Basic Plant Reproduction, Structure, and Terminology

Monoecious(one house)

Vs. Dioecious

(two houses)

Flowers

Perfect(monoecious plants)

Vs. Imperfect

(monoecious and dioecious plants)

Two Types of Flowers:

• 1. Perfect (Complete): flowers containing BOTH male (stamen) and female (pistil) sexual parts.

• Automatically monoecious

• The male part is termed the Stamen which consists of the anther and filament.

• The female part is the Pistil, which consists of the stigma, style and ovary.

• 2. Imperfect (Imcomplete): Flowers containing the reproductive parts of only one sex.

• These imperfect flowers may be on the same plant (monoecious),

• or on separate plants (dioecious).

Imperfect flowers

conditions for survival)Vs.

Binomial Nomenclature

“The beginning of wisdom is to call things by their rightful names.”

Kingdom Phylum Class Order Family Genus Species

Animalia Cordata Reptilia Testudines Emydidae Emydoidea E. blandingii

The Top Ten reasons for using scientific names

Understand the meaning of the names!

Latin Pronunciation

Pronounce every letter except diphthongsEchinacea, Tradescantia, Opuntia, Ambrosia

“ch” is a “k” sound Polystichum, Heuchera, Aristolochia

If a word has two syllables, the accent always goes with the next to the last (called the penult); e.g., Àcer.

If a word has three or more syllables, the accent always goes either with the next to the last (penult) or the third from the last (called the antepenult).

Synandra hispidula, Onoclea sensibilis, Liriodendron tulipifera phyllum – rhizophyllum, Podophyllum, triphyllum

ae Pellaea, Arisaema, Chamaecristaau Daucus carotaEu Teucrium, LeucanthemumOe (phoebe), Platanthera peramoena, IpomoeaUi Equisetum

“oi” is not a diphthong!Pleopeltis polypodioides

Pronounce when ending with “e”Silene, canadense, sessile, hyemale

Latinized last names (one or two i’s) Dodecatheon frenchii, Emydoidea blandingii

Most trees have been feminized!Quercus rubra, Fagus grandifolia, Ulmus americana

Gymnosperms Vs.

Angiosperms

• 1. Gymnosperms (“Naked Seeds”): plants that don’t produce a protective fruit around the seed.

• Ex: all the conifers-pines, cedar, spruce, and cypress.

from, or tell story about the plant then:
