/.Agronomy: - Answer-✅science and technology of culturing, utilizing and improving
field crops (grain, fiber and forage crops).
/.Horticulture: - Answer-✅science, technology and art of culturing, utilizing and
improving fruit, vegetable, flowering and ornamental plants.
/.What are the areas of horticulture? - Answer-✅Olericulture, Pomology, Ornamental
Horticulture, and Turf
/.Olericulture: - Answer-✅vegetable culture and production
/.Pomology: - Answer-✅fruit and nut culture and production
/.Ornamental Horticulture: - Answer-✅plants grown for aesthetic uses, improvement of
quality of life and our environment, and functional uses (ex. energy conservation).
/.Turf: - Answer-✅grasses for lawns, sport facilities, landscapes and golf courses (in
Agronomy in many Universities)
/.What are the areas of Ornamental Horticulture? - Answer-✅Floriculture, Floristry,
Nursery Production, and Landscape Horticulture
/.Floriculture: - Answer-✅flowering and foliage plant culture and production
/.Floristry: - Answer-✅floral design and retail floristry operation
/.Nursery Production: - Answer-✅tree, shrub and vine culture and production
,/.Landscape Horticulture: - Answer-✅exterior and interior design, construction and
maintenance of landscapes
/.What are the classical guidelines for placement of a crop in horticulture, agronomy or
forestry? - Answer-✅* Intensity of Production
* Purpose Crop is Grown
* Tradition or Custom
/.What are the organs of a plant? - Answer-✅*Flower
*Leaf
*Stem
*Root
/.What are the tissue systems of a plant? - Answer-✅*Dermal
*Vascular
*Ground or Fundamental
/.What is the function of the dermal tissue system? - Answer-✅protection from the
environment and water loss
/.Which tissues are a part of the dermal tissue system? - Answer-✅*epidermis
*periderm or bark
/.Epidermis: - Answer-✅single layer of cells on primary (herbaceous) plant parts
/.Periderm or Bark - Answer-✅a corky tissue that replaces epidermis on secondary
(woody) plant parts
/.What is the function of the vascular tissue system? - Answer-✅conduction of water,
nutrients, sugars and hormones throughout the plant
/.Which tissues are a part of the vascular tissue system? - Answer-✅*xylem
*phloem
/.Xylem: - Answer-✅conducts water and nutrients up roots, stems and leaves
/.Phloem: - Answer-✅conducts water, sugar, hormones, etc. down and up roots, stems
and leaves; moves from where produced (called sources) to where needed (called
sinks)
/.What is the function of the ground or fundamental tissue system? - Answer-✅storage,
support, filler tissue and site of photosynthesis
, /.Which tissues are a part of the ground or fundamental tissue system? - Answer-
✅*cortex
*pith
*mesophyll
/.Cortex: - Answer-✅outer region of stems and roots
/.Pith: - Answer-✅center of stems
/.Mesophyll: - Answer-✅middle of leaves and flower petals
/.What are the 3 basic cell types that comprise most of the tissues of plants? - Answer-
✅* Parenchyma
* Collenchyma
* Sclerenchyma
/.Parenchyma: - Answer-✅* thin, non-lignified primary cell walls
* filler, storage, protection, photosynthesis
*examples: flesh of potato, lettuce leaf
(ISODIAMETRIC)
/.Collenchyma: - Answer-✅* unevenly thickened, non-lignified primary cell walls
* support in growing tissues
*example: strings in celery stalks
(LONGER THAN WIDE)
/.Sclerenchyma: - Answer-✅* evenly thickened, lignified (tough) secondary cell walls;
dead at maturity
* support in mature tissues
* examples: fiber - bamboo cane, sclereid - seed coat, stone cell - pear fruit
(FIBER-LONG, SLENDER, POINTED ON ENDS. SCLEREID OR STONE CELL-
MULTI-SHAPED, OR COLUMNAR)
/.What are the components of a cell? - Answer-✅*cell wall
*plasmalemma or plasma membrane
*plasmodesmata
*cytoplasm
/.Polysaccharide: - Answer-✅a polymer or chain of sugars
/.Cellulose: - Answer-✅forms a matrix of microfibrils (chains of B-1, 4-linked glucose)
/.Hemicellulose: - Answer-✅filler between cellulose microfibrils (chains of misc. sugars)
