DEFINITION: Fragmentation or Clonal Fragmentation is a form of asexual reproduction or cloning where an organism divides into fragments. Each of these fragments develops fast and good that are a clone of the original organism.

Fragmentation is seen in many organisms such as molds, some annelid worms, and sea stars.The division of two elements of single-celled organisms such bacteria, protozoa and algae is a type of fragmentation.

Molds, yeast, and mushrooms, all of which are part of the Fungi kingdom, produce tiny filaments called hyphae. These hyphae obtain food and nutrients from the body of other organisms to grow and fertilize. Then a piece of hyphae breaks off and grows into a new individual and the cycle continues. Fragmentation is observed in nonvascular plants like, liverworts and mosses.

REFLECTIONS: If asexual reproduction (clonning) is natural, why is it negative in humans? Because the life cicle would be altered and we would never die, also we would have overpopulation because we clone many people and we would have resource shortages of food, and money.

What could happen if humans clone? We will lose the sexual reproduction, and we couldn`t see diversity of type of people, black people, yellow, etc...
