Asexual Reproduction

Chlorophytum comosum, also known as the spider plant is a green plant that reproduces asexually. This plant uses the budding process. The process takes places as the stems extend from the buds of the plant and eventually form into tiny plants identical to its parent.

Asexual Reproduction

Asexually produced offspring look very different from Sexually produced offspring. First of all, asexually produced offspring are identical to its parent and have 100% of their phenotype. An example are the spider plants, that all look exact. Also twins are the product of asexual reproduction originating from sexual reproduction. Twins look close to identical. Sexually produced offspring get 50% of one parent and 50% of another one's phenotype. It has a higher chance of looking totally different from its parents and since it all connects, it has a chance of looking like its ancestors. Some sexually producing organisms are bees, lizards and humans.

The naval orange tree reproduces asexually as well. The process they use is propogation. An example of propagation is when human takes the cutting of a tree and plants it or sows the seeds. Due to its seedless feature, propogation is the only way this tree will reproduce.

To the right is The hydra( genus) is a translucent tubular organism. It also asexually produces by using the form of budding, in which it grows buds on the body. Then the new copies mature and break away to form into new hydras.

Benefits and Drawbacks

Benefits:- no energy needed in finding and competing for a mate- quick reproduction when neededex: when not many other plants with pollen are available, asexual reproduction is very useful and needed. Disadvantages: - one small, bad mutation can result in generations of vulnerable organisms- one disease can destroy entire colonies - when reproduction gets out of hand or too fast, can result in high competitionEx: bananas are naturally susceptible to panama disease and since they dont sexually reproduce their generations have the same percent of suscpetibilty for this disease

Shown above is the byrophyllum( kalanchoe) which is native to South Africa and Asia. This succulent asexually reproduces in the form of vegetative cloning which includes budding and cutting. At the edges of the plant the new plantlets grow and soon detach into a new copy of a byrophyllum.
