WHOA! New Organism Discovered! Plants too are ?Budding?!
Budding is one of the kind of asexual reproduction in which a new organism is developed from an outgrowth or bud of the cell due to cell division that happens at one particular site.
Budding is one of the kind of asexual reproduction in which a new organism is developed from an outgrowth or bud of the cell due to cell division that happens at one particular site. The new organism continues to be attached to its parent organism as it slowly grows and only detaches or separates from the parent when it becomes mature, leaving behind a scar tissue.
This type of reproduction is asexual; hence the newly created organism is genetically similar to the parent organism and is a clone of the parent. Endopolygeny is the process of division of several organisms at once through internal budding.
BUDDING IN YEAST
Yeast is a eukaryotic, unicellular organism which is a non-green fungus and is reproduced through the method of budding. The size of the yeast can vary with the type of species it belongs to.
Steps of budding in yeast-
?A small bud appears as an outgrowth or bud from the parent body.
? The nucleus of the parent yeast starts to get separated into two parts.
?One of the nucleus shifts towards the bud until it reaches inside the bud.
? The newly created bud starts dividing and grows into a new cell.
Note: even though there is equal division of the genetic material of the parent cell, there is however unequal division of the cytoplasm during the replication. The daughter yeast produced is generally smaller in size than the mother yeast.
The process of budding is extremely fast in the yeast. It is because the first bud starts forming the new buds even before it has detached from the parent yeast cell. Development of a small chain of buds takes place in this way which finally leads to the breakdown of all the buds into new yeast cells.
ADVANTAGES OF BUDDING IN YEAST
? Since budding of yeast is an example of asexual reproduction, the yeast does not require a mate to replicate. Hence, it saves the time and energy that is used for searching a mate.
? There is production of large number of offspring in a very less time.
DISADVANTAGES OF BUDDING IN YEAST
?There is hardly any genetic variation in the given population.
?If there is any kind of change or mutation in the parent yeast, then the harmful effects would be caused on the survival ability of the offspring yeast.
