Study Notes
Plant Taxonomy Overview
- Phylum represents groups within a kingdom; in the plant kingdom, there are ten phyla.
- Common phyla include Bryophyta (mosses and liverworts), Pteridophyta (ferns), Ginkgophyta (Ginkgo), Coniferophyta (conifers), and Angiospermophyta (flowering plants).
Characteristics of Plants
- Plants are multicellular and have the ability to photosynthesize.
- Plant cell structure includes cellulose, giving cells their rounded shape.
- Unlike animals, plants cannot migrate.
Angiospermophyta (Flowering Plants)
- Reproduce using flowers, which attract pollinators through colorful petals and scents.
- Develop fruit that contains seeds.
- Have a well-defined upright stem with mechanical tissue for wind resistance.
- Adaptable stem, root, and leaf systems enable survival in various environments.
Taxonomic Classification
- Classes within phyla include Monocotyledons and Dicotyledons in the Angiospermophyta.
Monocotyledons
- Features strap-like leaves with parallel veins.
- Vascular bundles are scattered throughout.
- Contains one seed leaf and flower parts in threes or multiples of three.
- Characterized by a fibrous root system that is evenly thick.
Dicotyledons
- Distinguished by broad leaves with netted vein patterns.
- Vascular bundles arranged in rings.
- Contains two seed leaves and flower parts in multiples of 2, 4, or 5.
- Features a tap root system with one main root and many smaller branching roots.
Binomial Nomenclature
- Developed by Carl Linnaeus in 1753; a two-word naming system for plants and animals.
- Genus (capitalized) is the surname, whereas species (lowercase) is the given name, both in Latin and italicized or underlined (e.g., Rosa rugosa).
- Family names end in -aceae, such as Rosaceae.
Importance of the Binomial System
- Botanical names provide a universal language across different cultures.
- Common names can vary significantly between regions or might not exist at all.
- Botanical classifications assist in organizing plant relationships.
- Botanical names often reveal important information about plant traits.
Family and Genus
- Plants are categorized into families based on the structure of their reproductive organs.
- Genus comprises closely related species within the same family.
Understanding Species and Varieties
- Species consist of individuals that breed naturally to produce offspring with similar characteristics.
- Variety refers to groups within a species from the same geographical area in the wild.
- Subspecies differ from true species and often arise from isolation or natural selection.
Cultivar and Hybrid Formation
- Cultivars are groups within a species with minor differences due to cultivation or hybridization by humans, named in English with quotes (e.g., 'Fagus sylvatica' "Zlatia").
- Hybrids result from crossing two different parent species within the same genus (e.g., 'Viburnum x bodnantense').
- Graft hybrids are created by grafting two plants together, where new tissue develops from both parents, denoted with a "+" (e.g., 'Plant A + Plant B').
