Plant Reproductive Structures Flashcards
protect the flower bud; pollinators attractors
petals and sepals
supports the flower and connects the flower to the rest of the flowers; the floral base
stem and receptacle
produces pollen grain; contains male gametes
anther
stalk that supports the anther
filament
sticky tip that traps pollen
stigma
long slender structure connecting the ovary to the stigma
style
contains ovules that produces female gametes which develops into a seed when fertilized
ovary
both male and female organs are in one individual
monoecious
male and female organs are on separate individuals
dioecious
the outer part that envelop a developing bud; these part are frequently green and leaf-like
calyx/sepal
sepals free
polysepalous
sepals joined
gamosepalous
a sterile floral component that typically serves as a visually striking aspect of a flower
corolla/petals
in this, the stamens in a flower remain free
polyandrous
in these, the stamens are united into one bundle
monadelphous
these have the stamens united into two bundles
diadelphous
the stamens are united into more than two bundles
polyadelphous
these have only one carpel
monocarpellary
these have more than one carpel
multicarpellary
when carpels are free
apocarpous
when carpels are fused
syncarpous
located above the attachment points of other floral parts
hypogynous flower
located below the sepals, petals, and stamens
epigynous flower
half superior, half inferior
perigynous flower
the stalk of an inflorescence
peduncle
the stalk of an individual flower; supports an individual flower, it connects the single flower to the inflorescence
pedicel
a flower without a stalk or pedicel
sessile flowers
when parts of each floral set is the same and size
actinomorphic (radial symmetry)
when some parts of one or more floral sets differ in shape or size from other parts of the same floral sets
zygomorphic (bilateral symmetry)
ovules are borne on placentae on the central axis of a compound ovary
axile placentation
has a single ovule that is almost at the base of the ovary
basal placentation
the ovule is borne along the fused margins of the placenta of a single ovary
marginal placentation
ovules are born in placentae located on the inner surface of the outer wall of the ovary
parietal placentation
ovules are borne on placentae on a free, central column within an ovary that has only one locule
free central placentation
