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
CapsuleCytoplasm
DNA Cell Membrane
Monerans• Classified into three types by shape
1. Cocci bacteria - ________________2. Bacilli bacteria - _____________3. Spirilla bacteria - ______________
Spherical (Round)
RodSpiral (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 _____________.
NucleusPseudopods
•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 foodContains Chloroplasts for photosynthesisEyespot 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
