Fragmentation (biology definition): (1) a form of asexual reproduction wherein a parent organism breaks into fragments, each capable of growing independently into a new organism, (2) breaking into smaller parts or fragments. Synonyms: spallation.

What is the process of fragmentation?
During the process of fragmentation, a fragment of the parent forms a new being. It occurs when a shoot that is rooted becomes detached from the main group. Multicellular organisms with simple body organization can divide or reproduce by fragmentation.
What happens during fragmentation?
Fragmentation is a form of asexual reproduction where a fragment of the parent breaks off and develops into an entirely new but genetically identical individual. The parent will then regenerate, or regrow, the piece that broke off, so in the end there are two new individuals from one.
How does plant fragmentation occur?
Among plants, fragmentation is the regularly found type of asexual reproduction. Fragmentation is a very common type of vegetative reproduction in plants. Fragmentation occurs when a shoot that is rooted becomes detached from the main group.
What is an example of fragmentation?
The definition of fragmentation is being broken down into sections. An example of fragmentation is cutting a worm into pieces.
What is fragmentation in class 10?
(a) Fragmentation is a mode of asexual reproduction. Fragmentation is the process in certain multi-cellular organisms with relatively simple body organisation, the body of the organism simply breaks up into smaller pieces upon maturation and these pieces or fragments grow into new individuals. Example: Spirogyra.
What is fragmentation short answer?
Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. The fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms.
Can a starfish reproduce?
Reproduction: Sea stars are broadcast spawners. Males release sperm into the water and females release eggs. The fertilized eggs hatch into a larval form that lives as plankton, sometimes for months, before settling on the sea floor in its adult form.
Where does fragmentation occur?
Fragmentation is done by the network layer when the maximum size of datagram is greater than maximum size of data that can be held in a frame i.e., its Maximum Transmission Unit (MTU).
What is fragmentation in a file system?
File fragmentation is a term that describes a group of files that are scattered throughout a hard drive platter instead of one continuous location. Fragmentation is caused when information is deleted from a hard drive and small gaps are left behind to be filled by new data.
Is fragmentation occur in earthworm?
Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism is split into fragments.Fragmentation as a method of reproduction is seen in organisms such as filamentous cyanobacteria, molds, lichens, sponges, acoel flatworms, some annelid worms and sea stars.
Does yeast reproduce by fragmentation?
As the bud formation does not take place in all the above options other than the budding process. Therefore, Yeasts cannot be reproduced by pollination and fragmentation.
Do bacteria do fragmentation?
In more complex organisms, such as colonial bacteria, reproduction involves fragmentation of a group of cells into smaller groups. Bacterial species demonstrate a wide range of fragmentation modes, differing both in the size at which the parental group fragments and the number and sizes of offspring groups [5].
How does fragmentation take place in spirogyra?
-Fragmentation is the process of vegetative reproduction in spirogyra. –The filament of spirogyra breaks into different fragments due to the presence of mechanical injuries. -Each of the fragments of the filament will grow into a full-grown new individual which is similar to their parents.
What animal uses parthenogenesis?
Most animals that procreate through parthenogenesis are small invertebrates such as bees, wasps, ants, and aphids, which can alternate between sexual and asexual reproduction. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish or lizards.
Is Hydra do fragmentation?
B) Budding. C) Fragmentation.Complete answer: Asexual reproduction in Hydra takes place by budding. Budding is the reproduction technique which produces new young hydra from the small part of the parent body.
What is fragmentation in biology class 12?
Fragmentation: Fragment means, breaking into parts. So, in the fragmentation process, the body is broken into parts. Then each part of the organism will be developed as individual parts of the body. This is a type of reproduction that happens in lower organisms.
What are fragments in Android?
According to the Android documentation, a fragment is a part of applications user interface that is bound to an activity. Fragments have their lifecycle and layouts or UI components. Fragments help enrich your UI design, pass data between different screens, and adapt to different device configurations.
What is meant by fragmentation Class 7?
The breaking up of the body of the parent plant in two or more pieces on maturing , each of which subsequently grows to form a new plant, is called fragmentation.
What is fragmentation give the types of fragmentation explain?
Fragmentation is an unwanted problem where the memory blocks cannot be allocated to the processes due to their small size and the blocks remain unused.Basically, there are two types of fragmentation: Internal Fragmentation. External Fragmentation.
What is fragmentation regeneration?
Fragmentation is a method of asexual reproduction where an organism reproduces by the process of splitting into fragments and each fragment grows into an individual organism. Regeneration, on the other hand, happens when an organism regrows certain parts or limbs which is lost due to predation.
