Title: Cell Growth


1
Cell Growth Division
  • Asexual Reproduction

Sexual vs. Asexual Reproduction
Sexual Asexual
Parents 2 Parents Required to produce 1 Offspring 1 Parent required to produce 2 Offspring
GeneticDiversity Each Offspring Genetically Unique Each Offspring Genetically Identical To Parent
Advantages Genetically Unique Offspring. Genetic diversity, may allow offspring to adapt to unfavorable conditions More Efficient Under Favorable Conditions , Shorter Reproductive Cycles
Disadvantages Longer Reproductive Cycles Genetically Identical Offspring, may not be able to adapt to unfavorable conditions

Asexual Reproduction In Eukaryotes
  • Common In Simpler Plants Animals
  • Organism Can Choose Between Sexual or Asexual
    Reproduction, Based On Conditions
