Study Notes

Insect Taxonomy

Classification system that organizes organisms to reveal natural relationships.

Kingdom

Characteristics: heterotrophic, multicellular, and eukaryotic organisms.

Phylum

Invertebrates with key features: an exoskeleton, segmented bodies, and jointed legs.

Class

Distinctive traits: six legs, wings, two antennae, and three body segments (head, thorax, abdomen).

Simple Metamorphosis

Consists of three life stages: fertilized egg, nymph, and adult.

Complete Metamorphosis

Comprises four stages: fertilized egg, larval (worm-like) stage, pupal (transformative) stage, and adult.

Body Parts of Insects

Main structures include head, thorax, and abdomen.

Head

Features: simple and compound eyes, two antennae for sound response, and various mouthparts.

Thorax

Structure: divided into three segments (prothorax, mesothorax, metathorax) and hosts legs and wings.

Abdomen

Consists of ten segments, has openings for respiration allowing oxygen circulation.

Examples of Simple Metamorphosis

Organisms such as crickets, bugs, and grasshoppers.

Examples of Complete Metamorphosis

Organisms include ants, flies, butterflies, beetles, and mosquitoes.

Arthropods

Multicellular consumers that lack chlorophyll, characterized by exoskeletons, jointed legs, and segmented bodies.
Divided into five classes: Centipedes, Millipedes, Crustaceans, Insects, and Arachnids.

Characteristics of Insects

Notable features include jointed legs, segmented bodies, exoskeletons, three pairs of legs, two antennae, and the potential for wings.

Taxonomy Order Mnemonic

Utilize the phrase: "King-Kingdom, Phillip-Phylum, Came-Class, On-Order, Friday-Family, Gave-Genus, Speech-Species" to remember the classification hierarchy.

Cell Types

Eukaryote: Organisms with cells that contain a nucleus.
Prokaryote: Organisms whose cells lack a nucleus.

Multicellular vs. Unicellular

Multicellular: Composed of many cells.
Unicellular: Composed of a single cell.

Nucleus

A cell's dense region housing nucleic acids.
