Study Notes
Taxonomy
- The science of classifying and identifying living organisms, particularly plants.
Importance of Scientific Names
- Common names for plants can vary by region, leading to confusion; scientific names provide clarity and universality.
Language of Scientific Classification
- Latin is primarily used for scientific naming to ensure consistency and avoid regional variations.
Carlos Linnaeus
- Created the binomial nomenclature system, naming plants with two Latin words representing the genus and species.
Scientific Name Structure
- The first word represents the genus, indicating a group of related species.
- The second word represents the species, which identifies the specific type within the genus.
- Additional words may follow to indicate variation or cultivar within the species.
Classification Characteristics
- Plants within the same genus share similar characteristics.
- Plants classified under the same species can consistently produce offspring of the same type.
Scientific Classification Categories
- The broadest classification category is Kingdom, which includes plant and animal kingdoms.
- In the plant kingdom, the broadest category is known as Division or Phylum.
Major Divisions of the Plant Kingdom
- Four key divisions include:
- Thallophytes: Comprising algae, fungi, and lichens.
- Bryophytes: Encompassing true mosses and liverworts.
- Pteriophytes: Including ferns, horsetails, and club mosses.
- Spermatophytes: Referring to seed-bearing or flowering plants.
Subdivisions of Spermatophytes
- Spermatophytes are divided into:
- Gymnosperms: Plants with seeds that are not enclosed in an ovary, typically found in cones.
- Angiosperms: Plants with seeds enclosed within an ovary, commonly known as flowering plants.
