chapter23C_Angiosperms Flashcards
angiosperms distinguishing characteristic
flowering plants
most successful plant group
angiosperms
why are angiosperms so successful
number of seeds produced and speed of reproduction through pollinators
Peduncle
flower stem
Receptacle
flower foundation, inside peduncle
Calyx
sepals together, protects bud, supports petals
Corolla
petals collectively together
Coralla uses
attracts insects through emitting odor
male reproductive part of angiosperms
stamen
Filament role male Angiosperm
supports anther
Anter role male Angiosperm
where pollen is produced
Angiosperm female reproductive structure
carpel
Stigma role female angiosperm
nectar secretion, catches than activates pollen with enzymes from nectar
Style role female Angiosperm
supports stigma, opens upon ova maturation
Ovary role female Angiosperm
ova location, ova turns to seed and ovary turns to fruit
most fruits, vegetables, and trees are _dicot
eudicot
grasses and grains are _cot
monocot
Where do Eudicot and Monocots differ
seeds, stems, Roots, flowers, leaves
number of Eudicot flower petals
groups of 4 or 5
number of Monocot flower petals
groups of 3
vascual bundle
xylem and phloem
leaf differences between Eudicot vs Monocot
branching vs parallel veins
stem differences between Eudicot vs Monocot
vascular bundle (xylem/phloem) circular aroud stem, vascular bundle randomly across stem
root differences between Eudicot vs Monocot
vascular bundles located in the center of tap root, vascular bundles circular in fibrous root
seed germination differences Eudicot vs Monocot
2 cotyledons vs 1 cotyledon
Phylum Anthophyta common term
Flowering Plants
Where does pollen leave from on the flower
anther
Where does pollen enter on the flower
stigma
When does fertilization begin?
nectar enzymes on the stigma induce germination on the pollen
After pollen is induced to germinate, what happens next?
pollen tube having 2 sperm nuclei grow through style toward ovary
what do 2 sperm form upon fertilization completion?
one sperm fuses with egg nucleus to create diploid zygote, other sperm fuses with 2 egg nuclei to create triploid endosperm cell
what do the endosperm form
cotyledons
Eudicot seeds are divided in half between the _
cotyledons
in an apple, fertilized eggs become the _, and the fruit comes from the _
seeds, ovary
what is the bee orchid flower labellum
flower structure that imitates female bee instead of providing nectar for pollination
