(text pages 29-35)

2. Asexual Reproduction
The formation of a new individual that has identical genetic information to its parent.

3. Reproduction
Asexual
Sexual
Binary Fission
Budding
Spore Formation
Fragmentation
Vegetative
Conjugation
Separate Sexes
Hermaphroditic

4. Bacteria (see p. 29-30 in text)
Have no nuclear membrane (prokaryotic)
Have only one chromosome
Reproduction asexually by the process of binary fission.

5. Binary Fission Steps (see p. 30) cell wall ruptures
single chromosome gets copied
cell grows longer and a chromosome moves to each end.
cell membrane pinches off.
cell wall grows to surround both cells.

7. Protists Examples include paramecium, amoeba, euglena, vorticella
Protists
Examples include paramecium, amoeba, euglena, vorticella
unicellular organisms with a true nucleus (eukaryotic).
mitosis takes place creating two identical cells.

8. Fungi Examples include moulds, yeast, and mushrooms.
Examples include moulds, yeast, and mushrooms.
Filaments called hyphae grow over the surface of food.

9. Fungi have 3 methods of asexual reproduction 1) Fragmentation
Athletes Foot Fungi
– a small piece of hyphae breaks away and grows into a new individual. It is identical to its parent. (fungi – p 32)

10. 2) Budding a copy of the nucleus is made.
2) Budding
a copy of the nucleus is made.
- The nuclei press against the cell membrane, forming a bud which grows and breaks off. (hydra & yeast)

11. 3) Spores
– special cells called spores are stored in a case called a sporangium. The spores are released when ready and go through mitotic cell division if they land in suitable conditions. (bread mold – p 33)

12. Animals Invertebrates (without backbone) make up 97% of animal species
Example, Planaria (Flatworms) – divide in two and replace the parts that are missing.
Example, Sponges and hydras – reproduce by budding. see pg 35.
