Study Notes
Levels of Classification
- Consists of seven hierarchical categories: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Progresses from broadest (Kingdom) to most specific (Species).
Kingdom
- Broadest classification group, encompassing five main categories: Animals, Plants, Fungi, Protists, and Monerans.
- Animals are the largest kingdom, composed of multi-celled, eukaryotic organisms.
- Plants constitute the second largest kingdom, also multi-celled and eukaryotic.
- Fungi includes decomposers like yeast, molds, and mushrooms.
- Protists are the smallest group, characterized as single-celled and eukaryotic.
- Monerans consist of bacteria, single-celled and prokaryotic organisms.
Scientific Nomenclature
- Scientific names follow a specific format: Genus name is capitalized, Species name is in all lower case, both italicized.
- Genus represents the 6th level of classification, while Species denotes the 7th and final level.
- Species is defined by the organisms' ability to breed and produce fertile offspring.
Classification Hierarchy
- 7 levels in order: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Each subsequent level becomes more specific in categorizing organisms.
Types of Organisms
- Organisms are classified based on:
- Ability to produce food: Autotrophs make their own food (e.g., plants, some protists).
- Cellular structure: Heterotrophs must consume food (e.g., animals, fungi, some protists).
Phyla and Types of Animals and Plants
- Animal kingdom divided into 35 phyla.
- Animals categorized as vertebrates (with backbone) or invertebrates (without backbone).
- Plants categorized as vascular (with vascular tissue for transport) or non-vascular (lacking such tissue).
Cell Structure
- Prokaryotic organisms (e.g., Monerans) lack a nucleus, distinguishing them from eukaryotic organisms (e.g., Animals, Plants, Fungi, Protists) which have a defined nucleus.
