Movement in cells Active Transport and Passive Transport, Transport is the way a cell moves things through a membrane.

Cell Membrane (Transport) Cell Membrane and Cell Wall: ALL cells have a cell membrane Cell Membrane protein channel protein pump Layer 1 Layer 2 SOME cells have cell membranes and cell walls – ex: plants, Cell Membrane Cell Wall Only in Plant Cells!

Function of the Cell Membrane: The cell membrane separates the cell from its environment (what surrounds the cell) The cell membrane is the “Gatekeeper” of the cell—it controls the flow of materials into and out of cell. Cell membrane helps cells maintain balance in the cell

Active Transport vs Passive Transport ENERGY REQUIRED You might need a push! Passive Transport- NO ENERGY REQUIRED Smooth sailing all the way Active and Passive Transport Homework Brainpop Active Transport

(move from crowded area to less crowded area) Passive Transport A process that does not require energy to move molecules through a membrane. (move from crowded area to less crowded area) Types of Passive Transport Diffusion Osmosis Diffusion and Osmosis Brainpop- Passive Transport

Diffusion is when molecules move from a more crowded to a less crowded area. These particles move from an area of high concentration ( a lot) to an area of low concentration (a little). outside of cell inside of cell **FOOD COLORING IN WATER LAB DIFFUSION COMPREHENSION_ TEXTBOOK LINK

Moving from more crowded to less crowded Diffusion How Diffusion Works Animation **FOOD COLORING IN WATER LAB Moving from more crowded to less crowded Diffusion Brainpop

Osmosis is the passive transport of water (**No energy required) Semi-permeable (not everything can go through it ) membrane is permeable to water, but not to sugar EGG-citing Osmosis Comprehension

How the Sodium Pumps work

Active Transport Energy is required to move materials through a cell membrane. A “pump” in the cell is used to help move materials. Proteins that work as pumps are called protein pumps. outside of cell inside of cell Carbon Dioxide molecules

Photosynthesis light+ to put together=photo/synthesis The Photosynthesis Song http://www.youtube.com/watch?v=C1_uez5WX1o T he process by which plants produce their own food and energy, using only the natural source of light and water. Plants take in CARBON DIOXIDE and produce OXYGEN- which animals breathe! Carbon dioxide + water +sunlight -> glucose(food ) + oxygen  www.brainpop.com/science/cellularlifeandgenetics/photosynthesis/ Photosynthesis Comprehension
