Asexual reproduction, Antonia Cabal, Nicolás Pérez, Jacobo José Morales -…
Asexual reproduction
Gemmules (Internal Buds)
An internal bud is a form of asexual reproduction in which
the host unleashes a unique cell cluster that is capable to develop into an offspring.
Example:Sponges
In sponges budding works by them creating a mass of cells that are able to form into a new organism.
In one the offspring grows on the body of the parent, whole in the other it grows inside the body of the parent
Fragmentation
The body of the parent breaks into distinct pieces, each of which can produce an offspring. The detachment of the parts is intentional, and if thy are large enough, the detached parts will develop into new individuals.
Example: Planarians
They split into fragments, which develop into adult planaria
-
Regeneration
This typically happens when a part, like an arm, becomes detached from the parent's body. The separated piece can grow and develop into a completely new individual. Regeneration can be thought of as a modified form of fragmentation.
Example: Star fish
When the arm of a star fish is separate from the parent body
it generates the arm and the arm that was broken get clone
-
Diferences
In regeneration, the part that was broken regenerates no matter the size
Budding
An offspring grows out of the body of the parent, then breaks off into a new individual. Usually budding is restricted to certain specialized areas, and the offspring typically remain attached to the parent until it is mature.
Example: Hydras
They produce buds in the body wall, which grow to be miniature adults and break away when they are mature.

Binary Fission :
Example: Paramecia
During binary fission Paramecia duplicates its organelles and grows in size to then divide into two identical daughter cells.
Binary fission is the process in which a parent cell replicates it's "Organelles" and grows it's size by a procedure called mitosis, after that the cell splits in two duplicates called daughter cells.
Parthenogenesis
Example: Water fleas, most wasps, bees, and ants; some reptiles and fish
Involves the development of an egg that has not been fertilized into an individual. Most organisms that reproduce through this method can also reproduce sexually.
All of them
Disadvantages
-
-
-
-
-
Extreme growth may lead to rapid depletion of resources and an exponential death rate in the population
Advantages
A constant similarity that is noticed, is that asexual reproduction
will include some sort of cell splitting or division that will grow a new organism
