Presentation Transcript

  1. Monerans, Viruses & Protists

  2. Compare and contrast the parts of plants, animals and one-celled organisms • Identify similarities and differences among living organisms

  3. Vocabulary • Cilia – hairlike structures used for movement • Flagella – whiplike tail used for movement • Host – An organism that is harmed as a parasite lives off of it • Parasite – An organism that lives off of and harms another organism (host) • Pseudopod – “False foot” extensions of the cytoplasm and cell membrane used for movement • Unicellular – made up of only one cell

  4. Monerans • Unicellular without a ______________ • Microorganisms: • Structure: • Reproduce asexually (binary fission) Mitosis Nucleus Organisms that can not be seen without a microscope Capsule Cytoplasm DNA Cell Membrane

  5. Monerans • Classified into three types by shape • Cocci bacteria - ________________ • Bacilli bacteria - _____________ • Spirilla bacteria - ______________ Spherical (Round) Rod Spiral (Spring)

  6. Monerans disease • Harmful bacteria cause__________ and food spoilage • Destroyed by_____________ Antibiotics

  7. Monerans Clean-up (oil spills) • Helpful Bacteria are used in environmental ________________, digestion of food, and production of antibiotics(______________________) and ______________ Substance that can destroy bacteria only food production

  8. Viruses Living Cells • Tiny particles that invade___________ • Cannot __________ on their own, need other living cells • Parasites: • Causes diseases Reproduce Lives off another organisms causing harm to the host AIDS, COLDS, CHICKEN POX, FLU, and HERPES

  9. Viruses • Antibiotics do not help destroy viruses • Vaccines • Structure: A weaken or killed version of the virus that causes your body to build antibodies

  10. Protists Nucleus • Unicellular with a _______________. • Amoeba moves with _____________. Pseudopods • To obtain food two pseudopods form around the food particle to form a food vacuole • Reproduce asexually by binary fission (mitosis)

  11. Protists Cilia • Paramecium moves with __________. • To obtain food cilia move food into the oral groove which transports it into the cell • Reproduce asexually by binary fission (mitosis)

  12. Protists Flagella • Euglena moves with ______________. • Autotroph – makes its own food • Contains Chloroplasts for photosynthesis • Eyespot detects light • Reproduce asexually by binary fission (mitosis)

  13. Protists • Contractile vacuole is a type of vacuole involved in osmoregulation. It pumps excess water out of a cell and is found prominently in freshwater protists.

  14. 6th Grade Review - Forces • Gravity is the attraction between two objects • The greater the mass the greater the attraction • The closer the objects the greater the attraction • When two forces on an object are in opposite directions, the object will move in the direction of the greater force
