Cell Web Quest Name: ___________________________________ Chapter 3-2 Cell Organelles (Parts) Period: _____ Date: ___________ Use this worksheet to research and discover more about the complex Eukaryotic cells of Plants, Animals, Fungus, and Protists. Use the following questions and directions to navigate through the pages. Record the information to the questions as you find it. Find the links for this lab on our science website (no need to type in web addresses): From the Rio Norte School website pull down the staff menu to see Mr. Fiero and click on that to get to this site: http://www.sciencescion.info/index.html 1. Click ion the link “Cellular Biology” in one of the squares in the middle of the home page. 2. Scroll down on this “Cellular Biology Unit “ web page to the box with “Web Quests and their links.” 3. Find the list of links for “Cell Web Quest.” 4. You can simply click on these links rather than type in the address which are shown below. To begin, go to the website: Cells Alive http://www.cellsalive.com/howbig.htm Scroll down to and click on: “Start the Animation.” What you are looking at is the head of a pin with some microscopic items on it. You can zoom in or out with the arrows at the bottom of the box. To the right of picture of the nail is a list of items that you can click on them to see them. First use the magnification bar to see the various sized things –it is also displayed in green within the picture. By the way this “-“ is one millimeter! 1. Which item (from the list) is largest (on top of the nail)? __________________________ What is the size of this largest item? _________ micrometers (1 millionth of a meter). 2. Click on E. coli (the bacteria that lives in your intestines!) What size is it? ________ micrometers (1 millionth of a meter). 3. Click on rhinovirus (a virus that can cause colds) What size is it?? _________ nanometers (1 billionth of a meter). 4. What would you basically say about the size of cells? _________________________________________________________________ _________________________________________________________________ Next go back to the Cellular Biology webpage of our class site to find the next link and click on The Virtual Cell and click on it http://www.ibiblio.org/virtualcell/index.htm Click on the ‘virtual cell tour.’ Please click on each organelle to get information. To go to the next page, you have to cut the organelle or dissolve it, etc. -just follow the directions on the first page, then a “next “ arrow ► (blue) will appear on the left for you to click on to move to the next paragraph (like 2 of 3). Make small drawings in the column below for each organelle. 1.Centrioles are only found in __________________ cells. Centrioles They function in cell _____________________. They have _____ groups of _____ arrangement of the protein fibers. Draw a picture of a centriole in the box. 2. Lysosomes are called ______________________ sacks. Lysosomes They are produced by the ________________ body. They consist of a single membrane surrounding powerful _______________ enzymes. Those lumpy brown structures are digestive _____________. They help protect you by __________________ the bacteria that your white blood cells engulf. _______________ act as a clean up crew for the cell. Zoom in and draw what you see. 3. Chloroplasts are the site of ______________________. Chloroplasts They consists of a __________ membrane. The stacks of disk like structures are called the ______________. The membranes connecting them are the _________________ membranes. Zoom in and draw a picture. 4. Mitochondrion is the _______________________ of the Mitochondrion cell. It is the site of _______________________. It has a ____________________ membrane. The inner membrane is where most _______________ respiration occurs. The inner membranes is __________ with a very large surface area. These ruffles are called ___________. Mitochondria have their own ________ and manufacture some of their own _______________. Draw a picture of the mitochondrion with its membrane cut. 5.Rough Endoplasmic Reticulum (ER) is a series of Endoplasmic double membranes that ________ back and forth between Reticulum the cell membrane and the _______________. These (ER) membranes fill the ____________________ but you cannot see them because they are very ___________________. The rough E.R. has __________________________ attached to it. This gives it its texture. These ribosomes manufacture __________________________ for the cell. The ribosomes are the ______________________________ which manufacture proteins. Draw the rough ER with a ribosome. 6.Smooth E.R. ____________ ribosomes. It acts as a Smooth ER __________________________ throughout the cytoplasm. It runs from the cell membrane to the nuclear ________________ and throughout the rest of the cell. It also produces ___________________ for the cell. Draw a picture of the smooth ER. 7.Cell Membrane performs a number of critical functions for Cell the ________. It regulates all that _____________ and Membrane leaves the cell; in multicellular organisms it allows _________ recognition. Draw and shade the cell membrane. 8.Nucleus is called the ______________________ of the Nucleolus cell. It is a large __________ spot in eukaryotic cells. It _________________ all cell activity. The nuclear membrane has many ____________________. The thick ropy strands are the _____________________________. The large solid spot is the _____________________. The nucleolus is a spot of __________________ chromatin. It manufactures __________________________. The chromatin is _______________ in its active form. It is a __________________________________ of DNA and histone proteins. It stores the information needed for the manufacture of ____________________. Draw a picture of the nucleus and its nucleolus. 9.Golgi Body is responsible for packaging Golgi Body _________________________ for the cell. Once the proteins are produced by the ______________ E.R., they pass into the _______________ like cisternae that are the main part of the Golgi body. These proteins are then squeezed off into the little _________________ which drift off into the cytoplasm. Draw a picture of the Golgi Body as it is squeezing off the proteins. Next go back to the Cellular Biology webpage of our class site to find the next link and click on Cell Craft: Exploring the Cell Through Gaming and click on it. http://www.carolina.com/category/teacher+resources/interactiv e+science+games+and+simulations/cellcraft.do?KickerID=int_i_ hom_cellcraftgame Click on “Play Game” below the cell animation and have fun! Simply follow the directions in the interactive animation-this mainly is done by click on the cell membrane and dragging to move the cell. It has sound! Just a few questions to answer as you play the cell game: What is energy molecule that cells use to do things (like move)? _____________ If you want to you can skip movie (about a meteor) to go to level 2. Hint: You need to make more ribosomes, so click on the nucleolus in the nucleus to make 5 of them at a time. Also if you cannot make something (like slicer enzymes ) then zoom out and stretch the cell to the next resource to eat it. Survive the viral attack!! If you want to you can skip movie (about a meteor) to go to level 3. Hint: To quickly recycle all the slicer enzymes just drag your cursor all of them and click on the recycle icon. Keep going as long as you have time for this and interest.
