (4/5) Diffusion of Dye particles/molecules: Dye particles all start on top of water….HIGH Concentration! Dye particles need to be balanced… Dye particles move to areas with LOWER Concentration (fewer particles) Dye particles reach EQUILIBRIUM! Continue Learning Re-Take Quiz

Start: There are tons of particles outside the cell, and none on the inside! DIFFUSION: Example (4/5) Particles move across the Cell Membrane from HIGH to LOW concentration! End: The number of particles on the inside & outside of the cell is balanced! EQUILIBRIUM! Start the Quiz Re-Take Quiz
