Transcript
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
