1. Plant Sexual Reproduction
Process of Making new Plants

2. Essential Standards
6.L.1 Understand the structures, processes and behaviors of plants that enable them to survive and reproduce.

3. Clarifying Objectives
6.L.1.1 Summarize the basic structures and functions of flowering plants required for survival, reproduction and defense.

4. Essential Questions What are the basic structures of flowering plants?
What purpose does each of these structures serve?

5. Pollination Process

6. Flower
Reproduction or creating new plants occurs (happens) in the flower part of a plant
In the lesson we will learn the process of plant reproduction

7. Flower (Male) The male part of the flower is called the Stamen
The stamen contains two parts called
Filament
Anther
The Anther produces the Pollen Granules which contains the SPERM

8. Flower (Female) The Female part of the plant is called the Pistil
The Pistil is made from 4 parts
Stigma
Style
Ovary
Ovule

9. Essential Questions Get with a partner and answer…
What are the basic structures of flowering plants?

10. Insect is Attracted (Petal)
The Petal of the flower has a very important purpose
The Petal is colorful & smells good because it is meant to attract an insect
Bee lands on the flower and gets pollen from the Anther stuck to his feet (Male)

11. Bee Flies to another Flower
The bee then flies to another flower looking for some nectar to eat
When he lands the pollen on his feet is dropped onto the Stigma of the plant (Female)

12. Pollen Roles down the Stigma
The Pollen contains the sperm which will later fertilize the egg (seed) of the plant
The pollen roles down through the STYLE and into the OVARY
From the OVARY it finds its way into the OVULES where the egg is awaiting fertilization
POLLINATION is the process by which pollen moves from the STAMEN to the PISTIL

13. Fertilization Occurs
When the pollen touches the egg inside the Ovule FERTILIZATION of the egg occurs and the egg starts growing
The egg grows into a SEED as the plant develops

14. Essential Questions Get with a partner and answer…
What purpose does each of these structures serve?

15. The Wind Blows The wind starts blowing and blows the seed into the air
Wind dies down and the seed drops down into the ground

16. The Rains Come
As the rains begin to fall the seed becomes wet and small ROOTS come out of the seed and go into the ground
This is called GERMANATION

17. The Plant Grows Up
The plant grows up and develops into an adult plant and the process repeats itself

18. FUN FACTS
The seed of the flower depending on what kind of plant it is can develop into a fruit (orange tree)
Then the fruit will contain the seeds
When fertilization of an egg takes place it creates a WHOLE NEW ORGANISM
The time of year (summer, spring, fall or winter) a plant flowers depends on the amount of SUNLIGHT or DAILY HOURS OF DARKNESS during the season (most plants flower in the summer because there are more hours of sunlight)
If you are trying to prevent reproduction of a plant all you need to do is cut off the MALE PART or FEMALE PART of the plant

19. EOG Questions
How does the anther help with reproduction of a flowering plant?
A) It develops into a fruit after fertilization occurs.
B) It moves pollen to the roots of the plant.
C) It grows the seeds for the plant.
D) It produces and stores pollen.

20. Important Points
Insects transport pollen from one plant to the Pistil of another plant
When the pollen (sperm) meets the Ovule (where the egg is kept) FERTILIZATION occurs
Seeds develop after the egg is fertilized
Seeds grow roots and stick in the ground through a process called GERMANATION
