Floric-flowering and foliage plant culture and production

Floristry-floral desgin/retail

Nursery Prod-tree,shrub and vine culture and production

Lands Hort-exterior and interior design of landscapes
Organs in plants (4)
flower (reproductive)
leaf stem root
Tissue Systems in plants (through each organ)(3)
Dermal (outer)
vascular (veins, organs)
ground or fundamental (everything in between)
Dermal Tissue System
protection

epidermis-single layer of cells on primary herbaceous plant parts

periderm(bark)-corky tissue on secondary plant parts
Vascular Tissue Center
conducts nurtients throughout plant

xylem- conducts UP roots stems leaves
Phloem- conducts DOWN and UP, from sources to sinks (where needed)
Ground or Fundamental tissue system
Storage, support

cortex-outer region of stems/roots
pith-center of stems
mesophyll-middle of leaves and flower petals
3 basic cell type compsise most of the tissues of plants
Parenchyma

collenchyma

sclerenchyma
Parenchyma
thin, non lignified, filler, storage, protection, photosynthesis, simplest, type we eat, isodiametric [ ]
collenchyma
unevenly thickened, non lignified primary cell walls, support in growing tissues (strings in celery) longer than wide
sclerenchyma

2 types
evenly thickened, secondary cell walls, support in mature tissue

fiber (long slender pointed @ ends)bamboo cane

sclerid or stone cell(multi shaped or columnar)scler- seed coat, stone- pear fruit
Animal cells lack
cell wall

plastids
cell wall herbaceous (primary tissue)
no lignin

kind we eat
cell wall - secondary
lignin

xylem and schlerenchyma cells
polysaccharide
chain of sugars
cellulose

hemicellulose

pectin
polysaccharides
c-forms matrix of microfibrils
h-filler between cellulose micrifibrils
p-cenemting agent high in middle lamella (chains of galacturonic acid)
lignin (also in cell wall along with polysaccharides)
tough polymer high in secondary cell wall
protein
mainly structural (hydroxyproline)
plasmalemma (plasma membrane)
surrounds cytoplasm, selectively permeable, composed of a layer of phospholipids and proteins
plasmodesmata
tubular plasma membrane extensions through cell walls connect adjacent cells
cytoplasm
cytosol & organelles
cytosol
fluid portion of cytoplasm
nucleus
-chromosome
-nucleolus

mitochondrion
nucleus-location of DNA and some RNA
-chromo-coils of DNA
-nucleolus-ribosome synthesis

mito-respiration, power house
plastid
-leucoplast
-chromoplast
-chloroplast
double membrane bound bodies for storage and photosyn.
-l-colorless...amyloplast-starch storage...elaioplast-fat and oil storage
-chromo-colored plastids storage of carotenoids(orange and yellow)
-chloro-green plastids containing chlorophyll
endoplasmic reticulum

ribosome

vacuole
-tonoplast
ER-tubular membranes for communication site of protein and membrane synthesis
ribo-spheres of RNA protein synthesis occurs on surface
vac-storage...anthocyanins(blue red purple pigments)
-tonoplast-membrane surrounds vacuole
golgi body (dictyosome)

microbody

microtubule
GB-disk shaped membranes for membrane synthesis and polysaccharide synth.

microbody-membrane bound storgae bodies

microtubule-tubular rods used in mitosis and cellulose orientation in cell walls
structure of starch v cellulose
starch - up cellulose- down
flipped glucose molecules
we can't eat cellulose bc we have no enzymes to break it down
base pairing of nucleic acids

DNA

RNA
AT
GC

AU
GC
gene

protein

enzyme
g-length of DNA
p-polymer or chain of amino acids
e-protein that acts as a metabolic catalyst(workers canonly do 1 simple task)
sequence of amino acids determines
shape. sequence of nucleotides in DNA determines sequence of necleotides in RNA and determines the sequence of amino acids in protein which determines what kind of enzyme it is(what kind of work it does)
Each gene contains insctructions on how to build
1 enzyme
GMO
genetically modified organism (tomato)
