The ability of a fully differentiated organism to give rise to new individuals from their body parts is known as:
Fragmentation
fission
budding
regeneration
regeneration
Regeneration is the ability of a fully differentiated organism to give rise to new individuals from their body parts. When an organism is cut or broken into pieces, many of these pieces grow into separate individuals.

Similar to how a lizard can regrow its lost tail, organisms like Planaria and Hydra can regrow their entire bodies from small severed fragments due to the presence of highly active specialized cells.
REGENERATE = Re-Grow Every Given Part As New Entire Tissue
Regeneration is carried out by specialized cells known as stem cells or undifferentiated cells. These cells proliferate and undergo rapid mitotic division, followed by morphallaxis or epimorphosis to differentiate into various tissues and organs, thereby rebuilding the entire organism from a small body part.
Regeneration is exhibited by organisms like Planaria (flatworms) and Hydra.
It involves specialized cells that proliferate to form a mass of cells, which then differentiate into various cell types and tissues.
Fully differentiated organisms can regenerate lost body parts or give rise to new individuals.
Not all organisms possess high regenerative capacity; complex animals have limited tissue repair (e.g., wound healing).
Allows recovery and survival after severe physical injury or predation.
Can result in asexual reproduction in lower invertebrates.
Energy-intensive process requiring active cell division and differentiation.
Absent or severely limited in complex multicellular vertebrates.
Wound healing and tissue repair in various animals.
Asexual reproduction in Planaria, Hydra, and starfish.
Fragmentation involves breaking into parts where each part develops into an organism, but regeneration specifically emphasizes the ability of fully differentiated body parts using specialized cells.
Option A (Fragmentation) is a simpler form of splitting found in Spirogyra, whereas Planaria specifically undergoes regeneration via specialized stem cells.
D is correct тАФ The ability of a fully differentiated organism to give rise to new individuals from their body parts is known as regeneration.
Remember that while fragmentation (like in Spirogyra) happens due to accidental breaking of filaments, regeneration (like in Planaria) involves specialized cells
