  ASEXUAL REPRODUCTION PART 2 Fragmentation:- Some organisms have simple body organization like Spirogyra , they break down into smaller pieces each piece forms new identical individual, this mode of reproduction is known as Fragmentation. Fragmentation in Spirogyra Regeneration:-  Many fully differentiated organisms have the ability to give to an individual organisms from their body parts. That is, if the individual somehow cut or broken up into many pieces, many of these pieces grow into separate individuals. For example, simple animals like Hydra and Planaria can be cut into any number of pieces and each piece grows into a complete organism. This is known as regeneration. Budding:-  Organisms such as Hydra use regenerative cells for reproduction in the process of budding. In Hydra, a bud develops as an outgrowth due to repeated cell division at one specific site,  These buds develop into tiny individuals and when fully mature, detach from the parent b...
  MODES OF REPRODUCTION USED BY SINGLE ORGANISMS                                                            Part 1 The modes by which various organisms reproduce depend on the body design of the organisms. Unicellular organisms reproduce by means of following processes:- Fission:-   Fission is the process of spliting of unicelluar organisms or single celled organisms into the two are more than two cells, each cell forms the new individual. The new individual formed is exact copy of parent cell. Fission is of two types:-            A) Binary Fission:-  when the single parent cell divides into two new daughter cells, each new                                                ...
