Plants called corn exist in multiple countries, including the United States, England, and Scotland. In each of these locations, however, the term “corn” actually refers to different types of plants – maize, wheat, or barley.
This information best shows ―
the fact that common names easily identify organisms
the need for giving organisms a single, scientific name
the importance of grouping organisms into categories
the necessity of using Latin when naming organisms
What is a major difference between plant and animal cells?
Plant cells are prokaryotic, and animal cells are eukaryotic.
Plant cells have cell walls, and animal cells don’t have cell walls.
Plant cells are endothermic, and animal cells are exothermic.
Plant cells are heterotrophs, and animal cells are autotrophs.
Which two taxonomic groups have members that are photosynthetic?
Bacteria and Animals
Archaea and Fungi
Fungi and Plants
Protists and Plants
At one time, many scientists considered the giant panda to be more closely related to the red panda and the raccoon due to appearance and some structural similarities. Both the giant panda and red panda have five toes and a “false” thumb on each paw that help them cling to bamboo. However, for the last 50 years, scientists include the giant panda with other bears in the family, Ursidae.
Why do taxonomists sometimes change the system of classification?
Taxonomy organizes living things into similar groups making it easier to study them
Use of common names to identify organisms can be confusing.
Classification assumes that species are distinct and unchanging.
New information regarding the structure, metabolism, and DNA of organisms is found.
Which of the following characteristics is not shared by organisms of both kingdom Plantae and kingdom Fungi?
Nonmobile
Autotrophic
Cell walls present
Eukaryotic
According to the currently recognized taxonomic system, the most general group that an organism can belong to is its —
genus
species
domain
kingdom
A frog that is native to the rainforests of Central America is a member of the genus agalychnis. This genus is part of the hylidae family, and this specific frog belongs to the species callidryas.
What is the scientific name for this frog?
Agalychnis hylidae
Hylidae agalychnis
Callidryas agalychnis
Agalychnis callidryas
In which of the following Kingdoms or Domains would an organism not have a cell wall?
Plantae
Animalia
Archaea
Fungi
Orcinus orca is the scientific name for an animal commonly called a killer whale. However, this organism is not a whale at all, but rather the world’s largest dolphin. There are two main differences between whales and dolphins. The first is that whales have two blowholes while dolphins just have one. The second is that whales have baleen that allow them to filter feed while dolphins have teeth that allow them to prey on other animals.
Having a scientific name for the killer whale ―
clarifies which taxonomic kingdom to place it in
provides information about its evolution
prevents confusion among scientists
avoids misrepresentation on a dichotomous key
Which characteristic applies to all organisms in the Kingdom Protista?
Eukaryote
Prokaryote
Unicellular
Photosynthetic
Which of the following does not describe a fungus?
Cells include cell walls
Can perform photosynthesis
Absorbs food through cell walls
Reproduces using spores
Which kingdom consists of mainly multicellular producers?
Plant
Animal
Fungi
Protist
Which statement best describes members of the plant kingdom?
Unicellular, simple, autotrophic
Unicellular/multicellular, heterotrophic
Unicellular/multicellular, autotrophic
Multicellular, autotrophic
What factors do the Kingdoms Protista, Plantae, Fungi, and Animalia have in common?
They are all eukaryotes
They are all photosynthetic organisms.
They are all multicellular organisms.
They are all prokaryotes
What are the advantages of having a universal naming system for organisms?
Latin is the language most frequently spoken, as well as the most widely accepted language in the scientific and medical fields.
The scientific name of an organism does not address its habitat, diet, and life expectancy.
In the case of pathogens, the scientific name of a virus can also be applied to the disease it causes.
.
The same organism name can be recognized in all countries, thus avoiding translation issues.
The organisms Felis catus and Felis silvestris do not belong to the same —
class
family
genus
species
Two organisms within the same genus can be organized into several related —
kingdoms
phyla
orders
species
Why is it best for scientists to use the scientific name from the standardized taxonomic system?
Communication with other scientists about fish will be reduced.
The common names can be confusing when identifying organisms.
The scientific name is less descriptive of the organism.
The scientific name differentiates seahorses from ringworms
Taxonomic classification is important to biologists because it provides a way to —
identify the feeding relationships between two organisms
ensure that Latin is the universal language of biology
examine long-term evolutionary relationships
organize and name all organisms discovered
