FRAGMENTATION

ASEXUAL REPRODUCTION:
Asexual reproduction is a mode of reproduction in which some living beings give just one cell from their own body, is the formation of an individual from one cell of a single parent.


DIFFERENT MODES OF ASEXUAL REPRODUCTION:

  • Budding
  • Fragmentation
  • Regeneration
  • Fission
  • Spore
  • Polyembroyny
  • Parthenogenesis
FRAGMENTATION:
Is when a living being splits in a fragment or more fragments, is like if they were cloning exactly how they are in a natural way, their own body is the one who divides in parts like corals, worms and starfish:

REFLECTIONS:
- As we had seen, to clone is a natural process of reproducing, but the science is not better than nature, because the nature makes that some animals can clone their own bodies with out chemical substances. Humans think they can surpass the limits of nature, and they are better than nature.


- Nature decided what is the mode of reproduce of each specie and nature decides that humans have to reproduce by sexual relations, is no normal that humans prefer to clone their bodies than to have sexual relations to make new life, if people clone their bodies we couldn't 
name our descendants as daughter, son , goddaughter , etc.
