2 Pollination & Fertilization Mrs. Taylor 6 th grade Science

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

4 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.

5 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.

6 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

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

8 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!

9 Watch fertilization in action!

10 Watch this video clip to review the parts of a flower, pollination, and fertilization.

11 It is Quiz time If you dont feel ready yet and would like to review one more time click here to return to the start of the presentation. If you are ready click here.

12 Question #1 When pollen is moved from the anther to the stigma it is called? FertilizationPollination

13 Question #2 Which of the following are not pollinators? BirdsBees Wind Cats

14 Question #3 The joining of the female sex cell (the ovule) and the male sex cell (the pollen cell) is called? FertilizationPollination

15 Question #4 What forms to allow the pollen to move to the ovary? Pollen TubeEgg SeedAnther

16 Question #5 What forms after the ovule is fertilized? Pollen TubeEgg SeedAnther

17 #1 Correct! 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. Back to Quiz
