Cell Theory Match the following scientists with their contribution to the cell theory. 1. Schleiden concluded that all plants were made of living cells. 2. Robert Hooke was the first person to see and name the cell. 3.van leeuwenhoek was the first person to see living, moving cells. 4. Virchow originated the idea that every cell comes from another living cell. 5. Schwann concluded that all animals were made of living cells. 6. The three main ideas of the cell theory a. Cells are the basic units of life b. All living things are made up of cells c. cells come from other cells 7. How did the development of microscopes aid in the discovery of cells structure and function? It provided a tool to be able to see individual cells. 8. What does spontaneous generation mean? Living organisms come from nonliving matter a. Pasteur proved in his experiment that non-microscopic organisms could not spontaneously generate b. Louis Pasteur showed that cells cannot spontaneously generate. Major Cell Concepts (Prokaryotic vs Eukaryotic) 9. Name two characteristics of Eukaryotic cells. A. Complex B. has a nucleus 10. Name two characteristics of Prokaryotic cells. A. Simple B. no nucleus 12. This diagram above shows a prokaryotic cell. 13. Which of these organelles can be found in both eukaryotic and prokaryotic cells. C. Cytoplasm,ribosomes,cell membrane 14. Which type of cell is more complex, a prokaryote or eukaryote? Eukaryote because they contain a nucleus and a lot of organelles. 15. A unicellular organism conducts all life processes by itself, because it is only 1 cell big. However, cells within a multicellular organism are specialized. Define what cell specialization is: Concentrate to a special activity field and practice 16. Explain (briefly) Kock’s contribution to the germ theory of disease. Koch conclusively established that a particular germ could cause a specific disease 17. Which organelle makes lipids Endoplasmic reticulum Which organelle has Sac of fluid bounded by a membrane; which stores food and water Vacuole Which organelle is the powerhouse of the cell Mitochondria Which organelle assembles proteins Ribosomes Which organelle separates the cell from its environment; controls what enters and leaves Cell Membrane Which organelle has a garbage disposal; and contains digestive enzymes; and digests food and bacteria Lysosomes Which organelle is found only in animals cells and helps the cell to divide Centrioles Which organelle assembles new proteins that will be used outside of the cell and redistributes them Ribosomes Which organelle protects plant cells; gives rigid shape The cell wall Which organelle is a clear gel-like fluid in cells that holds the organelles together Cytoplasm Which organelle has folded membranes; moves materials; modifies sorts and ,packages Mitochondria Which organelle has long hair-like projections that is used for movement in cells Flagella Which organelle provides instructions for the cell Nucleus Which organelle manufactures ribosomes Nucleolus Which organelle transforms light energy into chemical energy in plant cells. Chloroplasts 18. Name two ways to distinguish a plant cell from an animal cell.  1. Large vacuole 2. Centrioles 19. Which of these organelles can be found in both plant cells and animal cells Mitochondria,Nucleus,Ribosomes 20. How much is a specimen being magnified if the eyepiece has a magnification of 15X and the objective being uses has a magnification of 20x 300 21. Not sure 22. What is the function of the diaphragm Controlling light amount 23. Which adjustment knob should you use on the high power Fine Focus 24. What is the magnification of the eyepiece Between 5X and 30X
