Intro to Zoo Test Review

a critter that can makes its own food from sunlight or another energy source. Doesn't have to eat to get energy.

Multicellular, except yeast. Absorptive heterotrophs. Cell walls made of chitin.

When creating your dichotomous key, you need to start with the most general characteristics first.

diagrams which depict the relationships between different groups of taxa called “clades”.

First taxonomist. Divided organisms into plants and animals. Subdivided them based on their habitat.

Probably the first cells to evolve. Live in harsh environments.

Cladograms are constructed by grouping organisms together based on their shared derived characteristics.

The initial ancestor common to all organisms within the cladogram.

The International Code for Binomial Nomenclature contains the rules for naming organisms,

a group of critters that do not have a backbone.

The most distantly related species in the cladogram which functions as a point of comparison and reference group.

When creating a dichotomous key, both qualitative and quantitative factors are considered.

Called the "Father of Taxonomy". Helped develop the naming system still used today. 18th century taxonomist.

A common ancestor and all of its descendants.

a group of organisms that have a backbone.

Which of these is NOT a domain.

There are about 2 million known species of organisms. This is only 5% of all organisms that have ever lived.

A botanist. First to use Latin for naming. His names were very long descriptions telling everything about the plant.

Domain, Kingdom, Class, Order, Phylum, Family, Genus, Species (correct order from broadest to specific)

a key for the identification of organisms based on a series of choices between alternative characters.

Each one corresponds to a hypothetical common ancestor that speciated to give rise to two (or more) daughter taxa

“Dichotomous” means divided into many parts.

Multicellular. Ingestive hertrotrophs. Feed on plants or animals.

When using a dichotomous key to identify specimens it is preferable to use features that do not change.

Cladograms can be constructed based on either a comparison of morphological (structural) features or molecular evidence.

Most are unicellular. Some are multicellular. Some can be autotrophs while others are heterotrophic. They are aquatic.

the arrangement of organisms into orderly groups based on their similarities.

Some may cause disease. Found in all habitats except harsh ones. Important decomposers for environment.

Multicellular. Autotrophic. Absorpb sunlight to make glucose. Cell walls made of cellulose.

All names must be approved by the International Naming Congress (International Zoological Congress)

the study of the classification of organisms.

A critter that has to eat other critters in order to get energy

The study of animal structure, function, and taxonomy.

When creating a dichotomous key, you can use statements or questions to divide your specimens into two groups.

Which of these are not the three things an organism must have to belong in the "Animal Club"?
