Study Notes

Classification Overview

Organisms encompass all living and extinct entities exhibiting characteristics of life.
Classification organizes organisms into groups based on shared traits.

Classification Tools

Dichotomous Key: A system helping scientists classify and identify organisms through a series of choices.
Scientific Name: Composed of two Latin words (Genus and species), with the genus capitalized.

Taxonomic Hierarchy

Taxonomy: The scientific study of classifying organisms, both living and extinct.
Kingdom: The highest classification level, with five main kingdoms: Plant, Animal, Fungi, Moneran, and Protist.
Phylum: Classification tier immediately below the kingdom.
Class: Groups organisms under phyla.
Order: Smaller group within the class.
Family: Further divides organisms within an order.
Genus: More specific grouping below family.
Species: The smallest and most specific classification, representing individual organisms (e.g., Monarch as a butterfly species).

Mnemonics for Classification

Mnemonic Device: "King Phillip Came Over From Germany Saturday" aids in remembering classification levels: Kingdom, Phylum, Class, Order, Family, Genus, Species.

Importance and Origin of Classification

Reasons to classifying include streamlined identification, study efficiency, and understanding interrelations among organisms.
Created by Carolus Linnaeus, a Swedish botanist known for establishing the seven levels of classification.

Naming System

Binomial Nomenclature: The formal two-name system used for naming organisms, consisting of the genus and species.

Cellular Organization

Unicellular: Organisms made of a single cell.
Multicellular: Organisms composed of many cells.
Prokaryotes: Cells lacking a nucleus, found in Moneran.

Life Forms and Examples

Moneran: The most abundant life form on Earth, including Eubacteria and Archaebacteria.
Examples from the Animal Kingdom: Humans, earthworms, cats.
Examples from the Plant Kingdom: Trees, grasses, fruits, flowers.
Examples from the Fungi Kingdom: Mushrooms, mold, yeast.
Examples from the Protist Kingdom: Plankton, amoeba, paramecium, algae, Euglena.

Cellular Structures of Different Organisms

Animals: Primarily multicellular.
Plants: Multicellular organisms.
Fungi: Can be unicellular or multicellular.
Protists: Unicellular and contain a nucleus.
Moneran (Archaebacteria and Eubacteria): Unicellular and lack a nucleus.

Nutritional Methods Across Kingdoms

Animals: Obtain food by consuming other organisms.
Plants: Use photosynthesis, deriving food from sunlight, water, and CO2.
Fungi: Absorb nutrients from other organisms; do not perform photosynthesis.
Protists: Varies; some consume food, others photosynthesize.
Archaebacteria: Typically obtain nutrients from other organisms.
Eubacteria: Decompose dead matter and obtain nutrients from other organisms.
