The advantages and disadvantages of asexual reproduction in plants
Asexual reproduction in the plants
The asexual reproduction is the production of new plants without using of seeds , it can incorporate new characteristics into the plants , it is easier and cheaper , it can produce uniform plants , and some plants do not produce the seeds .
Some plants have developed special type of asexual reproduction called the vegetative reproduction which takes place via the parts of the root , the stem , the leaves or the buds , there are two kinds of vegetative reproduction which are the natural vegetative reproduction and the artificial vegetative reproduction .
The natural vegetative reproduction takes place by many ways such as reproduction by the rhizomes , the corms , the tubers , the bulbs , and the offshoots , And the artificial vegetative reproduction takes place by three ways which are cutting , grafting and the tissue culture .
The asexual reproduction produces new individuals without the fusion of gametes , They are genetically identical to the parent plants and each other , except when the mutations occur .
Advantages Of the asexual reproduction
The organism that reproduces asexually has the ability to take many different extensive forms which allow asexual reproduction to succeed in various environments ?
The asexual reproduction is only performed in the organisms that often stay in one place , It does not need mobility , So , most plants have a great ability to create their offspring as this process doesn’t need to move to another place .
The asexual reproduction has rapid increase of offspring which is very helpful in producing lots of offspring ? It lets the plants make lots of offspring effectively which will help them in increasing their genes .
The asexual reproduction is not complex , It requires less energy compared to the sexual reproduction , and There is no need for much time or energy to produce the offspring , so , the plants can produce many offspring without considering the amount of time or energy to consume .
The asexual reproduction does not need to look for a mate as looking for a mate is difficult or impossible with the sexual reproduction especially when colonizing new areas and it needs only one parent which is ready to reproduce .
When the organism is established in a suitable habitat , it can reproduce rapidly to produce many new individuals , and the stable environments with very little change are favourable for the organisms to reproduce asexually .
Disadvantages Of Asexual Reproduction
Most organisms which only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments .
Only one parent plant is required for the asexual reproduction , the new plants are identical to the parent so that good features will always be passed on , the chromosomes and genes of the parent will be copied , So , there will be genetic defects or the mutation in the offspring with no exception .
The asexual reproduction does not have the genetic diversity , There is less variation produced with the offspring , and the organism becomes less adapted to certain environmental changes , the entire communities will not adapted to the harsh environment .
The asexual reproduction usually leads to struggle for the existence as well as the overcrowding , and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce .
