  1. Bacteria 100 words

  2. Bacteria • Prokaryotes • Genetic material is not in a nucleus

  3. Bacteria • Come in three basic shapes. • Sphere : cocci • Rod : bacilli • Spiral

  4. Bacteria : cocci Diplococcus http://student.ccbcmd.edu/courses/bio141/lecguide/unit1/shape/diplo.html

  5. Bacteria : cocci Streptococcus http://student.ccbcmd.edu/courses/bio141/lecguide/unit1/shape/gpstrep.html

  6. Bacteria : bacilli Streptococcus http://www.bioweb.uncc.edu/1110Lab/notes/notes1/labpics/lab1pics.htm

  7. Bacteria : Spiral http://www.uic.edu/classes/bios/bios100/labs/celllab.htm

  8. Bacteria • We are not going to get back into cell structure, however, it is at least worth looking at bacteria mobility. • Flagellum • long whip like structure • spins like a propeller • Rotary joint

  11. Bacteria • Bacteria exist in two Kingdoms. • Archaebacteria • Live in extreme environments • Acids, intestines, sewage, 110 degree water etc • Produce foul odors • Eubacteria • Live everywhere else • Many are beneficial

  12. Bacteria Reproduction • Asexual reproduction • Reproduction with only one parent • binary fission • one cell divides to form two identical cells • Sexual Reproduction • Two parents combine genetic material • Conjugation • Transfer genetic material through a thin bridge

  15. A tiny glimpse at the Virus Simple success

  16. Virus http://webs.wichita.edu/mschneegurt/biol103/lecture17/Ebola_EM.jpg

  17. Virus • Non-living • Do not use energy to grow • Do not respond to their surroundings • Sub-microscopic • Unable to grow or reproduce outside a host cell. • A host is an organism that harbors a virus or parasite.

  18. Virus • Each viral particle, or virion, consists of just two parts • Genetic material, DNA or RNA. • A protective protein coat called a capsid.

  19. Virus • Viruses multiply by entering a host cell and taking over cell function with its own genetic material. • The infected host cells then produce more protein and genetic material to assemble new virion.
