Study Notes

Classification System

Carl Linnaeus developed the modern classification and naming system for living organisms.
Binomial nomenclature consists of two parts: the genus (capitalized) and species (lowercase), both in Latin, either italicized or underlined.
The classification hierarchy progresses from more general categories to specific ones: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.

Six Kingdom System

All living organisms are grouped into six kingdoms, classified from simplest to most complex:
- Kingdom Archaebacteria
- Kingdom Eubacteria
- Kingdom Protista
- Kingdom Fungi
- Kingdom Plantae
- Kingdom Animalia

Kingdom Characteristics

Kingdom Eubacteria: Prokaryotic organisms found in diverse environments; includes both harmful pathogens and beneficial bacteria.
Kingdom Archaebacteria: Ancient prokaryotic organisms that thrive in extreme conditions.
Kingdom Plantae: Eukaryotic multicellular organisms with a cellulose cell wall, predominantly utilizing sexual reproduction and primarily autotrophic, performing photosynthesis.
Kingdom Animalia: Eukaryotic multicellular organisms lacking a cell wall, heterotrophic, and primarily reproduce sexually.
Kingdom Fungi: Eukaryotic, mainly multicellular organisms characterized by a chitin cell wall; includes unicellular yeast; capable of both asexual and sexual reproduction.
- Example organisms include yeast and mushrooms.
Kingdom Protista: Diverse eukaryotic organisms, including both unicellular and multicellular forms, exhibiting autotrophic and heterotrophic characteristics; recognized as a "junk drawer" kingdom because of its varied members.

Organism Types

Autotroph: Organisms that produce their own food, primarily through photosynthesis.
Heterotroph: Organisms that cannot synthesize their own food and rely on consuming other organisms.
Unicellular: Single-celled organisms.
Multicellular: Organisms composed of multiple cells.
Prokaryote: Cells without a nucleus.
Eukaryote: Cells that possess a nucleus.

Reproduction

Asexual Reproduction: Involves a single parent; offspring are genetically identical (e.g., budding, runners).
Sexual Reproduction: Involves two parents exchanging genetic material; offspring are genetically varied.

Examples of Kingdoms

Animal Kingdom: Includes various species like fish, birds, reptiles, insects, and mammals.
Plant Kingdom: Features species such as ferns, trees, flowers, and grasses.
Specific Examples:
- Dendroaspis polyepis: A highly venomous snake within Kingdom Animalia, reaching up to 14 feet.
- Phyllostachys migra: A tall bamboo species found in tropical regions, belonging to Kingdom Plantae.
- Paramecium caudatum: A unicellular protozoan with cilia for movement in Kingdom Protista.
