1. 1/9/14 Pick a partner or work by yourself
Grab a chart and one set of organisms. from the front table. ONE PER GROUP
Begin reading about your organisms and fill in you chart.
You will have until 10 mins after the bell rings to complete this task.

2. Reproduction
Asexual and Sexual

3. All Living Things…… Are made of cells, Require energy,
Grow and develop,
Respond to their surroundings (stimulus/response)
Display organization
Maintain homeostasis
Adapt and evolve over time
REPRODUCE

4. Thinking Points What is the result of reproduction?
Why do organisms bother to reproduce? Why don't they just live forever?
What would eventually happen to a species if every member suddenly lost its ability to reproduce?

5. Reproduction=making babies!

6. Two Types of Reproduction
Asexual reproduction - production of genetically identical offspring from a single parent.
Sexual reproduction - production of genetically different offspring from two parents.

7. DNA is an instruction manual for an organism
Review:
What does this word “genetic” mean anyway?
DNA
DNA is an instruction manual for an organism

8. Asexual Reproduction 5 Types You Need to Know
Binary Fission
Vegetative reproduction
Budding
Spore formation
Regeneration
BRAIN POP!

9. Binary Fission
Prokaryotic cells divide into 2 genetically identical cells

10. Vegetative Reproduction
Production of a new plant from a portion of another plant, such as a stem or branch. Also called vegetative propagation.

11. Budding
Budding is the process of a parent organism pinching off to form a new organism genetically identical to the parent.

12. Spore Formation
Spores are released from parent to produce genetically identical offspring. (Bacteria, plants, algae, and fungi.)

13. The ability to replace or regrow missing body parts
Regeneration
The ability to replace or regrow missing body parts

14. Is a form of Sexual Reproduction

15. Cojugation

16. Disadvantages
Asexual – no genetic variation (less genetic diversity among the species) so less chance for survival if environment should change
Sexual –
takes longer to make offspring,
requires two parents,
can’t reproduce as often in a single lifetime

17. Advantages Asexual Requires only one parent
Organisms can reproduce rapidly
Requires less metabolic energy
No special sex organs necessary
Low genetic variability allows a higher success rate AS LONG AS THE ENVIRONMENT DOESN’T CHANGE.

18. Advantages
Sexual –
Because DNA from two parents is combined, lots of genetic diversity
Organisms reproduce less frequently
Genetic variation allows better chance for survival if environmental conditions should change
Genetic variation can lead to resistance to certain types of disease
Genetic variation enables evolution within a population

19. Who does it?
Asexual – organisms from the archaebacteria, eubacteria, and Protista kingdoms, some fungi, some plants, and some simple animals
Sexual – most animals and plants, some protists, some fungi, humans, some prokaryotes (conjugation).
