REPRODUCTION Part 1
... When an organism passes all of its DNA onto its offspring and the offspring are identical to the parent, it is called asexual reproduction. One-celled organisms usually reproduce asexually. Their cells divide to form two identical cells. Protists, fungi, and some plants and animals can reprodu ...

Dictyostelium discoideum
Dictyostelium discoideum is a species of soil-living amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa. Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime. Its unique asexual lifecycle consists of four stages: vegetative, aggregation, migration, and culmination. The lifecycle of D. discoideum is relatively short, which allows for timely viewing of all stages. The cells involved in the lifecycle undergo movement, chemical signaling, and development, which are applicable to human cancer research. The simplicity of its lifecycle makes D. discoideum a valuable model organism to study genetic, cellular, and biochemical processes in other organisms.
