Internal structure of Plants
Describing, naming, and classifying plants
Study of how and why plants are distributed where they are.
Study of interaction of plants with one another and with their environment
Study of plant form and structure.
The Science of Cell Structure
Ethnobotany (Economic Biology)
Focus on practical uses of plants and plant products
- -Seed that splits in halves
- -have ring-like patterns
- -two leaves
- -flowers in 4,5 or multiples of 4,5
- -non-parallel veination
- -Seed in one solid mass
- -one leave
- -scattered vascular bundles
- -flower parts in 3's or in multiples of 3's
- -parallel veination
- Genus = Noun
- Species = Adjective
Naturally occuring variation that can be perpetuated through sexual reproduction.
Acer saccarum v or var pumilla
Not naturally occuring and very often cannot reproduce "true" from seed, if it produce seed at all (sterile).
Propagated asexually ---> Cutting
between species within the same genus
- (sugar) Acer saccarum
- (silver)Acer sacchainum
Cross between to Genera
Annual Plant Lifecycle
- Complete lifecycle = 1 Growing season
- -Seed germanation
- -Vegatative growth
- -Reprodctive growth
- -Seed production
Biennial Life Cycle
Complete Life Cycle = 2 growing seasons
- First Season
- -Seed Germination
- -Vegatative Growth
- Second Season
- -Resume Vegatative growth
- -Reproductive growth
- -Seed production
Perennial Life Cycle
Lifecycle continues for several to many years in a suitable evironment
-Defined by persistant root systems
Lacking woody tissue
Indigionous to a specific region
Usually deliberate / Typical for ornamental purposes
Usually from a different continent
Very agressive plant without acknowledging where its from
Within a biological context, it disrupts natural areas and native ecosystems
Characteristics of Invasive plants
- 1. Produces abundant fruit/ seed
- 2. effective seed dispursal mechanism
- 3. Easily and readily established especially distrubed sites
- 4. grows rapidly
- 5. Agressive Competitors
Plants in an area of the same specie
All living things within an area
Living, non-living things in an area. Includes pH levels and precipitation. Interdependence
Anything that photosynthasizes
Feed directly on produces
Break down dead matter to reenergize
Austrian monk who experimented with genetics using peas. Dominant and recessive traits
William J. Beal
Founder of Michigan Botanical Garden. Longest experiment, ending in 2100.
British botonists, did a lot of traveling, classifying plants
England- came to New England to visit brother in Maine. Provided the most in-depth book of plant life in the history of the area
Ecologist. Wrote Silent Spring which warned about the dangers of pestisides. Launched the environmentalist movement.
Standard Field Guide. Manual of the botony of the Northern U.S.
Collected and classified Maine's flora and fungi.
