A cell with chloroplasts and a cell wall made of cellulose would likely belong to a(n)
frog from Kingdom Animalia.
mushroom from Kingdom Fungi.
oak tree from Kingdom Plantae.
paramecium from Kingdom Protista.
According to the theory of _____________, mitochondria in cells today are the descendants of aerobic prokaryotes that used oxygen to generate energy.
endosymbiosis
ingestion
mutualism
parasitism
Which group of organisms is most closely related to Archeabacteria?
Animalia
Fungi
Plantae
Eubacteria
Scientists divided the kingdom Monera into two groups, the Archeabacteria and the Eubacteria. Advances in biochemistry and genetics helped to separate organisms into the two prokaryotic kingdoms.
Compare and contrast the two prokaryotic kingdoms. What is one major difference that is apparent?
Archeabacteria are the only organisms on Earth that do not contain DNA.
The chemical composition of the cell walls of each in the two kingdoms varies.
Archeabacteria are much smaller than any known organisms on Earth or in the history of Earth.
Archeabacteria are capable of producing their own food without chloroplasts, using mitochondria instead.
All fungi are
eukaryotes and autotrophic.
prokaryotes and autotrophic.
eukaryotes and heterotrophic.
prokaryotes and heterotrophic.
The characteristics describe organisms found in the domain
·organelles
·DNA in nucleus
·contains four kingdoms
·autotrophs and heterotrophs
Archaea
Bacteria
Eukarya
Monera
Which kingdom is completely composed of unicellular organisms that are prokaryotic?
Eubacteria
Fungi
Plant
Protist
Sally's teacher asked her to classify a microscopic organism found in pond water. The FIRST characteristic Sally used to figure what kingdom the organism belonged to was
cell type.
cell diameter.
number of ribosomes present.
chemical composition of cell wall.
In the new six kingdom system of classification, the six kingdoms may be grouped into three domains. The four kingdoms that are grouped in the domain Eukarya all contain organisms
are consumers.
are multicellular.
that have cell walls made of cellulose.
composed of one or more eukaryotic cells.
What domain name should replace the question mark in this chart?
Archaea
Bacteria
Eukarya
Monera
·prokaryotic cells
·contains unique rRNA
·live in extreme environments
·cell walls contain no peptidoglycan
·membranes composed of branched hydrocarbon chains
The characteristics listed above describe the domain
Archaea
Bacteria
Eukarya
Monera
·prokaryotic cells
·cell walls contain peptidoglycan
·sensitive to traditional antibacterial antibiotic
The characteristics listed above describe the domain
Archaea
Bacteria
Eukarya
Monera
Study the cladogram. Which two organisms would be the least related?
hamster and salmon
hamster and salmon
chimpanzee and salmon
chimpanzee and hamster
A student is proposing a model to compare prokaryotic cells and eukaryotic cells. The student is using string to model the cell membrane, beans to represent the ribosomes, and pipe cleaners to model the chromosomes. How will the student need to revise the model to demonstrate a prokaryotic cell rather than a eukaryotic cell?
The student will need to use beans in both models, but will use no pipe cleaners in the prokaryotic model. The same amount of string will be used in both models.
The student will use more beans in the prokaryotic model, but the same amount of string in both. The student will need to use fewer pipe cleaners in the prokaryotic model.
The student will need to use no beans in the prokaryotic cell model. The student will need circular pipe cleaners in both models. The student will use more string in the prokaryotic model to make the cell bigger.
The student will use less string for the membrane of the prokaryotic cell because the cell is smaller. The student will need to include beans in both models. The student will need to circularlize the pipe cleaners for prokaryotic DNA.
In 1758, Carolus Linnaeus drew up rules for classifying and naming plants and animals. As science knowledge about living things has developed, it has been necessary for the two kingdom classification system proposed by Linnaeus, to be changed to incorporate this new knowledge. The invention of the microscope led to the discovery of microscopic forms of life that did not fit into the classification system of the time. Advances in technology and scientific knowledge saw a four kingdom classification system developed and then a five kingdom system. More recent discoveries and developments have resulted in a six kingdom classification system.
In the five kingdom system, the monera or bacteria were distinguished by their prokaryotic cells. Now that kingdom has been divided into two domains and two kingdoms. Cite evidence that was used to devise this latest classification system.
The Archaea are ancient bacteria, first formed via endosymbiosis; the Bacteria are modern-day life forms.
The Archaea live in extreme, atypical environments and are chemosynthesizers; the Bacteria are heterotrophs.
Bacteria have cell walls with peptidoglycan and the Archaea do not; the Archaea have chloroplasts for photosynthesis.
Bacteria have cell walls with peptidoglycan and the Archaea do not; the Archaea live in extreme, atypical environments.
Which is a characteristic of a virus, but NOT a bacterium?
capsid
causes illness
damages the cells in a body
transmitted in food and drink
__________ are found in BOTH viruses AND in living single-celled organisms, such as protozoans and bacteria.
ribosomes
a nucleus
DNA or RNA
a cell membrane
Are viruses alive? The scientific debate continues. Viruses exhibit some characteristics of life, but others are missing. The MOST obvious reason why scientists still refer to viruses as non-living is that they
do not change over time.
do not contain any genetic material.
are much smaller than anything alive.
are not composed of one or more cells.
The Venn diagram represents two eukaryote kingdoms. Based on the characteristics shown, A represents __________ and B represents __________.
plants; fungi
fungi; animals
fungi; bacteria
plants; animals
What statement COULD we make about the four species based on the phylogenetic tree?
Humans are in no way similar to the other three organisms.
The is no evidence of any connection between the four organisms.
The orangutan has nothing in common with the other three organisms.
The four have molecular similarities, but have their own unique traits.
A review of the cladogram shows a common ancestor for these four types of vertebrates. Which statement BEST explains the genetics represented by the cladogram?
There are no genetic similarities among the four distinct types.
The four types of animals no longer have any genetic similarities.
Lizards and snakes are more genetically alike than lizards and birds.
A common ancestor indicates that the four once had identical genotypes.
Study the cladogram. Which two organisms would be the least related?
hamster and salmon
lizard and salamander
chimpanzee and salmon
chimpanzee and hamster
Study the cladogram above. Which statement is true regarding the organisms on the cladogram?
These organisms do not have a common ancestor.
The salamander has lungs, but not claws or nails.
The salmon is more closely related to the hamster than the lizard.
The chimpanzee is more closely related to the salamander than the lizard.
Which answer choice below highlights sections of the cladogram of organisms that are NOT a common grouping?
A hypothetical phylogenetic tree depicting the evolutionary relationship between three species is shown. What evidence would require a research biologist to revise the phylogenetic tree?
Species C lacks a homologous structure that A and B share.
A fossil is found that has characteristics of all species.
A mutation that arose in species A and C is not present in species B.
Mating behavior between species A and B are more similar than those of species C.
