Study Notes
Taxonomy and Classification
- Taxonomy is the scientific discipline focused on naming and classifying organisms based on their structure, function, and relationships.
- Organisms are categorized into distinct classifications, starting with the highest rank: domains.
Cellular Differences
- Eukaryotic cells have membrane-enclosed nuclei and organelles, distinguishing them from prokaryotic cells.
- Prokaryotic cells lack a nucleus and membrane-bound organelles, making them simpler in structure.
Organism Types
- Unicellular organisms consist of a single cell, while multicellular organisms are made up of multiple cells, often of various types.
Organism Functions and Nutrition
- The function of a part in an organism refers to its specific role or activity.
- Autotrophic organisms produce their own food through processes like photosynthesis.
- Heterotrophic organisms cannot synthesize their own food and rely on consuming other organisms.
Reproductive Methods
- Reproduction is the ability of organisms to generate more of their kind.
- Sexual reproduction involves both male and female parents, while asexual reproduction requires only one parent.
Domains of Life
- The three taxonomic domains are Archaea, Bacteria, and Eukarya:
- Domain Bacteria includes prokaryotic, single-celled organisms with diverse shapes.
- Domain Archaea consists of unicellular prokaryotic organisms that share traits with eukaryotes.
- Domain Eukarya encompasses all organisms with eukaryotic cells.
Kingdoms Under Domains
- Kingdoms are further subdivisions within domains, including:
- Kingdom Bacteria: Prokaryotic, single-celled organisms lacking a membrane-enclosed nucleus.
- Kingdom Archaea: Unicellular and prokaryotic, sharing some eukaryotic characteristics.
- Kingdom Protista: Includes single-celled and simple multicellular eukaryotes.
- Kingdom Fungi: Composed of heterotrophic eukaryotes that have chitin in their cell walls and reproduce with asexual spores.
- Kingdom Plantae: Autotrophic eukaryotes, primarily all plant species.
- Kingdom Animalia: Heterotrophic eukaryotes that encompass all animals.
