Pollination

Pollination Fertilization

• Mrs. Taylor
• 6th grade Science

2
In the Life Cycle of a Flowering Plant there are
two very important processes Pollination
Fertilization.
3
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.
5
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

6
Fertilization

• Once the pollen has been moved to the stigma and
  pollination has occurred the process of
  Fertilization can begin.

7
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!
