Pollination & Fertilization
Mrs. Taylor
6th grade Science
In the Life Cycle of a
Flowering Plant
there are two very
important processes –
Pollination &
Fertilization.
Pollination
During the process of pollination a
pollen cell (male sex cell) from the
anther of the stamen must be moved
to the stigma of the pistil.
Pollination Diagram
The Red arrow shows
the pollen from the
anther moving to the
stigma (top of) the
pistil. This movement
of pollen is called
Pollination.
Pollinators
Pollination occurs with the help of
Pollinators like….
• Bees
• Butterflies
• Birds
• Other insects
Wind also helps pollination occur by carrying
pollen from one flower to another
Fertilization
Once the pollen has been moved to the
stigma and pollination has occurred the
process of Fertilization can begin.
Fertilization
• First a pollen tube is created that allows the
pollen to move down the style of the pistil to
the ovary.
• Once in the ovary the pollen cell ( male sex
cell) can join with the ovules (female egg
cell). The joining of these two sex cells is
called fertilization.
• Once the ovule is fertilized a seed will
develop!
