Example: Spirogyra. 1. Planaria is a genus of planarians in the family Planariidae.It is currently represented by a single species, Planaria torva, which is found in Europe. Each fragment results in the growth of a separate, individual and independent organism, which are clones of the parent organism. Spirogyra sp. (a) Fragmentation is defined as the process of breaking up of body on maturation into two or more smaller pieces. 1 answer. Fragmentation in operating system: In this tutorial, we are going to learn what is fragmentation, cause of fragmentation, types of fragmentation, etc. Fragmentation enables you to define groups of rows or index keys within a table according to some algorithm or scheme.You can store each group or fragment (also referred to as a partition) in a separate dbspace associated with a specific physical disk. Illustrate the following with the help of a suitable diagrams: (i) Regeneration in Planaria (ii) Budding in Hydra (AI 2008) Answer: (i) Regeneration in Planaria Planaria: If it is divided into 3 parts a, b and c, each part grows as a new individual. 35.4.2 Planaria. The organism may develop specific organs or zones to shed or be easily broken off. Fragmentation. Structure of a Flower or Pollination in Flowers: Here you have to depict the structure of flowers with proper labelling. Planaria are hermaphroditic, meaning they have both male and female sex organs. Common forms of asexual reproduction include: budding, gemmules, fragmentation, regeneration, binary fission, and parthenogenesis. Draw a labelled diagram to illustrate budding in Hydra. With neat diagrams explain the process of regeneration in Planaria. With neat diagrams explain the process of regeneration in Planaria. (a) Fragmentation is a mode of asexual reproduction. Regeneration is the process in which an organism is cut into several parts and develop into new individuals from each piece. This is a type of _____ reproduction. Intestinal regeneration in planaria is neoblast dependent [125].Investigators have shown that the intestine originates from mesenchymal cells associated with the enteric muscle. The process of getting back a full organism from its body parts is called regeneration. ← Prev Question Next Question → +1 vote . An organism is split into fragments and each fragment grows into complete individual organism. small pieces of their bodies can give rise to new individuals.This process is called as fragmentation. [NCERT Exemplar] Answer: They are considered as asexual types of reproduction as all of them involve a single parent and no fusion of gametes take place in them. (a) Fragmentation: Multicellular organisms with simple body organisation such as filamentous algae-Spirogyra breaks up into two or more small pieces or fragments upon maturation. There are several other known mechanisms of natural fragmentation in plants. Fragmentation is a very common type of vegetative reproduction in plants. The name planarian is used to designate any member of the family Planariidae and related families. The network layer divides the datagram received from transport layer into fragments so that data flow is not disrupted. ; Regeneration takes place through a specialized cell that helps in the proliferation or growth of a large number of new cells. Answer: Budding, fragmentation and regeneration are considered as asexual types of reproduction because gamete formation does not happen during these modes of reproduction and a single parent carries out the process of reproduction. 951 views. Question 2. Planarian, any of a group of widely distributed, mostly free-living flatworms of the class Turbellaria (phylum Platyhelminthes). Regeneration in Planaria : If the individual body of the planaria are cut or broken up into many pieces, many of these pieces grow into separate individuals. Name any other organism in which a similar process can be observed. regeneration is when a planaria loses a piece of it's body, it can re-grow that mission piece...fragmentation is a form of reproduction, in which planaria divides and creates another planaria, i think, i am not too sure, this is what i remember from bio class, sorry, have a good day The simple animals like hydra and planaria show regeneration. 2)In budding, the new organism is from the old organism, its kind of sprouting out.
