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
