Presentation Transcript

  1. The Prokaryotic Cell Designed for 10th Grade Biology Students Designed by Kari Vitale

  2. What Do We Want To Know: • History • Drawing and Labeling • Components (individually) • Defining Characteristics • Real Life Prokaryotes • Importance in Everyday Life 1 Microsoft Clip Art

  3. History • Prokaryotes Greek name • Pro “meaning” Karyote “kernel”) • Simplest structure • Life stripped down to essentials • Thought of as parent • To eukaryote • First cell formed 2 http://fig.cox.miami.edu/Faculty/Dana/105F00_4.html

  4. Drawing and Labeling • Four major components: • Cell Wall - tough protective coat • Plasma Membrane – secondary layer • Nucleoid – aka DNA • Cytoplasm – interior fluid 3 http://www.jcarroll.org/prokaryoticcell.htm

  5. Shapes: • Shape – • Spherical, • rod-like, • corkscrew 4 http://www.yuzonakanosecretmemory.com/life1.d.html

  6. Defining Characteristics • DNA, but No Nucleus • Nucleiod Region • No Organelles • Plasma Membrane • Cell Wall • Cytoplasm 5 http://www.geo.arizona.edu/Antevs/nats104/celltypes.html

  7. Real Life Prokaryotes & Prokaryotes in Everyday Life • Bacteria = Prokaryote • Many diseases • E.g. HIV, common cold, any virus 7 www.healingdaily.com/conditions/colds.htm 6 http://www.abc.net.au/science/news/stories/s393159.htm

  8. What Have We Learned: • History: Prokaryote = simple • Drawing and Labeling: • Cell wall, Plasma Membrane, Cytoplasm, Nucleoid • Shapes: Spherical, Rod-like, corkscrew • Defining Characteristics: • No nucleus, cell wall, plasma membrane, cytoplasm • Real Life Prokaryotes and Prokaryotes in Everyday Life
