Definitions Botany is the science or study of plants
Horticulture is the science and art of cultivating flowers, fruits,
vegetables, grass, and ornamental plants in an orchard, garden,
nursery or greenhouse. From the Latin: Hortus (garden) and cultus
(tilling)
Classification by Use EDIBLE Fruits Tree fruits Small fruits
Vegetable Warm season Cool season Herbs Culinary Medicinal Nuts
ORNAMENTAL/LANDSCAPE Woody Plants Trees Shrubs Vines and ground
covers Herbaceous Plants Flowers Vines and ground covers Grass
Slide 5
Classification by Temperate Requirement Tropical plants vs.
Temperate-zone plants Warm vs. Cool season plants Tender vs. Hardy
plants Long day vs. Short day plants Cold hardiness zone
plants
Slide 6
Classification by Ecological Adaptation Alpine Prairie
Ponderosa pine forest Pinyon/Juniper forest Riparian Xeric
(dry)
Slide 7
Classification by Taxonomy Plant Kingdom divided into two
groups: Non-vascular plants Vascular plants Nearly all plants in
the garden are vascular
Slide 8
Classification by Taxonomy Gymnosperms Do not have true flowers
Seeds are enclosed in fruits Most seeds are produced in cones
Slide 9
Classification by Taxonomy Angiosperms Produce flowers Develop
fruits that contain seeds Can be divided into monocots and
dicots
Slide 10
Classification by Taxonomy
Slide 11
Plant Evolution
Slide 12
Classification by Stem and Leaf Texture Herbaceous plants Woody
plants Deciduous plants Evergreen plants Broadleaf Narrowleaf
Grass-like Bee Balm, Herbaceous/non-woody stems Butterfly Bush,
Woody stems Deciduous plants shed their leaves every year Evergreen
plants hold their leaves year-round Corn is a good example of
broadleaf Narrow leaf lavendar
Slide 13
Classification by Life Cycle Annuals Biennials Perennials
Slide 14
PLANT PARTS Roots Stems Leaves Fruits Flowers Seeds
Slide 15
Roots Absorb water and nutrients from soil Anchor the plant
Provide support for stem Store sugars and starches (needed for
photosynthesis) Source of winter survival for perennials Fibrous
roots vs. Tap roots
Slide 16
Stems Connects roots to leaves Supports buds and leaves Phloem
and xylem serve as channels in the stem for carrying water,
minerals, and sugars to other plant parts. Xylem brings water up
the stem, and Phloem sends water down. Stems grow above or below
the ground.
Slide 17
Leaves Absorb sunlight energy to make food through the process
of photosynthesis Take up carbon dioxide and release oxygen Store
energy Control water through transpiration Simple or compound
Photosynthesis water + CO 2 sugar + O 2
Slide 18
Flowers Showiest part of plants; fragrant and/or colorful to
attract pollinators Important for sexual reproduction Self
pollinating or cross pollinating
Slide 19
Fruit Part of the plant that surrounds one or more seeds Spread
seeds Attracts animals to help spread seeds
Slide 20
Seeds Contain the information needed for a new plant to grow
Embryo Endosperm Seed coat
