Quiz 1: Question #3/3 (True or False)Cells Membranes are an outer barrier, which control what moves into and out of a cell. A) True B) False

Quiz 1: Question #3/3 Continue Learning (True or False)Cells Membranes are an outer barrier, which control what moves into and out of a cell. Great Job! Let’s move on to Diffusion! • True • False

Quiz 1: Question #3/3 SomeReview (True or False)Cells Membranes are an outer barrier, which control what moves into and out of a cell. Sorry, that’s not correct… Let’s Review Again! • True • False

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

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

Re-TakeQuiz But sometimes changes on the OUTSIDE force the INSIDE to take control! Your body wants to keep the inside and outside balanced… Outside Inside

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

Continue Learning Control Center Workers Security Gate & Traffic Control

REVIEW:Cell Membranes Continue Learning • 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!

DIFFUSION: Introduction (0/5) Continue Learning Watch the animation below. 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?

DIFFUSION: Equilibrium (1/5) Continue Learning Re-TakeQuiz • Particles (Molecules and Atoms) need to be balanced out… 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

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

DIFFUSION: Animation (3/5) Continue Learning Re-Take Quiz Watch this animation again! Remember to Think About: • What do you think the dots represent? • How many dots start in the corner, compared to the rest of the box? • How do the dots move? Which direction? • What is the end result? 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)! The dots are particles (molecules or atoms). There are way more dots/particles in the one corner, than the rest of the box!

DIFFUSION: Example (4/5) Continue Learning Re-TakeQuiz 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!

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