hortus cultura
garden cultivation
horticulture
science and art of cultivating, processing, and marking fruits, vegetables, and ornamental plants.
pomology
fruit and nut production, “apple or fruit”
Olericulture
vegetable production, “pot herb”
3 primary areas of study
pomology, olericulture, ornamental

Liberty Hyde Bailey
Father of Horticulture, 1858 - 1954

binomial nomenclature
genus and species, capital then lowercase, all italicized
Carolus Linnaeus
1707 - 1778, swedish botanist, introduced binomial nomenclature, first botanist to organize plants into classes based on floral structure.
Species Plantarum
first plant naming guide
ICBN

Cultivar
Product of plant breeding or selection (cultivated variety). In quotes, nonitalicized
Inter-specific hybrids
magnolia x soulangeana
Inter-generic Hybrids
X Fatshedera lizei
Histology
microscopic plant structure
Robert Hooke
discovered cells
Prokaryotic Cells
SIngle cell organisms, lack distinct nucleus due to absence of a nuclear membrane (eg. bacteria)
Eukaryotic Cells
Made up of compartments bounded by membranes each with specialized structures and functions
Eukaryotic Cells - components
Protoplast, Nucleus, Cell Wall
cytoplasm
viscous liquid coposed of matrix proteins contained by the plasma membrane
Protoplast
contains all the organelles in cytoplasm bound by a plasma membrane which is enclosed by a cell wall
plastid - leucoplast
store oil, starch and proteins
chromoplasts
plant pigments
chloroplast
contain plant pigments, including chlorophyll, which is the site of photosynthesis
mitochondria
site of respiration, ATP production
respiration
release of energy stored in carbohydrates from photosynthesis for cellular activity
cell wall
protects protoplast, provides structure
plasmodesmata
connect one cell to another by cytoplasm strands through the cell wall in openings called pits
Nucleus
contains DNA
Vacuole
up to 90% of cell volume, dissolved materials
meristematic tissue
actively dividing cells taht differentiate into other tissues, roots and shoot tips
permanent tissues
differentiated cells, divided into simple and complex tissues
apical meristem
end of shoots
opposite meristem
meristem across from each other
alternate meristem
meristem alternate side to side along stem
whorled meristem
meristem are close together to form a spiral
root meristem
tip of root
tap root
main root with a few lateral roots
fibrous root
branches of roots in all directions
subapical meristem
produces new cells in the region a few micrometers behind an active shoot. Tru meristem in that it produces leaves in a rosette form ie) beets carros
lateral meristem
produces secondary growth often called the vascular cambium producing new xylem and phloem. Cork cambium, etc. Growth rings in woody plants.
simple tissues
uniform, contain 1 kind of cell
parenchyma
found in herbaceous plants, flesh of fruit, swollen roots, succulents. Then-walled cells with large vacules found under the epidermal cells, contain chloroplast and can become meristematic to heal wounds
Collenchyma
cells thickened by cellulose - primarily in young stems, leaves and veins of leaves
Sclerenchyma
thick walled cells found as lignified fibers throughout the plant. Protoplast dies and becomes nonliving, found in stems and bark
epidermis
outermost layer of cells, absent from apical and root meristems
stomata
primarily regulates movement of water and gas in and out of the plant
secretory tissue - outside plant
nectaries, osmophores, digestive glands, adhesive cells
secretory tissue - inside the plant
resin ducts, mucilage cells, oil chambers, laticifers
xylem
conducts water and dissolved minerals from roots to all parts of the plant
phloem
conduct food and metabolites from leaves to stems flowers, fruit, roots and storage organs
xylem components
tracheids, vessels, fibers
phloem
sieve cells - no sieve plate, gymnosperms. Sieve plate and companion cells, angiosperms
monocots/monocotyledons
grasses and grass-like plants
dicotyledons/dicots
broad-leaved plants
cotyledon
seed leaves
plant organs
stems, buds, leaves, roots, flowers, fruit, seed
stems
vascular tissue, mechanical support
transpiration
water loss through stomata
