Title: Classifying Ornamental Plants


1
Classifying Ornamental Plants
2
At the completion of this unit students will be
able to
  • A. Describe the system used for naming and
    classifying plants.
  • B. Identify the major groups of plants.
  • C. Describe the differences between annuals,
    biennials, and perennials.

3
Interest Approach
  • On a piece of paper list as many plants as you
    can in two minutes.
  • Monocots or Dicots?
  • Deciduous or Evergreen?
  • Annual or Perennial?
  • Fern, Angiosperm, Gymniosperm

4
Classifying Ornamental Plants
  • Why do we need this?
  • It clearly identifies plants
  • Universal System

What is a Plant?
7
A. Define Plant Classification
  • Plants are classified based on the similarities
    of their characteristics.
  • Plant taxonomists compare flowering patterns,
    stem and leaf structures, life cycles, genetic
    similarities, and many other characteristics in
    deciding which plants are the most closely
    related.
  • Taxonomists use categories to group the plants.

8
A. Define Plant Classification
  • The categories, from general to specific, are
  • A. Domain

  • E. Order
  • F. Family
  • G. Genus
  • H. Species

Carolus Linnaeus
  • Father of Botany
  • Created Binomial System

22
Writing and Pronouncing Botanical Names
  • Scientific Name
  • Botanical Name
  • Binomial Name
  • They are all the same

23
Botanical Name
  • Plant names must have at least two parts.
  • Example Tagetes patula
  • Tagetes is the genus
  • patula is specific epithet
  • When combined they form the species

24
  • For ease of understanding,
  • Genus last name (related individuals)
  • Specific epithet first name (single type)
  • Warnick chad
  • What is your Bontanical Name?

25
Variety
  • Natural occurring mutation or offspring that is
    significantly different from the parent.
  • Example white flowers instead of the pink

26
Cultivar
  • A manmade variety.
  • Hence, the name, which is short for
  • cultivated variety

27
Writing and Pronouncing Botanical Names
  • Genus is always capitalized.
  • Specific epithet begins with a lowercase.
  • Both are italicized
  • Variety name follows not italicized and may be
    lised as v. or var.
  • cv. can follows same format as variety

28
  • Common Name English Ivy
  • Scientific Name Hedra helix

29
B. Identify the major groups of plants.
  • The plant kingdom has become successful all over
    the Earth.
  • They have done so by adapting to a wide variety
    of different conditions and niches. The following
    are some of the major groups of plants.

31
Bryophytes
  • Plants which are classified in the Phylum
    Bryophyta.
  • These are non-vascular plants such as mosses and
    liverworts.
  • They tend to live in damp places and are very
    limited in size due to the lack of conducting
    tissue.
  • All higher plants are in the Phylum Tracheophyta.

34
Ferns
  • Vascular plants which reproduce by spores.
  • Ferns have no true leaves but have fronds which
    have a double purpose of food production and
    spore formation.

37
Gymnosperms
  • Plants which reproduce with seeds that lay naked
    on scales.
  • Most gymnosperms reproduce using a structure
    called a cone.
  • Any gymnosperm which reproduces by cone is
    called a conifer.
  • Examples include pines, spruces, and cedars.

38

39
Gymnosperms
  • Conifers leaves are specialized to be either
    needles or scales.
  • Most conifers are evergreen, holding their
    leaves all year round. But some are deciduous,
    dropping their leaves in the winter.

41
Angiosperms
  • Are seed plants whose seeds develop within a
    fruiting body.
  • Angiosperms all reproduce by flowers, although
    many flowers are very small and not showy.
  • So if any plant has flowers, it is in the
    Angiosperm group.
  • There are two types of Angiosperm.
  • -Monocots
  • -Dicots

D. Recognize ways to Classify plants
  • Monocots and Dicots
  • Monocots
  • 1 cotyledon in a seed
  • Leaves with parallel veins
  • Vascular bundles scattered throughout
  • Root System composed of many fibrous roots with
    many hairs
  • Flower parts in 3s
