Front 1

Insect differences from a vertebrate

Back 1

exoskeleton, small size, segmented body, open circulatory system, tracheal system, upside-down

Front 2

Differences from other Arthropoda

Back 2

1 pair of antennae, 3 pairs of legs, most have wings, 3 body regions

Front 3

Exoskeleton limits size because...

Back 3

growth occurs in discrete stages (instars)
surface area v. volume problem

Front 4

Pros of an exoskeleton

Back 4

protective layer, keeps water in, efficient at a small size, light enough for flight, tubular structure is stronger than rod shape

Front 5

Purpose of classifying?

Back 5

store, retrieve and communicate information. in some cases (hierarchical) it also has a predictive element

Front 6

Species

Back 6

means "kind"
2 aspects of definition: taxonomic unit and a theoretical concept

Front 7

Species Concepts

Back 7

Typological (real essence, apparent characteristics),
Phylogenetic (the smallest aggregation of a group with comparable characteristics) , Evolutionary (ancestor lineage)
Biological (reproductive isolation)

Front 8

taxonomy

Back 8

naming and describing of species

Front 9

systematics

Back 9

the study / interpretation of natural systems of relationships of biological groups
- can have hypotheses of homology (same descent)
- what structures to identity, what to name

Front 10

Incomplete metamorphosis

Back 10

hemiptera, ephemeroptera, orthoptera
