  1. Biodiversity 5th Grade

  2. Biodiversity = the variation of life • Beside the Animal Kingdom, what are the other 4 kingdoms?

  3. Kingdoms • Animal Kingdom • Plant Kingdom • Fungus Kingdom • Protist Kingdom • Bacteria Kingdom

  4. What are Bacteria? • Microscopic organisms • Uni-celled organisms (1 cell) • Their DNA is NOT inside a nucleus • Can be producers, consumers, AND decomposers

  5. Bacteria • Some can produce Endospores: a structure that protects them when environmental conditions are too harsh • This helps them to survive hundreds of years

  6. 3 kinds of Bacteria: • Cocci = sphere-shaped • Bacilli = rod-shaped • Spirilla = spiral-shaped

  7. Did you know? Bacteria is helpful AND harmful • Antibiotics = bacteria that produce chemicals that limit the growth or kill other bacteria • Pathogen = bacteria that causes disease • Ex. bacteria that grows in your mouth causes tooth decay –these bacteria grow on the surface of your teeth and use sugar as food

  8. Examples of Bacterial Infections: • Whooping cough • Tetanus • Tuberculosis • Strep Throat

  9. What are the differences between bacteria and viruses? • Antibiotic drugs kill bacteria • Antibiotic drugs are NOT effective against viruses • When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting them to produce the virus

  10. Is the common cold a bacterial infection or a virus? • virus

  11. Is chickenpox a bacterial infection or a virus? • Virus

  13. Protist: • Uni- or multi-celled organism that lives in moist or wet surroundings • HAS a nucleus • There are plant-like AND animal-like protists • Examples of protists: • algae, protozoans

  14. Plant-like Protists • Use sunlight to make their food • But do NOT have roots, stems, and leaves like other plants • Each algae cell has to make food

  15. Animal-like Protist

  16. Protist example: • Example: • Malaria

  17. Fungus • Multi-cellular • Like plants, they have cell walls, but unlike plants, fungi do NOT have specialized tissues and organs like leaves and roots • HAVE a nucleus • do NOT make their own food –no chlorophyll • Grow in warm, humid areas

  18. Fungus = Athlete’s foot

  19. Fungi = known as the “great decomposers”

  20. Baker’s Yeast = Fungus • Feeds on sugars in flour dough • Causes carbon dioxide to rise • Bread would be flat without this fungus

  21. Fungi examples: *Mushrooms *Mildew *Mold *Yeast

  22. What is the difference between mold and mildew? • Mold typically grows on food • Mildew typically grows on fabric, bathroom walls, other damp surfaces • Ex. If you leave your clothes in the washer too long and forget to put them in the drier, they may smell terrible and you have to re-wash them

  23. Mold: • Mildew:
