Ch. 23 Seed Plants II: Angiosperms
Changing Concept about early angiosperms
ranalean flower
Magnolia-type flower
relictual
generalized
flower w all parts
sepals, petals, stamens, carpels
parts arranged spirally
Classification of Flowering Plants
eudicots
reticulate venation
vascular bundles in ring of stem
two cotyledons
be woody, herbaceous, succulent
flower parts group in five or four
basal angiosperms
early angiosperms diverged into
monocots
#
have one cotyledon on embryo
leaves have parallel veins
vascular bundles distributed through stem
secondary growth & wood
flower parts group in threes
Basal Angiosperms
#
ex. Nymphaeaceae
water lilies
uniaperturate
pollen grains have a single germination pore
Monocots
Alismatales
ex. aquatic herbs
ex. aquarium plants
no transpiration
air chambers provide buoyancy
partly or entirely submerged
liliales
Asparagales
spots or lines on petals
septal nectaries
Liliaceae
ornamental plants
Colchicaceae
source alkaloid colchicine
prevents microtubule polymerization
tepals
perianth members
looks so similar
Asparagales
septa
carpals fuse side by side
septal nectaries
open areas secrete nectar
Commelinoid Monocots
unique types of epicuticular wax
unusal hemicellulose
unusual ultraviolet florescent compounds
pollen & endosperm contain starch
Arecales
palms
simple leaves fully expanded
solitary trunk
Poales
contain most foods
wheat, barley, oats, rye
corn, rice, sugar cane
Zingiberales
most familiar house plants
Eudicots
Basal Eudicots
Caryophyllales
betalains
water-soluble pigments
in Caryophyllales
perisperm
nutritive tissue
nucellus cells proliferate
anthocyanin pigments
#
pigements in flowers
not produced by Caryophyllales
Rosid Clade
fabids
eurosids I
malvids
eurosids II
no high relictual features
pinnately compound leaves
Asterid Clade
#
most derived large clade
ex. sunflowers, periwinkle, petunia
stamen alternate with petals
sympetalous flowers
few stamens
not more than petal lobes
sister clades
different types of pigements
used to be grouped together as dicots
differences between monocots and eudicots
