Which of the following describes why a standardized taxonomic system is important?
A classification scheme makes sense of the vast diversity of organisms all around us
When identifying organsims, it is helpful for them all to have a scientific name in the Greek Language
When studying organisms, it is much simpler to be able to classify them into one of two kingdoms
A common system allows all organisms to have a scientific name based on their class and order
The most widely accepted classification system groups organisms into six kingdoms. What is the most appropriate kingdom classification for an organism that is multicellular, photosynthetic, and eukaryotic with cell walls containing cellulose?
Archeabacteria
Fungi
Plants
Protists
Based on this classification scheme to the right, the
European otter and the leopard are in the same…
kingdom but in different orders
genus but in different species
order but in different families
family but in different genera
The domain Eukarya includes the kingdom(s)
Protista, Plantae, Fungi, Animalia
Protista, Plantae, Bacteria
Eubacteria
Archaea, Bacteria
The prokaryotes that live in extreme environments are classified in the kingdom
Archaebacteria
Eubacteria
Fungi
Protista
The gray squirrel, Eastern fox squirrel and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?
To prevent existing named organisms from having their names changed as they become extinct.
To keep the classification system from being altered as new organisms are discovered.
To allow organisms to be placed in many classification levels at the same time.
To standardize the naming and organization of organisms to avoid confusion.
Organisms are classified today using the Linnaean system, and the following table shows the taxonomic classification of two marine organisms living along the Pacific Coast. Taxonomic classification is important to marine biologists because it provides a way to –
Prove that marine evolution occurs
Discover and name every marine organism on Earth
Designate Latin as the universal language of marine biology
Identify marine organisms and find evolutionary relationships between them
A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia. Although these organisms belong to the same phylum, they are classified as different –
Families
Species
Kingdoms
Orders
Simple leaves have single leaf petiole, or stem, while compound leaves have more than one leaflet on a petiole. This unknown leaf can be identified using the dichotomous key. Which tree does the unknown leaf come from?
Ungnadia speciosa
Sophora secundiflora
Salix nigra
Quercus laceyi
The classifications of four trees are shown in the table. Which two trees are the most closely related?
Taiwan beech and Taiwan catkin yew
Taiwan catkin yew and lodgepole pine
Lodgepole pine and Japenese maple
Japanese maple and Taiwan beech
The dichotomous key can be used to identify some conifers. Based on the key, which of these best describes the leaves and cones of the longleaf pine?
Needle-like straight leaves that are mostly over 25cm long and found in clusters of three; no thorns or cones
Flattened and scale-like leaves that are mostly over 25cm long; soft and leathery cones
Needle-like straight leaves with a length of 25cm that are mostly found in clusters of five; thorny cones
Leaves with a length of 25 cm that are found in clusters of more than five; no thorns on cones
Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water. Based on the observations of the student, which organisms most likely belong to the taxonomic group for bacteria?
Organisms 1 and 2
Organisms 3 and 4
Organisms 1 and 4
Organisms 2 and 3
Which list correctly identifies characteristics that protists share with animals?
Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box.
Which table correctly lists the characteristics of the organisms in the two kingdoms?
A student wants to use the Venn diagram below to show the characteristics of two kingdoms of organisms. The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersect. Which of these is a characteristic that the student should list in the shaded part of the diagram?
Heterotropic
Mobile
Prokaryotic
Multicellular
The diagram shows taxonomic groups and a major distinguishing characteristic of all but two of them. Which characteristics will be used to complete the chart?
