General classification
Identify an example of an interspecific hybrid
Mule, liger, wolphin
What was the initial basis of classification in the Linnaean system?
Physical features (morphology)
Name an organism that is classified as 'sexually reproducing'
Most animals, flowering plants
What type of data is used for molecular classification
A frog eats an insect off a leaf. Classify this species interaction
Predation / predator-prey relationship
Describe the binomial naming system
Scientific name made of genus and species
Name an organism that is considered 'asexually reproducing'
Bacteria, plants
Describe what a cladogram shows
Evolutionary relationships between species
List the three types of symbiotic relationships that can be classified
Mutualism, commensalism, parasitism
Name all 5 of the Kingdoms
Animalia, plantae, fungi, monera, protista
Describe 2 differences between asexual and sexual reproduction
Variation vs identical
Fast vs slow
Describe how molecular evidence may have influenced the Linnaean classification system
Explain why a 'species' can be hard to define and an example to illustrate this
It doesn't fit all organisms e.g. bacteria, viruses
Name the three domains of life
Bacteria, archaea, eukarya
Cats begin reproducing at 6-9 months of age and are pregnant for 66 days. They can have approx 1-12 offspring at a time and the mother will feed and nurture the young for a short time. Classify the cat on the r-K scale
The cat has some r traits but is more on the K side of the scale
Define the term 'clade'
A grouping of a common ancestor and all its descendants
Name the three classification systems discussed so far in unit 3
Linnaean system, methods of reproduction (r-K), molecular sequences
Plants have some further levels of classification beyond the species level. Name these.
Subspecies and variations
Frogs reproduce sexually by external fertilisation and often lay several hundred eggs, few of which do not survive. There is some parental care during gestation and their growth is relatively quick. Classify the frog based on the r-K scale
The frog has some K characteristics but is more on the r side of the scale
State the three common assumptions of cladistics
Common ancestry, bifurcation, physical change
