Cells Part 1 Click here to begin. Nerve cell grown in culture (2). NINCDS. 2005. unitedstreaming. 6 February 2006 <http://www.unitedstreaming.com/> mitochondria ribosome nucleus chloroplast Golgi bodies vacuoles Which organelle is the control center of the cell? Yeah! You’re on a roll! Cell with nucleus highlighted. Paul Fuqua. 2005. unitedstreaming. 6 February 2006 <http://www.unitedstreaming.com/> Go to next question. That is Incorrect! mitochondria ribosome nucleus chloroplast Golgi bodies vacuoles Which organelle produces most of the energy needed by a cell? So cool!! YOU ARE DOING GREAT! Cell with mitochondrion highlighted. Paul Fuqua. 2005. unitedstreaming. 6 February 2006 <http://www.unitedstreaming.com/> Go to next question. WHOA! Think about it again! mitochondria ribosome nucleus chloroplast Golgi bodies vacuoles Which organelles produce proteins in the cell? Cell with ribosomes highlighted. Paul Fuqua. 2005. unitedstreaming. 6 February 2006 <http://www.unitedstreaming.com/> WOW! YOU ARE DOING GREAT! Go to next question. Quit MONKEY-ING around and THINK about it. Orangutan Head close- up. Discovery Communications, Inc.. 2005. unitedstreaming. 13 February 2006 <http://www.unitedstreaming.com/> mitochondria ribosome nucleus chloroplast Golgi bodies vacuoles Which organelles store food and other materials needed by the cell? WOW! YOU ARE DOING GREAT! OOPS! I wonder if you plug in your brain if it would help. Click the arrow to try again. What is the total magnification of a microscope with two lenses when one lens has a magnification of 20, and the other lens has a magnification of 10? 10 30 200 2000 CORRECT! You multiply the magnification of each lens to get the total magnification. WHOA! Think about it again! Which of the following statements is NOT part of the cell theory? Cells are the basic unit of structure and function in living things. All cells are produced from other cells. Only animals are composed of cells. All living things are composed of cells. You are a great THINKER! Skeleton, from De Humani Corporis Fabrica.. IRC. 2005. unitedstreaming. 13 February 2006 <http://www.unitedstreaming.com /> What is the function of the cell membrane? To protect and support the cell To perform different functions in each cell To control what enters and leaves the cell To form a hard outer covering for the cell HINT: A cell membrane is just like a dog gate. Now try again. Gate with portcullis in Tower of London.. IRC. 2005. unitedstreaming. 13 February 2006 <http://www.unitedstreaming.com/> Why is water important to a cell? Water is the main ingredient in DNA. All proteins require water to function. Most chemical reactions in cells require water. Water is an essential organic compound for the body. HOORAY ! It is a good thing that you get to try again! Which term refers to the movement of molecules from an area of higher concentration to an area of lower concentration? collision diffusion active transport concentration You are going to Hollywood! You will be the next Science Idol! Go Back Which term refers to the movement of water molecules through a selectively permeable membrane? osmosis engulfing active transport passive transport Yeah! Let’s play CELL–EBRITY Squares. Living Cell, The. 100% Educational Videos. 2003. unitedstreaming. 13 February 2006 <http://www.unitedstreaming.com/> OOPS! I wonder if you plug in your brain if it would help. Click the arrow to try again. Which term refers to proteins that speed up chemical reactions in living things? carbohydrate enzyme amino acid nucleic acid Enzymes and their role. Paul Fuqua. 2005. unitedstreaming. 13 February 2006 <http://www.unitedstreaming.com/> It is a good thing that you get to try again! What is the function of a cell wall? To protect and support the cell To perform different functions in each cell To prevent water from passing through it To prevent oxygen from entering the cell YOU ARE RIGHT! The cell wall is like a skeleton. It protects and supports. Skeleton of dog. Paul Fuqua. 2005. unitedstreaming. 20 February 2006 <http://www.unitedstreaming.com/> MOOVE on back and try again! Oxen in Peru. Paul Fuqua. 2005. unitedstreaming. 20 February 2006 <http://www.unitedstreaming.com/> The invention of the microscope made it possible for people to discover and learn about? plants skin animals cells WONDERFUL ! OOPS! Here is a hint. Microscopes are used to look at very small objects. Hope that helps. Gecko. Paul Fuqua. 2005. unitedstreaming. 20 February 2006 <http://www.unitedstreaming.com/> Which of these scientists was the first person to observe what are now called bacteria? Ernst Ruska Hans Janssen Robert Hooke Anton von Leeuwenhoek You are right! My name is Leeuwenhoek and I observed bacteria. Anton van Leeuwenhoek (1632- 1723).. IRC. 2005. unitedstreaming. 20 February 2006 <http://www.unitedstreaming.com/> Don’t Give Up! Try Again! Cells 21
