Monerans, Viruses & Protists • Compare and contrast the parts of plants, animals and one-celled organisms • Identify similarities and differences among living organisms 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 Monerans • Unicellular without a ______________ Nucleus • Microorganisms: Organisms that can not be seen without a microscope • Structure: Capsule Cytoplasm DNA Cell Membrane • Reproduce asexually (binary fission) Mitosis Monerans • Classified into three types by shape Spherical (Round) 1. Cocci bacteria - ________________ 2. Bacilli bacteria - _____________ Rod Spiral (Spring) 3. Spirilla bacteria - ______________ Monerans • Harmful bacteria cause__________ disease and food spoilage • Destroyed by_____________ Antibiotics Monerans • Helpful Bacteria are used in Clean-up (oil spills) environmental ________________, digestion of food, and production of Substance that can destroy bacteria only antibiotics(______________________) food production and ______________ Viruses Living Cells • Tiny particles that invade___________ Reproduce on their own, • Cannot __________ need other living cells • Parasites: Lives off another organisms causing harm to the host • Causes diseases AIDS, COLDS, CHICKEN POX, FLU, and HERPES Viruses • Antibiotics do not help destroy viruses • Vaccines A weaken or killed version of the virus that causes your body to build antibodies • Structure: Protists • Unicellular with a _______________. Nucleus Pseudopods • Amoeba moves with _____________. •To obtain food two pseudopods form around the food particle to form a food vacuole •Reproduce asexually by binary fission (mitosis) 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) Protists • Euglena moves with ______________. Flagella •Autotroph – makes its own food Contains Chloroplasts for photosynthesis Eyespot detects light •Reproduce asexually by binary fission (mitosis) 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. 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
