TOPIC: MT 10,11 The Basic Unit of Life! Tues 11/20/12 MY GOAL: I will… recall the cell organelles and their functions Get 1. Pick up Cell On Organelle handout & Task ATTACH to ISN p.90 2. Take out Packet p.4 & ATTACH to ISN p.91 Review TYPES of Cells: ISN p.89 Review Organelle Function Cell Structure Review General Functions of Organelles 2 Major TYPES of Cells “Karyon” = nucleus PRO = NO PROkaryote = NO nucleus EU = TRUE EUkaryote = TRUE nucleus Cell Wall 1. What TYPE of cell is this? 2. What is the name of this type of cell? 3. Can you label this cell? 1. What TYPE of cell are these? 2. Which one is a PLANT cell? ANIMAL cell? How do you know? A Vacuole stores Water, nutrients, minerals, etc… So, why is the vacuole so much larger in a plant cell? Partly EMPTY Vacuole vs FULL Vacuole Handouts Cell Organelles Reinforcement Reinforcement 1. ATTACH to ISN p.90 2. Then… DON’T JUST SIT THERE!! Complete the sheet!! 1. 2. 3. 4. ISN p.91 Read directions Think Try CELL BOUNDARIES 1. Plasma/Cell membrane: Protection It has pores in it…so it Maintains Homeostasis! 2. Cell wall: Found in BOTH plant & animal cells Protects & supports Thicker/Inflex. NOT found in animal cells DIRECTION & ASSEMBLY 1. Nucleus: Control center Contains DNA (genetic mat. that det. traits) 2. Ribosomes Nuclear membrane surrounds nucleus…porous Make proteins In cyto. & attached to ER 1. Chloroplasts Contains green chlorophyll for PHOTOSYNTHESIS! Most common pigment containing plastid – there are others.. Which gives leaves colors NOTICE SURFACE AREA IN EACH 2. Mitochondria “Powerhouses”; Break down food molecules to release energy Found in BOTH plants & animals Which has more mitochondria… muscle or fat??? PACKAGING & TRANSPORT 1. Vacuole 2. Golgi Body Storage area Water, waste Packages sub. for transport to other cells or other part of cell Notice Surface Area 3. Endoplasmic Reticulum: Transports channels Also help make lipids & proteins Lastly… DIFFERENCES IN CELLS… start at 1:56 http://www.youtube.com/watch?v=o1GQy ciJaTA&feature=related HOMEWORK 1. Study this stuff over break! 2. Do something nice for someone… or two… or three Be the change you wish to see in the world
