Homework: Complete the “practice” found on the last notebook page for today Cell – the basic unit of all life Semi-permeable – some objects can pass through cell membrane (mostly water) Basic Cell Organelles: Cell Membrane – protects cell/gatekeeper Cytoplasm – fluid inside cell/ helps keep shape Nucleus – typically holds cells genetic material Prokaryotic vs. Eukaryotic Organisms Prokaryotic – single-celled organisms, no nucleus - usually bacteria, not very complex Eukaryotic – multi-cellular organisms, nucleus - usually more complex with more organelles Movement Into and Out of Cells: Diffusion: movement from an area of high concentration to low concentration Osmosis: diffusion of water across a semi- permeable membrane Tuesday, January 15, 2013 Wednesday, January 16, 2013

2. Using Energy to Transport Materials Across the Cell Membrane Two Main Categories: Passive Transport/Diffusion (usually small particles) – Moves substances from areas of high concentration to areas of low concentration Example: Food coloring added to a beaker of water:beforeafter Active Transport (usually larger particles) – Relies on the cell using energy (ATP) to move particles across the membrane Three Categories: 1. Transport Proteins: Special proteins use energy/ATP to pump materials into cell (gatekeeper) 2. Endocytosis: membrane surrounds particles to move them inside (see diagram on next slide) 3. Exocytosis : release of substances from inside vesicles through joining and then releasing from the cell membrane (see diagram on next slide)

3. Exchanging materials between the cell and its environment Passive TransportActive Transport Diffusion Osmosis Transport Proteins use ATP Endocytosis (reverse for Exocytosis)

4. Video’s and Examples Passive and Active Transport Animations Endocytosis and Exocytosis Animation

5. Homework/Practice DIRECTIONS- First Identify if the process is moving materials by active or passive transport. Then determine if the process is diffusion, osmosis, transport proteins, endocytosis, or exocytosis. 1. WATER MOVES OUT OF PLANT LEAF, CAUSING IT TO WILT AND DRY. 2. IF YOU PLACE A TEA BAG IN WATER AND TEA IS MADE. 3. IF FOOD THAT IS TOO LARGE TO ENTER THROUGH THE CELL MEMBRANE IS BROUGHT INTO THE CELL TO KEEP IT FROM DYING. 4. YOU SMELL THE DELICIOUS ODOR OF BAKING COOKIES BEFORE YOU ENTER THE KITCHEN. 5. FRESH WATER MOVES INTO A SINGLE CELLED ORGANISM. 6. A ONE CELLED AMEOBA SURROUNDS A PARTICLE OF FOOD. 7. EXCESS SALT THAT AN IGUANA HAS SOAKED UP IN THE OCEAN IS REMOVED THROUGH THE NOSTRILS. 8. IF A PLANT PUMPS MINERALS FROM THE SOIL TO THE ROOT OF THE PLANT.

8. Page 85 Page 86 Cell Organelle Quiz and Cell Cycle Notes Warm Up: Homework: Cell cycle - normal sequence of the development and division of a cell Three main stages: 1) Interphase - cell is performing normal functions and preparing to divide - the longest part of the cycle - cell grows about twice its original size - goes about regular cell activities - DNA is copied to prepare for mitosis 2) Mitosis- nucleus splits and divides - prokaryotes do not do this (no nucleus) - usually the shortest period in cycle - goal of mitosis is to transfer DNA and other cell structures from parent cell to new cell 3) Cytokinesis – occurs directly after mitosis - parent cell pinches off - two genetically identical cells form Wednesday, January 23, 2013 Thursday, January 24, 2013 Wednesday, January 23, 2013 Thursday, January 24, 2013 Job in the Factory Cell OrganelleFunction of the Organelle Chief Executive Officer (CEO) Assembly line where workers assemble product Finishing/ Packaging department Power Source Security Guard
