LOUISIANA HORTICULTURE TEST STUDY GUIDE COMPLETE #7
What is the difference between a cultivar and variety? - correct answer Cultivar- A plant
or grouping of plants selected for desirable characteristics that can be maintained by
propagation
Variety- A naturally occurring subgroup of a species which has some distinguishing
characters
Who is Linnaeus? What system of naming plants did he create? - correct answer
Linnaeus is a Swedish Botanist who developed the Binomial System of
Nomenclature(Genus + Species)
Why is it important to know common and scientific names of plants? - correct answer So
that you can communicate with others without confusion about the identity of a plant
What are some origins of botanical names? - correct answer Country of origin, Names
of Explorers, and Descriptive Latin Terms
What are some typical groupings for plants when they are classified by growth
characteristics? - correct answer Life Span, Leaf Retention, Growth Habits, Light, Size
List the functions of a root system. - correct answer Absorption, Anchorage, Conduction,
Storage
What are two kinds of root systems? - correct answer Fibrous and Taproot
List the functions of the stem of a plant. - correct answer Support; Conduction; Storage
Define xylem and phloem. - correct answer xylem- the transport vessel for water and
minerals from root to leaf
Phloem- the transport vessel for manufactured food from leaf to stem
What is the difference between monocots and dicots? - correct answer monocots-
plants that have a single seed leaf(corn; grass; lilly)
Dicots- plants that have two seed leaves(trees; shrubs; annuals)
What are nodes and internodes? - correct answer nodes- the area on stems where
leaves emerge
Internodes- the area on stems in between where leaves emerge
List the types of specialized stems and roots commonly found in plants. - correct answer
Bulbs; Corms; Rhizomes; Tubers; Tuberous Roots
, What are the two main functions of leaves? - correct answer Photosynthesis and
Transpiration
Define angiosperms and gymnosperms. - correct answer Angiosperms- plants that
bloom and develop fruit which encloses the seed
Gymnosperms- plants that have no true flowers or fruit, but make seeds in cones

How is light intensity commonly measured? - correct answer Foot Candles: The amount
of light falling on one square foot one foot away from a standard candle
List three functions of water in a plant. - correct answer 1)Ingredient of Photosynthesis
2)Solvent for nutrients
3)Gives the plant tissue rigidity
Define permanent wilting point. - correct answer when all gravitational water and the
available water are gone and only the graivable water remains
