Study Notes
Micropipette Handling
- A micropipette is a precision instrument that is expensive, costing around $200 each.
- It is easily broken and requires good technique to prolong its lifespan without needing repairs.
- Proper technique is crucial to ensure long use without the need for costly repairs.
Overview of Taxonomy
- Taxonomy is the science of naming, describing, and classifying all living organisms, including plants.
- Classification relies on behavioral, genetic, and biochemical differences among organisms.
- Key processes include characterization, identification, and classification.
Taxonomic Categories
- Organisms are organized into hierarchical categories: kingdom, phylum, class, order, family, genus, and species.
Carolus Linnaeus
- Known as the Father of Taxonomy, Linnaeus created systematic methods for naming and organizing species.
- Developed a hierarchical classification framework that remains in use, arranging life into kingdoms, classes, orders, genera, and species.
Taxonomic Hierarchy
- The taxonomic hierarchy can be visualized as a pyramid with seven levels:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
The Binomial Nomenclature System
- A species is identified by its combination of specific (species) and generic (genus) names, forming a binomial name.
- Names are italicized or underlined, with the genus capitalized and the species in lowercase.
- For example, the scientific name for humans is represented as Homo sapiens or Homo sapiens.
Definition of Classification
- Classification involves grouping objects based on shared characteristics.
- In scientific contexts, biology and chemistry are categorized as branches of science, demonstrating classification.
Classification of Animals
- Animals are divided into two main groups:
-
Vertebrates (with backbone)
- Includes birds, mammals, and amphibians.
- Can be warm-blooded or cold-blooded.
-
Invertebrates (without backbone)
- Encompasses a variety of phyla including Porifera, Cnidaria, Annelida, Mollusca, and Arthropoda.
-
Vertebrates (with backbone)
Notable Invertebrate Phyla
- Porifera: Sponges, simple aquatic animals.
- Cnidaria: Jellyfish, corals, and sea anemones.
- Annelida: Segmented worms such as earthworms and leeches.
- Mollusca: Includes snails, octopuses, and clams.
- Arthropoda: Largest phylum, includes insects and crustaceans.
