Study Notes
Plant Variety Protection Act
- Allows breeders to recoup research costs through exclusive marketing rights.
- Requires that plant varieties be uniform, stable, and distinct.
- Grants exclusive marketing rights for new plant cultivars within the U.S.
Exclusions of the Plant Variety Protection Act
- Does not permit patenting of asexually reproduced cultivars.
Ecosystem Roles
- Plants primarily act as producers within ecosystems.
Decomposers
- Organisms that primarily consume dead organisms or organic waste.
Weed Characteristics
- Rapid population establishment.
- High seed production rates with seed dormancy.
- Adaptations that enhance seed dispersal.
Non-Characteristics of Weeds
- Weeds do not depend on humans for propagation.
Advantages of Weeds
- Provide habitat and food sources for wildlife.
- Contribute to soil stabilization.
- Enhance the organic matter content of soil.
Non-Advantages of Weeds
- Weeds do not increase crop yields.
Benefits of Native Plants
- Require low maintenance due to adaptation to their ecosystems.
- Do not typically need additional fertilizers or pesticides.
- Offer food and habitat support for wildlife.
Invasive Plants
- Non-native species that adapt quickly to new environments without prior evolution in that area.
Monocot Characteristics
- Flower parts are organized in multiples of three.
- Have an embryo with a single cotyledon.
- Pollen structure features a single furrow or pore.
Dicot Characteristics
- Major leaf veins exhibit a reticulated pattern.
Vascular and Non-Vascular Plants
- Vascular plants include gymnosperms.
- Non-vascular plants are referred to as bryophytes.
Classification Criteria
- Plants are classified based on leaves, flowers, and seeds.
Leaf Structures
- Leaf venation refers to the arrangement of leaf veins.
- Leaf margin describes the edges of leaves.
Biennial Plants
- May complete their life cycle in one year due to variations in temperature, climatic changes, or drought conditions.
Cladistics
- Classification method based on evolutionary branching patterns.
Taxonomy in Classification
- The kingdom is the most general taxonomic category.
Kingdom Monera
- Divides into two categories: archaebacteria and eubacteria.
Plantae Characteristics
- Organisms in the plantae kingdom are multicellular and generally non-motile.
Species Definition
- Groups of plants that reliably produce individuals of the same type.
Botanical Nomenclature
- Utilizes a binomial naming system, identifying plants by genus and species, always presented in italics or underlined.
Organisms Containing Multicellularity
- Multicellular organisms are classified under the kingdoms Plantae, Fungi, and Animalia.
Organ Systems
- Comprises root and shoot systems, facilitating responses to environmental changes and processing large material volumes.
Plant Organs
- Stems, leaves, and roots are recognized as plant organs, whereas flowers are not categorized as such.
Plant Cell Types
- Parenchyma cells retain totipotency, while collenchyma cells are characterized by unevenly thickened primary cell walls.
Plant Functions
- Regulate the water cycle, serve medicinal purposes, and provide food, air, and habitat.
Weeds Description
- Weeds are plants that grow out of place, often competitive and can serve as hosts for crop diseases.
Vascular Plants
- Represent approximately 80% of all plant species.
Bryophytes
- Another designation for non-vascular plants.
