4. Homework
Textbook p 313

5. GLE’s
GLE Compare and contrast the fundamental features of sexual and asexual reproduction.
GLE Demonstrate an understanding of sexual reproduction in flowering plants.

6. Types of Reproduction
Asexual
Sexual

7. Purpose of Reproduction
To make sure a species can continue.
Definition: Reproduction is the process by which an organism produces others of its same kind.

8. Asexual Reproduction
A new organism (sometimes more than one) is produced from one organism.
The offspring will have hereditary material uniform with the hereditary material of the parent organism. This means they will be genetically alike.

9. Types of Asexual Reproduction
Budding
Regeneration
Fission (Binary fission)

10. Budding
Process by which a new, duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created.
Very common in plants;

13. Regeneration
The ability to restore lost or damaged tissues, organs or limbs.
It is a common feature in invertebrates, like worms and starfish.

16. Fission Also called binary fission.
Becoming two by division of the complete organism.
A type of cell division.

19. Sexual Reproduction Requires two sex cells (gametes)
The gametes join to form an entirely new organism
Different from the parent organism
Genetically similar to parents

20. IMPORTANT!
Asexual reproduction results in offspring that are genetically identical to the parent organism
Sexual reproduction results in offspring that are genetically different from the parent organisms

21. What is the function of the flower?
The flower helps the plant to reproduce.
flower

22. The Parts of a Flower Most flowers have four parts: sepals, petals,
stamens,
pistil.

23. The parts of a flower Sepals protect the bud until it opens.
Petals attract insects.
Stamens make pollen.
pistil grows into fruits which contain the seeds.

24. Flowers have male and female parts pistil stamen
This is the name for the FEMALE part of the flower.
pistil
stamen
This is the name for the MALE part of the flower.

25. The pistil
(female part)
stigma
style
ovary

26. The stamen
(male part)
anther
filament
pollen

27. The parts of a flower
pollen
stigma
anther
style
filament
ovary

28. Label your flower diagram
Label the following parts on your diagram…
the stamen
the pistil
stigma
style
ovary
anther
filament
pollen

29. What have we learned today?
We can label the parts of a plant and flower.
We know that plants produce flowers which have male and female organs.
We know that seeds are formed when pollen from the male organ fertilizes the female organ.

30. Later this week...
We will find out more about how flowering plants reproduce.
We will also find out that insects pollinate some flowers and discover how this is done!

31. Science Closure
The diagrams represent the way that three different organisms reproduce. Which of these classifies the reproductive method of all the organisms shown above?
A segmentation
B budding
C asexual reproduction
D sexual reproduction
