The process of reegeneration is the natural ability of living organisms to replace worn out parts,repair or renew damaged or lost parts of the body,or to reconstitute the whole body from a small fragment.Thus it is also a developmental process that involves growth,morphogenesis and differentiation.
Planarian is an non-parasitic flatworms that exhibit extraordinary ability to regenerate the lost body patrs.However it also undergo the process of reproduction.There are sexual as well asexual planaria.Sexual planaria are hermaphrodites,having both testicles and ovaries.One of their gametes will combine with the gamete of another planarian.Each planarian transports its excretion to the other planarian,giving and receiving sperm.Eggs develop inside the body and are shed in capsules which later hatch and grow into adults.In asexual reproduction the planarian detaches its tail end and each half regrows the lost parts by regeneration to divide and differentiate thus resulting in two worms.Some species of planaria are exclusively asexual whereas some can reproduce both sexually and asexually.
