Flowering Plants
A flowering plant has both male and
female parts.
The female
part is called
the pistil.
The male part
is called the
stamen.
Stamen: The male reproductive
structure of a flowering plant
Anther: the structure located on top
of the stamen and carries the
pollen
Pollen
Pollen is the male sex cell that donates half of
the DNA to make a seed.
It is a powdery substance, usually orange
or yellow in color, that gets carried by
pollinators.
Filament: a thread-like part that
holds up the anther
Pistil: the female reproductive
structure of a flowering plant
Stigma: the sticky surface on the
top of the pistil; it traps and holds
the pollen
Style: the tube-like structure that
holds up the stigma
Ovary: the plant part at the bottom
of the flower that has ovules inside
(this turns into the fruit and seeds we eat)
Ovules: the female sex cells inside
the ovary that donate half the DNA
to become the seed
(They become the seeds when pollinated or fertilized by the pollen.)
A baby seed! 
Petal: the colorful flower
parts that surround the
reproductive structures
Sepal: the green petal-like parts at
the base of the flower; they help
protect the bud when it develops
Perfect: flowers that have both male
and female parts (ex. Roses, lilies,
and pea plants)
Imperfect: flowers with male or
female parts (ex- cucumbers,
pumpkins, and melons)
Pollination: when pollen moves from
the male parts to the female parts
Pollination is the step before
fertilisation in plants. Fertilisation
is when the male and female
gametes join to form an embryo.
