test Flashcards
vascular
plants that use roots and stems to take in water and nutrients
non vascular
plants that don’t use roots and stems
angiosperms
also known as flowering plants
seeds protected by ovule
gymnosperms
‘naked seed’
seed not protected by ovule
herbaceous
fleshy stem
woody
stems are covered by bark
grasses
slender leaves
send out rhizomes to reproduce
most general level of classification
domain
most specific classification
specific
phylogeny
the evolution of a particular species as, as new things develop/evolve, species have evolved
nomenclature
formal scientific naming of plants
taxonomy
science of naming organisms based on groups
sexual repro
2 parents contribute genetic info to produce a unique offspring genetically different from their parents’
requires fusion of male cells in the pollen grain with female cells in the ovule
how does being immobile affect the plant’s ability to reproduce
they need to rely on outside sources
pollination
the transfer of pollen from the male organ of a flower to the female organ
fertilization
the union of sperm and egg which occurs deep inside the flower after pollination
cross pollination
the pollen from one flower is carried to the stigma of another flower from the same variety
4 parts of the female reproductive system
stigma
style
ovary
ovule
one whole female reproductive unit is called a —-. numerous carpels are called a —-
carpel
pistil
stigma
part of the pistil where the pollen lands and germinates
style
a long tube on top of the ovary and below the stigma
ensures the pollen makes it to the ovule
ovary
at the base of the pistil
produces ovules
ovule
part of the ovary that contains the seeds
male repro organ
stamen
2 parts of stamen
anther
filament
the stamens typically corresponds with the number of
petals
anther
part of the stamen that produces and contains pollen
sits on top of the stalk
filament
long hair-like stalk that the anther sits on top of
petals
attracts pollinators
sepal
green leaf-like parts below petals
protects flower bud
receptacle
thickened part of stem on which the flower organ grows
perfect flowers
all female or all male but not in the same flower
imperfect flower
have both female and male parts in the same flower
complete flowers
have all the parts of a flower
when talking about species; plants with increase in number…
increase in similarity
stem
transports water and nutrients though
roots
uptake nutrients and water
anchor plant
flowers
reproductive organ
leaves
photosynthesis
vascular tissues
xylem and phloem
xylem
transports water an nutrients from the roots
goes up
dead
pholem
carries glucose and ate made in photosynthesis throughout the plant
goes down
alive
asexual reproduction
new plant formed using the host/parent plant in some way
double fertilization
when 1 pollen grain travels down a tube created by the tube cell and meets with an ovule. 1 sperm makes embryo and the other becomes the seed coat
4 ways to propagate a plant
grafting
air layering
ground layering
cuttings (root, stem, leaf)
why are fruit trees grafted
allows tree to have a good root system and have good fruit
grows can be selective
perfect plant to grow well and produce fruit
hormodin
initiates root growth
photosynthesis
allows plant to produce food and thus energy
transpiration
to get water
respiration
makes plant self-sustaining
allow plant to get food (energy) at night
Scientific name: Poinsettia
Euphorbia pulcherrima (underline)
Poinsettias are native to:
Mexico
“Poinsettia Day”
December 12
How many varieties of Poinsettias?
over 100
Poinsettias contribute over— to the US economy at the retail level
$250 million
Poinsettias are the — in the US and Canada
best selling potted plant
5 cultivars of poinsettias that we grow at school
Prestige Red, Freedom Red, Marblestar, White Star, Autumn Leaves
4 parts of a poinsettia
Bract, Transition bract, cyathia, leaf
Wholesale growers supply — rooted cuttings
2 1/4”
poinsettia production
hard pinch
drop bracts after flowering, so its important to get timing down
6.5” pot =
1 plant
12” x 12” spacing
8” pot =
2 plants
18” x 18” spacing
10” pot =
3 pots
24” x 24” spacing
poinsettia growing requirements
Photoperiodic plants, temperatures, watering (minimal & avoid leaves), fertilizers
best poinsettia practices
marathon for insects (most commonly white fly)
1/2 tsp per 6.5” pot and 8” pot
1 tsp per 10” pot
minimal water for poinsettias to avoid diseases:
Stem and Root Rot
Botrytis Blight
Powdery Mildew
Viruses
