Review What is the function of the endoplasmic reticulum? What is the function of the ribosome? Draw a cell in a hypertonic solution and explain what would happen to it according to osmosis. A cell containing 30% sugar solution is placed in 70% sugar solution. What will happen in ACTIVE transport occurs? Objectives By the end of today, SWBAT… Be ready to ace the unit test tomorrow!!! Agenda CATALYST! EGG LAB! ORGANELLE SHOWDOWN! TRANSPORT TRASHKETBALL! REVIEW GUIDE WORK TIME! EXIT QUESTION! Egg Lab! An egg is ONE cell! Underneath the shell is a semi-permeable membrane… a cell membrane! If we put this egg into a hypertonic/hypotonic solution, osmosis will occur. ORGANELLE SHOWDOWN RULES! Two teams will line up at the board. Each player has to answer the question as quickly as possible. Bring your notecards to line to review as we play. We will keep points and the team with the most points wins! NO HELPING! Automatic 2 point deduction. SHOWDOWN! This part of the cell is selectively permeable and only allows in certain things. SHOWDOWN! This is an organelle that is found both in prokaryotic and eukaryotic cells. SHOWDOWN! This is an organelle that is found only in plant cells. SHOWDOWN! All organelles are found floating here SHOWDOWN! This organelle allows sunlight to be converted into sugar. SHOWDOWN! This organelle is a pathway for proteins to reach the Golgi apparatus. SHOWDOWN! If this organelle were destroyed, then a cell could no longer create ATP (energy) SHOWDOWN! This organelle packages and ships proteins. SHOWDOWN! In prokaryotic cells, DNA is found floating here SHOWDOWN! This organelle destroys old organelles and cleans up the cell. SHOWDOWN! This organelle is the reason that plant cells are rectangular SHOWDOWN! This organelle contains the instructions for creating proteins SHOWDOWN! Food and water is stored inside of this organelle SHOWDOWN! 2 part question!! 1) Rough ER has this on it. 2) What is the function of the organelle in number 1? SHOWDOWN! 2 PART QUESTION!!! 1) This organelle is much bigger in plants than animals 2) What is the function of the answer to #1? BONUS ROUND! Each question is worth 2 points!! Which of the following is true? A produces energy for the cell D holds the DNA only in Eukaryotes C produces energy for the cell B is a pathway for proteins to travel Which of the following is FALSE? (1) holds DNA in eukaryotic cells (3) holds food and waste and is huge in plant cells (4) is only present in animal cell This is a plant cell Transport rules- Remember these to be golden A) What is the membrane permeable to? Solute: Diffusion or Active Transport Diffusion- moving towards equilibrium Active Transport- moving away from equilibrium Water: Osmosis B) Osmosis and Tonicity Calculate percentages of water (if necessary) Hypertonic- more water inside; water out; cell shrinks Hypotonic- less water inside; water in; cell expands Isotonic- same water on both side; no net movement; cell stays the same size Transport Trash-ketball! Teams will put their boards up when the timer goes off. The team with the best answer will get to shoot. The best answer will include Any work shown neatly A clear explanation from choose. So a person that I make sure your whole group knows how to get the answer If the person can’t answer I’ll move the next best group Trashketball! A cell of 4% water solution is sitting in a solution 9% water solution. 1) Draw this solution 2) Is this hypertonic, hypotonic, isotonic? 3) Where does the water move? Trashketball! A cell with a 41% concentration of sugar sitting in a 41% sugar solution. 1) Draw this solution 2) Is this hypertonic, hypotonic, isotonic? 3) Where does the sugar move? Trashketball! A cell of 25% sugar, 75% water solution is sitting in a solution 15% sugar, 85% water solution. 1) Draw this solution 2) Is this hypertonic, hypotonic, isotonic? 3) If the membrane is permeable to water only, where will the water move? Trashketball 1) What will move- solute or solvent? 2) Which way will it move? Trashketball 1) What will move- solute or solvent? 2) Which way will it move? Trashketball- Tough one! 1) What will move- solute or solvent? 2) Which way will it move? This membrane is NOT permeable to solute Trashketball If this cell were to undergo active transport… What moves? Where? Trashketball If this cell were to undergo active transport… What moves? Where? Review Sheet Work TIME!! Review sheet!! Exit Question What are you going to do to prepare for the unit test tonight?
