perianths
the male part
stamen
the female part
carpels
lobes containing pollen sacs
anther
stalk that holds the anther
filaments
receive the pollen
stigma
supports the stigma
style
contains ovules that tore the female gametes
ovary
located inside the ovary
ovules
protective layer surrounding the ovule
integuments
inner structure of the ovule that develops into endosperm
nucellus
produces the egg cells for fertilization which develops into the seed
embryo sac
opening that allows the pollen to enter the ovule
Micropylar end
opposite of micropillar end where nucleus is rejoined by integuments
chalazal end
cells that have no established function but has deemed to undergo programmed cell death during embryo sac maturation prior to fertilization
antipodals
produce signals that guides the pollen
synergids
responsible for double fertilization
polar nuclei
composed of a thimble-shaped mass of parenchyma cells
pollination
4 types of pollination
self-pollination
cross-pollination
wind pollination
animal pollination
same flower or another flower of the same plant
self-pollination
flowers from different plants
cross-pollination
contains microgametophytes of seed plants
pollen grains
fusion of gametes
fertilization
group of several flowers that may all open at the same time
