3. Sexual and Asexual Reproduction.

4. Living Things Reproduce
2 Types of Reproduction:
Asexual
Sexual

5. Asexual Reproduction:
One parent producing an offspring genetically identical to itself (parent)
Offspring can live independently

6. Types of Asexual Reproduction In Animals
Budding: happens when a part of the parent organism pinches off and forms a new organism.
The new organism separates from the parent and lives independently.
Jellyfish & hydra

7. Budding Organism develops tiny buds on its body Asexual reproduction
Buds form from the parent cell so the bud is identical to the parent.
Both unicellular and multicellular
Examples: hydra, plants, some yeast

8. VIDEO
SpongeBob

9. Types of Asexual Reproduction In Animals
Fragmentation: parts of the organism break off and a new organism grows identical to the parent.
Worms & starfish

11. Types of Asexual Reproduction In Animals
Regeneration: organism loses a body part and that part may develop into a new organism or simply reform.
Sea star

12. Regeneration:
Specialized cells grow new tissue when a wound or lost limb occurs
Examples: Starfish, lizard tails, planarian, cuttings from plants….

13. Cell Division in Unicellular Organisms
Binary Fission:
form of asexual reproduction in prokaryotic (lacks nucleus) organisms
Parent organism splits in half
(Eukaryotic – reproduce by mitosis ex: algae, some yeast, protozoans like paramecium)

15. Spores:
Single-celled asexual reproductive unit of non-flowering plants, bacteria, fungi, and algae
Identical to parent
Released by parent organism
Think of them like seeds; they are made to grow a new plant and all they need is the proper environment to thrive.

16. Spores
Spore Formation – spores = small specialized cells that contain a nucleus and cytoplasm surrounded by a thick outside wall which protects the spore. Under the right conditions the spore can rise to a new organism. Found in bacteria, molds, yeast, mushrooms, mosses, ferns and some protozoans.

19. Sexual Reproduction
Produces offspring that have a combination of genes inherited from two parents sex cells or gametes.
Sperm
Eggs

20. Sexual Reproduction Fusion of two gametes to produce a single zygote.
This fusion is called fertilization.
Sperm
Eggs

21. Sexual Reproduction Two parents egg (female) and sperm (male)
Fertilization – when egg and sperm unite
Plants growing from seeds and animals growing from eggs
Creates the diversity of life on earth
Offspring is unique

23. Advantages and Disadvantages of Sexual and Asexual Reproduction:
Body cells have extremely fast reproduction
All identical
All are different (strong traits survive)
Slow/small reproduction
Disadvantages
Rapid growth can kill off some organisms – they will compete to survive
If one gets damaged, offspring are damaged
1. Damaged offspring – traits can kill organism or carry on damaged genes

24. Asexual Reproduction One parent Identical to parent
More likely to get disease
budding, fragmentation, regeneration, binary fission, spore formation

25. Sexual Reproduction Two parents – male and female
Unique offspring ( not identical to parents)
Egg, sperm
Fertilization ( egg and sperm unite)
More resistant to disease

26. Asexual or Sexual
Reproduction

27. #1 Offspring forms by pinching off the original parent
Sexual reproduction
Budding
Regeneration
Spore formation

28. #2 Reproduction involving male (sperm) and female (egg) Fission
Asexual reproduction
Sexual reproduction
budding

29. #3
Form of reproduction resulting from a prokaryotic cell splitting in two
Spore formation
Binary fission
Regeneration
budding

30. #4 Results in an offspring being created Fission Budding Reproduction
regeneration

31. #5 New tissue or limb reforms by reproducing asexually Budding
Regeneration
Binary fission
Sexual reproduction

32. #6
When under the right circumstances, like warmth and wetness, can create a new organism
Budding
Binary fission
Spore formation
regeneration

33. #7
Which of the following does NOT result in an offspring identical to the parent?
Budding
Asexual reproduction
Sexual reproduction
fission

34. #8
Asexual reproduction results in new bacteria whose genetic material is
Identical to that of the parent
Not identical to that of the parent
Half identical to both parents
Identical to that of another parent

35. #9
In sexual reproduction, the offspring receives its genetic makeup as
All from the mother
All from the father
Half from the mother
Half from the mother and half from the father

36. #10 All of the following are types of asexual reproduction EXCEPT
Budding
Fertilization
Regeneration
fission

37. #11
Which example could only be classified as an outcome of sexual reproduction?
when one parent combines its genetic information with another parent to produce offspring Fertilization.
when two of the offspring are produced from one parent.
when all of the offspring are genetically identical.
when the cells in the offspring have the same number of chromosomes as cells in the parent.
