1. Reproduction

2. What’s the difference?
Asexual
Sexual

3. MITOSIS
We will be learning about mitosis in the next few days… but for now you should know it is the process that allows cells to reproduce asexually

4. Mitosis in Organisms Mitosis is the asexual reproduction of cells
Mitosis happens in all organisms except bacteria.
For a multicellular organisms it allows them to grow, heal, and repair damaged cells.
For a unicellular organism it allows them to reproduce clones

5. Mitosis and Types of Asexual reproduction
All types of Asexual reproduction we will be talking about today (except the type with bacteria) is made possible by mitosis

6. Brief overview of Mitosis
Cell duplicates its DNA
Cell Grows
Cell Splits
Two IDENTICAL cells are formed

7. Mitosis What is it? Who does it? What is the product
The asexual reproduction of body cells
Who does it?
Single celled eukaryotes
Eukaryotic organisms to grow and heal
NOT PROKARYOTES
What is the product
Genetically IDENTICAL cells (full set of chromosomes)
CLONE of original cell

8. Meiosis

9. MEIOSIS Meiosis is the asexual reproduction of sex cells
Sex Cells= Gametes
Sperm and Eggs
Different from Mitosis because mitosis produces body cells with full set of chromosomes
In Meiosis the amount of DNA is NOT duplicated before the split. When cells divide the genetic material is cut in half (TWO HALVES MAKE A WHOLE)

11. Meiosis What is it? Who does it? What is the product
The asexual reproduction of sperm and egg
Who does it?
Any organisms that produces sexually
What is the product
Genetically UNIQUE cells with half the amount of DNA as an adult cell

12. Type: Binary Fission

13. Binary Fission
Single cell organisms grow and split making a new creature (clone)
New cell and parent are identical (same size, exact copies)

14. What’s your bacteria up to?
Binary Fission is a VERY FAST EFFICIENT PROCESS::
One single cell of E.coli can become 10,000,000 in 12 hours if in favorable conditions

15. Binary Fission
EVENTS:
DNA replication-
Segregation-
Cytokinesis-

16. Binary Fission Who does this?? Bacteria – Similar to mitosis
Except DNA not in chromosomes in a big circle.
Eukaryotic single cell organisms like amoeba and paramecium
Identical to mitosis

18. Type: Budding

19. Budding
Organism grows an exact copy of its self off an area of its body
When the clone is large enough it falls off and can live independently
New organism will grow to be an identical copy of parent organism

20. Budding
Who does it?
Yeast
Hydra

21. What’s a Hydra
Freshwater animal. They are usually a few millimeters long and are best studied with a microscope.

22. What if Humans could reproduce by budding??
Creepy!

23. Type: Sporulation

24. Sporulation Spores released into air Once land, reproduce by mitosis
New organism is identical to parent

25. Sporulation
Who does it?
Fungus
Ex. mold

26. What if we did this??
As we shed skin cells we’d leave a trail of babies??

27. Type: Vegetative Propagation

28. Vegetative propagation
When a part of a broken plant is broken off
Buried and grows
Matures into an adult plant through mitosis
New plant is Identical to Parent

29. Vegetative propagation
Many plants can develop from parts that are broken off intentionally by humans or separated naturally by parent plant

30. Vegetative Propagation
Who does it?
strawberry plant runners
gardener puts piece of geranium leaf or potato in water to root

31. Type: Regeneration

32. Regeneration
a lost or damaged part if the part regrows so that the original function is restored
Some can regenerate more than others (differs from organisms to organism)

33. Regeneration
Organism missing body part will grow a new body part but… DUN DUN DUN
The body part will grow a new body!

34. Regeneration
Who does it?
Daddy Long Leggars
Starfish
Lizards
Worms

35. Plants? Do plants reproduce sexually, asexually or both?
Sexual or Asexual?
Seeds
Fruit
Self Pollination
Cross Pollination
Vegetative Propagation
HOW CAN YOU TELL??
USE THE COMPUTER TO RESEARCH EACH OF THESE TYPES OF REPRODUCTION USED BY PLANTS (take notes)

36. Step 2: Research this type of reproduction (notes, internet)
Project Guidelines:
Step 1: Looking at the below list, determine which type of asexual reproduction you will be depicting (Check with other groups because each type may only be used once; in the case of duplicates each group will receive a ZERO)
Step 2: Research this type of reproduction (notes, internet)
Step 3: Brainstorm how to creatively depict this type of Reproduction
Step 4: Create a poster, comic book, short story, flip book, etc that depicts the type of reproduction
Step 5: On the back of your work include the following
Title: Type of Reproduction
Description of the process of this type of reproduction
Description of the offspring produced during this type of reproduction (genetics)
Binary Fission
Budding
Sporulation
Vegetative Propagation
Regeneration
Mitosis
Meiosis
