Bell Ringer 3.3 Chloroplast is to photosynthesis as ribosomes are to ______________________________ Name the two structures (other than the nucleus) with their own DNA in the cell. What does having their own DNA allow them to do? Cell Review!! Content so far! Cell Structure Cell Types Prokaryotes Eukaryotes Organelle Functions Prokaryotes ALWAYS Unicellular Bacteria ONLY No membrane bound nucleus Typically smaller Contain Ribosomes Eukaryotes Unicellular & Multicellular Membrane bound nucleus/organelles Everything EXCEPT bacteria Typically larger Animal Cells Centrioles (direction) No cell walls Multiple small vacuoles Plant Cells Chloroplast Site of photosynthesis Chlorophyll (green pigment) One large vacuole Cell Walls (cellulose) Prokaryotes or Eukaryotes? Pair the following descriptions with their proper cell: ___________________________ One large vacuole. ___________________________ Multiple small vacuoles. ___________________________ Smaller, simple structures ___________________________ Bacteria. ___________________________ Unicellular & Multicellular. ___________________________ Everything but bacteria cells. ___________________________ Contains centrioles ___________________________ Larger, complex structure. Functions of the organelles Match the following descriptions with the correct organelle: Powerhouse of the cell: ___________________________ Controls cell (brains): ___________________________ Stores enzymes & waste: __________________________ Cleans up cells: ___________________________ Photosynthesis (location): ________________________ Protein synthesis: ___________________________ Ribosome synthesis: ___________________________ Concept Questions 1. Why would more active cells need to reproduce more mitochondria? 2. What is so unique about the mitochondria? 3. What happens to protein synthesis without the nucleolus? 4. In terms of evolution, which one do you think came first? The prokaryote or the eukaryote? Why? 5. How do cells maintain homeostasis? 6. Where is the cytoplasm in the cell? Describe it. 7. What happens to the cells without flagellum or cilia? Agenda for today… • Review Slides/Questions • Finish Activities Packet (due today) • Don’t forget there are SIX activities total ( Act. 5 is foldable) • Foldable organelle name, description & sketch. (6 ORGANELLES) • Fold computer paper in ½ , put name of organelle on front, organelle description on inside and a picture of the organelle on the opposite side…COLOR • Eukaryotes & Prokaryotes Packet (due today) • Vocabulary/Unit Guide (due test day) • Cell Review Sheet (due tomorrow) H/W IT!!!
