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.

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 Only one parent neededreproduction can happen at change- Some of the population may survive even any time. after a change in Quick- can produce a large environmental conditions population in a short time Offspring are genetic mix of both parentsgenetic diversity/ variation in traits Does not need much energyfew 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 2 parents needed Reproduction requires both parents to be together, mature and fertile Offspring genetically identical to parents – no genetic diversity/ no variation of traits
