Study Notes
Taxonomy
- Definition: Grouping of organisms based on their characteristics, facilitating classification and study.
Classification Factors
- Structural similarities in organisms are evaluated.
- Biochemistry or biochemical pathways understanding helps differentiate species.
- Geographic distribution influences organism classification based on habitats.
- Chromosome comparison allows for genomic assessments and evolutionary relationships.
- Breeding behavior examines reproductive traits for classification.
Six Kingdoms of Life
- Eubacteria: Prokaryotic, unicellular organisms with peptidoglycan cell walls.
- Archaebacteria: Prokaryotic, unicellular organisms with unique cell wall structures not made of peptidoglycan.
- Protista: Eukaryotic group; mostly unicellular, some multicellular, with cellulose cell walls.
- Fungi: Eukaryotic, primarily multicellular (some unicellular), with chitin cell walls.
- Plantae: Eukaryotic, multicellular organisms with cellulose cell walls; primarily autotrophic.
- Animalia: Eukaryotic, multicellular organisms lacking cell walls; heterotrophic.
Cell Types
- Prokaryote: Simple, unicellular organisms lacking a nucleus.
- Eukaryote: Complex cells with a defined nucleus and organelles.
Oxygen Requirements
- Aerobic: Requires oxygen for cellular respiration.
- Anaerobic: Does not require oxygen; may tolerate or be harmed by it.
- Facultative: Capable of both aerobic and anaerobic processes.
Reproduction Methods
- Sexual reproduction: Involves the fusion of gametes.
- Asexual reproduction: Involves a single organism replicating itself without gamete fusion.
Taxonomy Levels
- Seven hierarchical levels: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Eubacteria Characteristics
- Cell type: Prokaryote with peptidoglycan in its cell wall.
- Structure: Unicellular and can be autotrophic or heterotrophic.
- Examples: E. coli, Streptococcus.
Archaebacteria Characteristics
- Cell type: Prokaryote with unique cell wall structures.
- Structure: Unicellular; can be autotrophic, heterotrophic, or perform chemosynthesis.
- Examples: Methanogens, extremophiles, halophiles.
Protista Characteristics
- Cell type: Eukaryote with cellulose in cell walls.
- Structure: Most are unicellular, some colonial, and others multicellular.
- Nutrition: Can be autotrophic or heterotrophic.
- Examples: Amoeba, paramecium, slime molds, giant kelp.
Fungi Characteristics
- Cell type: Eukaryote with chitin in cell walls.
- Structure: Primarily multicellular; some unicellular.
- Nutrition: Heterotrophic, acting as decomposers.
- Examples: Mushrooms, mildew, yeast.
Plantae Characteristics
- Cell type: Eukaryote with cellulose in cell walls.
- Structure: Multicellular organisms.
- Nutrition: Autotrophic through photosynthesis.
- Examples: Mosses, ferns, flowering plants.
Animalia Characteristics
- Cell type: Eukaryote; lacks a cell wall.
- Structure: Multicellular organisms.
- Nutrition: Heterotrophic, consuming other organisms for sustenance.
- Examples: Sponges, worms, insects, fish, shellfish, reptiles, mammals.
