Presentation Transcript

  1. Bacteria • prokaryotic • do not have a true nucleus • lack most of the organelles found in eukaryotic cells

  2. Kingdom Archaebacteria • They lack a certain compound that is present in the cell wall of eubacteria. • They can be found in salty lakes, boiling springs, sewage, and the intestines of some animals. • The archaebacteria also have some genes that are similar to genes found in eukaryotic cells.

  3. Kingdom Eubacteria • disease-causing bacteria • decomposers of organic waste • Cyanobacteria

  4. flagellum a long, threadlike structure that spins like a propeller, pushing the bacterium along

  13. Conditions Needed • food • oxygen • a way to get rid of their wastes

  14. Shapes of Bacteria • coccus • bacillus • spirillum

  15. The prefix “staph” means they are growing in a clump or cluster.

  16. The prefix “strep” means they are growing in a chain.

  17. virus nucleic acid core with a protein coat

  18. The Virus • not made of cells • cannot obtain energy • does not reproduce on its own

  19. Viruses • AIDS/HIV • chicken pox • cold sores • hepatitis

  20. Viruses • influenza • measles • mumps • polio

  21. Viruses • small pox • rabies • warts • West Nile Virus

  22. Kingdom Protista • eukaryotic cells • unicellular

  23. protozoans algae Kingdom Protista

  24. Kingdom Protista • protozoans • can usually move themselves • can capture prey

  25. Kingdom Protista • algae • does not move around • produces its own food through photosynthesis

  26. Protist Movements • cilia • short, hair-like extensions from a cell membrane

  27. paramecium cilia

  28. Protist Movements • flagella • long, whip-like extensions from a cell membrane

  29. euglena flagella

  30. Protist Movements • pseudopodia • pseudopodia false foot

  31. amoeba pseudopodia

  32. Protist Nutrition • oral groove • vacuole • anal pore vacuole oral groove anal pore

  33. Protist Nutrition • invagination • an intruding • chloroplasts invagination

  34. Kingdom Protista • plankton • a variety of bacterial and protist organisms that float in the ocean

  35. Protist Reproduction • fragmentation • asexual reproduction caused by the splitting of a colonial organism

  36. Protist Reproduction • conjugation • the union of two organisms or cells for the purpose of exchanging portions of their genetic material

  37. Kingdom Fungi

  38. Fungal Structure • hyphae • fungal cells • long filaments

  39. Fungal Structure • spores • reproduction • withstand harsh conditions

  40. zygote a diploid cell formed by the union of two gametes

  41. cap stalk gills

  42. Fungal Nutrition • saprophyte • absorbs nutrients from dead material

  43. Fungal Nutrition • parasite • absorbs nutrients from living material

  44. Fungal Nutrition • symbiosis • both species benefit from living together

  45. Fungi • symbiosis • mycorrhizae • mycor = fungus • rhizae = root

  46. Benefits of Fungi to the Environment • decomposition • reducing waste • releasing nutrients into the soil

  47. Harmful Effectsof Fungi • diseases
