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

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

Monerans Harmful bacteria cause__________ and food spoilage Destroyed by_____________ disease Antibiotics

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

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

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

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

Protists Paramecium moves with __________. Cilia 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
