  1. Bacterial Reproduction By: Ye Rin, Viki

  2. Vocab Definitions • Binary Fission: a process where one cell divides into two identical cells • Asexual Reproduction: a process where one parent produces identical offspring

  3. Asexual Reproduction • Type of binary fission. • Cell duplicates genetic material. • Divides into two cells. • New cells obtains: identical genetic material, ribosomes, cytoplasm

  4. It contains instructions to make new organisms. Vocab 1.Sexual reproduction: Involving two parents who transport their genetic materialsto reproduce new organisms

  5. 2.conjugation: When a bacteria transfers its genetic material to another bacteria for reproducing, it uses a thin,threadlike line to join together. They separate after the transfer

  6. Sexual reproduction? • A new combination of genetic materials. • Bacteria combine genetic materials by conjugation, • but conjugated bacteria can’t really have abilities to increase a new bacteria, • because they form different than their parents.

  7. Gram negative: • They don’t have colors. They don’t have the outer membrane. They have violet colors They have an outer membrane. • It divides whether itgram colorsor not. Gram positive: Gram stain Gram positive= violet Gram negative= no color

  8. List of Bacteria Gram Positive Gram Negative Salmonella (in intestines) Helicobacter (in stomach, liver, intestines…) Campylobacter (in stomach, intestines…) Klebsiella (pneumonia) Neisseria (Meningitis) • Propionibacterium (acne) • Staphylococci (found on skin, some are harmless) • Streptococci (can cause pneumonia) • Clostridia (some cause dangerous diseases-Tetanus, Botulism) • Enterococci (inside human intestines)

  9. Check it!  Bonus! • Have you ever wondered how fast can bacteria reproduce? • Every 20 minutes rapidly reproduce nearly five-thousand billion and billion bacteria in one day! • http://www.youtube.com/watch?v=gEwzDydciWc • 50,000,000,000,000,000,000 Believe it or not
