Regeneration & Fragmentation Regeneration-Regrowth of body parts. Regeneration is not reproduction. Fragmentation- an organism breaks into two or more pieces (fragments) and each piece regenerates. Fragmentation is a form of reproduction.

Prefix “Bi” means TWO… Bacteria reproduces by splitting into 2! Binary Fission is… When bacteria (and some protists) divides into two bacteria. Similar to mitosis… but since bacteria do not have a nucleus, they don’t need to go through the same phases (prophase, metaphase, and anaphase) Prefix “Bi” means TWO… Bacteria reproduces by splitting into 2!

Binary Fission

Sexual Reproduction Types include: Fertilization Pollination

Fertilization Combination of sperm and egg Results in increased genetic diversity (combined traits)

Sexual- Meiosis Asexual-Mitosis Advantages Can adapt to environmental change- Some of the population may survive even after a change in environmental conditions Only one parent needed- reproduction can happen at any time. Quick- can produce a large population in a short time Offspring are genetic mix of both parents- genetic diversity/ variation in traits Does not need much energy- few resources required

Sexual- Meiosis Asexual-Mitosis Disadvantages Slow – can only produce a small population in a short time Limited ability to adapt – whole population could die off if their environment changes Lots of energy needed – must find mate before reproducing Offspring genetically identical to parents – no genetic diversity/ no variation of traits 2 parents needed - Reproduction requires both parents to be together, mature and fertile
