Botany Test 1

Internal structure of Plants

Plant Function

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

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

• "Two-Names"
• 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

'Bloodgood'

between species within the same genus

• (sugar) Acer saccarum
• x
• (silver)Acer sacchainum

Acer x freemani 'Autumn Blaze'

Cross between to Genera

XHeucherella alba

• Complete lifecycle = 1 Growing season
• -Seed germanation
• -Vegatative growth
• -Reprodctive growth
• -Seed production
• -Death

Complete Life Cycle = 2 growing seasons

• First Season
• -Seed Germination
• -Vegatative Growth

• Second Season
• -Resume Vegatative growth
• -Reproductive growth
• -Seed production
• -Death

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

• 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

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.
