Describe reproduction in living organisms.

Explanation

In multicellular organisms reproduction refers to the production of progeny possessing features more or less similar to those of parents
Fungi multiply and spread easily due to the millions of asexual spores produce by them.
Budding is observed in lower organisms like yeast and hydra.
 In Planaria (flat worms) regeneration is seen is a fragmented organism regenerates the lost part of its body and becomes a new organism.
Fragmentation is seen in fungi, filamentous algae and the protonema of mosses.
Unicellular organisms like bacteria, unicellular algae or Amoeba, reproduction is synonymous with growth means increase in number of cells.
Growth can be define as equivalent to increase in cell number or mass.
Hence, in single-celled organisms it is not very clear about the usage of these two terms - growth and reproduction.
There are many organisms which do not reproduce like as Mules, sterile worker bees, infertile human couples etc.
Hence, reproduction cannot be considered as defining characteristic of living organisms.
No non-living object is capable of reproducing of replicating by itself.
