Penta Jeopardy = 10x points
Name the different shapes of Bacteria
Coccus - Round
Bacillus - Rod-shaped

The Domain in which Protists can be found:
Eukarya
Define homeostasis?
Maintenance of a stable internal environment
Carl Linneus came up with this system of giving organisms a scientific name
Binomial nomenclature
Explain why viruses are not considered to be living organisms.
Viruses do not exhibit all the characteristics of life. They do not breathe/respire, obtain/use energy.
They can only replicate when in a host cell...
They are referred to as being Acellular Pathogens.
The way in which one bacterium divides to become two
Binary fission
Animal-like Protists are commonly referred to as:
Protozoa
The difference between a prokaryote and a Eukaryote is:
Prokaryotes do not have a nucleus, nor membrane-bound organellles. (Also very tiny)
Eukaryotes have a distinct(clear) nucleus and organelles with membranes that surround them. (Also much bigger)
The scientific name for a tiger is panthera tigris.
Name the Species and Genus of the tiger.
Rewrite it correctly according to Binomial nomenclature rules.
Panthera tigris.
Genus is with a Capital P for Panthera
species is with a lower case t for tigris.
Written in italics.
Underlined (compulsory if handwritten)
Penta Jeopardy = 5x points
Name a type of virus that only infects Bacteria
Bacteriophage
During unfavorable conditions a bacterium will produce a hard coating called _______________ that surrounds its nucleoid
Endospore
How are protists classified?
Name these classifications of Protists.
By the way in which Protists obtain and use energy.
Plant-like.
Animal-like.
Fungus-like.
Quad Jeopardy = 4x points
State the organelles which perform the following functions in a cell:
Stores hereditary information.
Makes proteins.
Performs Cellular Respiration.
Nucleus
Ribosomes
Mitochondrion
When humans breed specific organisms of a species to select desired traits in the offspring.
Artificial selection.
True or False:
Antibiotics are effective in killing viruses.
Say why/why not.
False.
Antibiotics can only be used on living things, such as bacteria.
Viruses can only be treated/prevented by using Antivirals (interrupts the viral life cycle) and vaccines (a weakened form of the virus which allows us to recognize it and fight it.)
The type of Bacteria that live in extremely SALTY conditions that no other organisms can survive in.
Archaebacteria
Extremophiles
Halophiles
Triple jeopardy = 3x points
The Amoeba extends its cell membrane and cytoplasm to produce specialised structures to hunt,move and eat. These structures are called:
Pseudopodia
All the Chemical reactions that occur in a cell are called:
Metabolism
A species of fish has lived in a lake in a cave for many generations, and now their eyes no longer function. Their eyes are an example of ______________.
Vestigial structures
What happens in the Lytic cycle?
The host cell makes many copies of the virus inside of it and then bursts, releasing them all at once.
the sharing of genetic material between bacteria using their Pili
Conjugation
Double Jeopardy = 2x points
These protists can have flagella, cilia and pseudopodia for movement and are both heterotrophic and Autotrophic.
Euglena.
Mr Robben's super protist :)
State the three points of cell theory.
the cell is the basic unit of life.
All organisms are made up of one or more cells.
All cells come from pre-existing cells.
A species of hummingbird depends on nectar it gets from flowers. The hummingbirds with the longest tongues are able to reach the nectar the easiest, so the population of hummingbirds evolves to have longer tongues. This is an example of __________.
Natural selection
