Tue
False
Classifying organisms into groups makes them easier to find and easier to communicate about.
True
False
When naming a organism with their scientific name, the family and genus is used.
True
False
Both Aristotle and Linnaeus used an artificial classification system, used a hierarchy in their system and did not originally classify microbes.
True
False
A domain is a group of similar kingdoms. This level of the classification system was not originally used by Linnaeus.
True
False
When considering the levels of the modern classification system, a phylum would contain more organisms than a class.
True
False
Which characteristics below explain why the modern classification system is better than Aristotle's system?
more organisms can be classified
some organisms can fit into more than one group
organisms can be moved to another group when needed
characteristics used to classify are vague and generalized
Which example(s) shows the correct way to write a scientific name?
genus specie
Genus Specie
Genus specie
Genus specie
When using a hierarchy in a classification system, every upper level has all the characteristics of every level below it.
True
False
Taxonomists use Latin to name organisms because:
Aristotle used it
the meanings of the words will not change
scholarly people know the language and can communicate using it
it includes a hierarchy
The Modern Classification System continues to expand because more organisms are being formed than ever before.
True
False
The Modern Classification System continues to expand because:
new environments are being explored so new organisms are being discovered
new organisms are being discovered so new groups have to be added to the classification system
technology is improving
organisms on other planets are being added
When considering the levels in the modern classification system:
a kingdom would contain more organisms than a domain
a phylum would contain more organisms than a sub phylum
the characteristics used to describe an organism in a kingdom would be more broad than those used for a class
classes are divided into orders which are divided into genus
Autotrophic organisms can be:
photosynthetic or parasitic
saprophytic are carnivorous
chemosynthetic or herbivorous
photosynthetic or chemosynthetic
When trying to determine which classification group an organism belongs on, a taxonomist will look at:
how they get their food
the chemicals in their cell wall
where they live
how they digest their food
The first characteristics a taxonomist will use to determine which kingdom an organism belong in is:
if they have a cell wall or not
if they are prokaryotic or eukaryotic
if the reproduce sexually or asexually
what chemicals are in their cell wall
One important characteristic taxonomists need to know when classifying organisms is what chemicals are present in the cell wall. Identify which statements are correct.
Fungi have cellulose in their cell wall
Plants have cellulose in their cell wall
Bacteria have cellulose in their cell wall
Algae has cellulose in their cell wall
Identify the terms that are defined correctly.
Taxonomy: science of classifying organisms into groups
Domain: largest group created by Charles Linnaeus
Binomial nomenclature: naming organisms with two names
Saprophytic: to feed from dead host
Which best describes the Modern Classification System today:
3 domains and 9 kingdoms
2 domains and 8 kingdoms
3 domains and 6 kingdoms
3 domains and 7 kingdoms
Identify the true statement or statements:
Bacteria contain peptidoglycans in their cell wall
Fungi could be classified in both Aristotle and Linnaeus's systems.
An alligator fit into more than one group in Linnaeus's system.
Fungi contain chitin in their cell wall
