Test day: The Cell - Test Review FRIDAY SEPT. 27/24 To complete this worksheet, you will need to get your notes from class. Then go over work completed in class to find the answers. If you need to use google on your Chromebook, that should be a last resort. Part of learning how to study properly is learning to go through your own material that you have collected and worked on. Part 1: Cell Theory 1. Cells were not studied until Microscopes were invented. In class we learned about different scientists and what they discovered about cells over time. Please place the famous discovery made by each scientist beside the name in the table below: Scientist: 2. Zacharias Janssen 3. Robert Hooke 4. Anton van Leeuwenhoek  5. Matthias Schleiden 6. Theodore Schwann 7. Rudolph Virchow 8. What is cell theory? 1. 2. 3. Discovery: made 1st microscope looked at cork; called particles cells found microscopic organisms "animalcules " discovered cells in plants all animals made of cells all cells come from other cell  s All living things are made of cells The cell is the smallest unit of life All cells come from freexisting cells. Part2: Prokaryotic Cells 9. What is a prokaryotic cell? bacteria ・organelles not surrounded does not have  nudeus by membra nes 10. In the table below please state the function of each organelle listed: Organelle: a. Slime Capsule b. Cell Wall c. Cell membrane d. Cytoplasm e. Nucleoid f. Plasmid g. Ribosomes h. Pili i. Flagella Function: protect cell from physical or chemical attacks Surrounds Cell membrane prote cts  separates inside from Outside; semi-permeable jell y like substance Surrounding organellas irregularly shaped region Contains DNA small circular ONA molecul  e Make proteins surface organelles aid in mobility (hairlike; thread like (tail) helps swim Imove 11. Please label the following prokaryotic cells: [pili P Slime Capsule p  i l i Cell wall cell membrane nucleoid ribosom es · cytoplas m [flagel la ribosom  e nucleord plasm id O cytopl asm Flag ella Part 3: Eukaryotic Cells 12. What is a eukaryotic cell? Contains membrane bound nucleus which contains DNA 13. In the table below please state the function of each organelle listed: Organelle: a. Flagella/Flagellum Function: b. Cillia Х c. Cell Wall d. Cell membrane e. Cytoplasm f. Nucleolus g. Nucleus makes ribosomes Stores DNA Control centre h. Ribosomes i. Rough Endoplasmic Reticulum Channels for  transport (ribosomes attached) j. Smooth Endoplasmic Reticulum k. Golgi Bodies 1. Vesicles m. Vacuoles n. Lysosomes o. Chloroplasts only in  plant cells p. Mitochondria channels for transport (no ribosomes) packages proteins into veside Carries materials into /out of around the cell Store water (nutrients  (larger in plant cells) breaks down /recycles organelles waste Contain chlorophyll photosynthesis powerho use -energ y q. Centrioles Х  r. Cytoskeleton 14. What organelles are in both prokaryotic cells and eukaryotic cells? Do they perform the same functions? riboso me cell wall cell membrane Ye s. cytopl  asm flagel la 15. Please label the following eukaryotic cells: [Gol gi Cyto plasm vesicle nucleolu s  racuol e Rough endoplasmic Nucleus reticulum க Cellmem brane [Cytopl asm Inucleol us nucleus ribosom e Amyloplas t lysos ome о  Animal Cells mitochondri a Tribosom es Smooth endoplasmi c reticulum Hysoso ma Endoplasmi c Reticulum cell wall Cell membrane Vacude  Chloroplast #Aloplast Go lgi Plant Cells Understanding the Concepts: 16. Some human cells, such as muscle cells, have more mitochondria. Why would these cells need more mitochondria? mitochondria produce energy needed for muscle cells to make us move, 17. Photosynthesis creates sugar for the cell. What organelle does the sugar need to go to next and why? Mitochondria to create energy 18. Why is it important that the cell membrane is semi-permeable? Food comosin. Waste goes out. cell membrane is selective About What goes in & out  19. Why are vacuoles in plant cells many times larger than vacuoles in animal cells? Plants need water for plastosyntharis. 20. Cells can have many of the same kinds of organelles such as mitochondria, ribosomes, and vesicles. Why do you think each cell only has one nucleus? ・One set of DNA. One control centre.
