Student Sheet Name________________________________ Period _____ Title: Classification Charades Introduction: Once upon a time, the accepted pattern for classifying all living things was that they were either plants or animals. Animals included every living thing that moved, ate, and grew to a certain size and stopped growing. Plants included every living thing that did not move or eat and that continued to grow throughout life. It became very difficult to group living things this way, so early in the past century the two kingdoms were expanded into five kingdoms: Protists, Fungi, Plants, Animals, and Monera. Many biologists now recognize six distinct kingdoms, dividing Monera into two groups. This system is accepted for now. It might even hold up for a century or two. Systems of classification have changed at a far faster pace than you might expect. But that is science for you, when new evidence is found, things change. Directions: 1. Use the key on the next page to classify the organisms found in this table. Use the characteristics to help you. Organism Size Single cell multicellular multicellular Moves Green (can make their own food) Cell structures yes Some yes, some no yes no no yes Name Nucleus, Nucleus, no no cell wall cell wall Nucleus, cell wall, chloroplasts Very small single cell No and yes Some yes, some no Multicellular no no No nucleus or other organelles, cell wall Has cell wall and nucleus Kingdoms Classification 1. Is it green or does it have green cell parts? o Yes - go to 2 o No - go to 3 2. Could be a plant or a protist, or blue-green bacteria. o Single-celled? go to 6 o Multicellular: cell walls, internal structures. …………………….It’s a Plant 3. Could be a moneran (bacteria), protist, fungus, or animal. o Single-celled - go to 4 o Multicellular - go to 5 4. Could be a moneran or a protist. Can you see any detail inside the cell? o Yes - You should be able to see at least a nucleus and/or and a definite shape. Movement should be present, using cilia, flagella, or amoeboid motion. Cilia or flagella may be difficult to see. ………...……..it’s a Protist o No -Should be quite small. May be shaped like short dashes (rods), small dots (cocci), or curved or spiral shaped.. …………………..It’s a Moneran 5. Animalia or Fungi. Is it moving? o Yes - Movement can be by cilia, flagella, or complex, involving parts that contract. ……………………………………..…………………..It’s an Animal o No - Usually attached to some piece of decaying matter - may form a fuzzy coating on or around an object.…………...……………It’s a Fungus 6. Most likely Protista. If it consists of long, unbranched greenish filaments with no apparent structure inside, it is blue-green bacteria, a Moneran. 2. Use the envelopes your teacher has provided to play “Classification Charades”. These are the rules: a. one team reads the contents of their envelop and decides which trait to start with. They read that trait to the opposite team who guess the organisms’ kingdom. b. If the team doesn’t get the clue, a minus point is written down and another clue is read and so on until the team gets it right. Record only your team data. c. Then the team that read the clues is the team that responds to the clues. d. Trade envelopes when both teams have gone. Data Organism 1 2 3 4 5 6 7 8 9 Minus points Organism 10 11 12 13 14 15 16 17 18 Minus points
