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.
